Multi-Species Bravo!

Bravo_1_XC
The Pro Finish Bravo I LT propeller is designed specifically for higher horsepower, single engine outboard powered bay boats and multi-species hulls under heavy loads.

A number of boat manufacturers have responded to angler requests for larger and more stable hulls. The changes have resulted with the consoles moving forward, changing the center of gravity and weight distribution. The mounting of trolling motor batteries in the front of the boat affects planing performance and bow lift as well. The new hull designs, while user friendly in terms of fish ability come with a price in terms of overall engine performance.

It didn’t take long before I started getting calls  from customers asking for help in enhancing the performance of their single engine outboard powered bay boats and multi-species hulls under heavy loads. Our trusty Bravo I FS was no longer the viable option for these applications.

Our solution? The all new Pro Finish Bravo I LT (Long Tube). This hand-crafted, stainless steel prop is designed to improve planing and trim response throughout the engine operating rpm range. The result? An increase in top-end speed by 1 to 1.5 mph!

Cavitation plates were set level throughout the test.

I worked with our Product Integration Manager Mike Griffiths to test the Bravo I LT. Mike secured a representative test hull locally from a friend. The subject boat was a multi-species Nitro 21 ZV with a 300 Pro Verado.  Mike tested a 22″ pitch Bravo I LT against a 22″ pitch Bravo I FS and a 21″ pitch stainless steel 3-blade prop.

It  was obvious the 3-blade doesn’t compare to the 4-blades when running in rough water.  The 3-blade fails to hold the bow up, resulting in a rough, unsettled ride. Performance of the Bravo I FS and LT was close – but the overall top speed winner was the LT.  Where the LT really shined was acceleration. The LT also maintains engine rpm better through the turns when compared to the FS.

Chase’s tournament ride: A 21-foot Nitro ZV with a 350 Verado.

Many times I’ll work with people in the field to get real-world application testing of prototype props to ensure we are addressing all of the issues we set out to resolve. One person I worked closely with when developing the Bravo I LT was Pro Angler Chase Parsons. Ironically, Chase also runs a 21-foot Nitro ZV like our test vessel. Chase opted for a 350 Verado to power his rig.

“I ran the Bravo I LT for the first time in my last tournament under smooth conditions. The LT is very impressive,” said Chase.

“For me, the Bravo I LT provides the best results in both smooth and rough water.” Pro Angler Chase Parsons.

“I was seeing 62 mph under a full load with a big co angler and 63.7 mph on the way in after burning 25 gallons of fuel and filling the live well. The engine was turning 6190-6280 rpm at both speeds.  “I feel confident I will see over 65 mph easy with the right conditions,” Chase said.

Chase recently has had some rough water experience with the LT.

“When comparing it to my 3-blade, the 4-blade Bravo I LT definitely is better with keeping the bow from hopping, improving the overall ride and handling. So for me, the LT provides the best results in both smooth and rough water,” said Chase.

Pro Angler Tom Bauer

Our Blog has proven to be a valuable resource for our customers and for us.  Believe me, we learn tons in responding to the various questions that come through. Tom Bauer had recently written me asking for help in dialing in his 2016 Ranger 620FS. Tom was very specific with the engine speed and boat speed he was seeing with the prop the boat came with as well as test data collected from aother prop he had tested.  I think Tom was surprised when I contacted him. Seeing he lived in the area, I offered to spend a day to test props with him. A prototype Bravo I LT was in the mix of props provided for Tom to test.

“During my prefishing for the Cabelas National Walleye Tour Lake Winnebago, I provided Scott feedback and he stopped out one morning at the landing to drop off additional prototype props based off of my feedback.  My experience with Scott and Mercury Racing will not be forgotten, the commitment to service and research and development, teaming with Mercury Pro Team members really makes me feel like I am part of a family of an excellent company who is “Number One on the Water,” Tom said.

The prototype Bravo I LT created more bow lift which in turn enhanced engine RPM for greater top-end speed and improved boat handling.  All this without sacrificing hole shot or load caring capabilities.

Toms Rig:

  • 2016 Ranger 620FS
  • Mercury 250 ProXS with hydraulic Atlas jack plate
  • Bottom of cavitation to floor is 17.50 inches
  • Bottom of hull to floor is 14.25 inches
  • Cavitation plate is 3.25 inches above boat bottom
  • Mercury 9.9 ProKicker (Remote)
  • 4 – AGM weight (80lbs each)
  • MotorGuide Xi5
  • Full tank of fuel
  • 2 guys over 200 lbs. each
  • Full Tournament Load

Bravo I FS VS LT Test Results

  • 21″ pitch  Bravo FS:  55 MPH @ 5700 RPM (Difficult to steer – bow heavy)
  • 21″ pitch Bravo I LT 59.9 MPH @ 6190 RPM (Bow lift was amazing and the boat handled well at speed)
  • 22″ pitch Bravo I LT 58.6 MPH @ 5960 RPM (Bow lift was amazing and the boat handled well at speed)

The Bravo I LT features the Mercury® patented Performance Vent System® (PVS).  PVS enables operators to dial-in their propeller for peak planing performance. The PVS® system works in concert with the LT’s robust blades that are hand blended and balanced by our propeller lab artisans.

A majority of Mercury Verado® and Mercury Pro FourStroke applications will use the Bravo I LT with all four vent holes plugged with solid PVS fittings. OptiMax 2-stroke applications require all four vent holes to be open. Upgrades from the Bravo I FS to the Bravo I LT require no change in pitch size when matching engine rpm.

The Bravo I LT is a available in a total of 15 pitch offerings, ranging from 20” to 27.5” in one-half inch increments for precision matched performance for both 2-stroke and 4-stroke outboards.

  1. Got a Lake and Bay BocaGrande Kevlar hull and deck lids. 05 Merc 250 s. Trolling motor and 3 batteries up front. Another grp 31 for starting. 40 gallons of fuel and all the stuff to fish can run 68-70mph gps with Bravo 1 s 25P 4 vent holes.

    What performance benefit will this prop provide?

    Thanks
    Mitch Newton

    1. Mich,
      The added tube length should offer a little quicker planing along with added bow lift. This will enable you to carry the weight of the batteries. It’s hard to say what will happen with top speed, however, because the barrel length, it could add or scrub top speed by 1.5 mph. You know how the Bravo I FS rides or lifts; looking at the LT plan for it to pick the stern up higher than the FS. Maybe your boat would benefit from that added lift.
      Scott

  2. I have found that the Rev 4 gives the 620 ranger/verado better bow lift then the bravo 1 FS. How does the new bravo compare to the Rev 4?

    You can respond here for everyone to see but would like to talk to you through email if possible. I have a very specific boat, not really similar to most peoples.

    Thank you, Gary

    1. Gary,
      The Rev 4 is a great prop and, in your case, it can offer added bow lift depending on how the boat is loaded along with engine height. If the Rev 4 was used at the 3-blade engine height, you’ll get added bow lift generated by the long barrel. The problem is pitch. If you started with a 21” pitch Tempest to achieve the same engine rpm – you would drop down to a 19” pitch Rev 4. This equates to a loss in speed and fuel economy. When moving from the Rev 4 to the Bravo I FS or LT, we recommend going up 1.5” to 2” of pitch to get the same rpm as the lower pitch Rev 4. More pitch – more speed. The height of the engine is critical for multi-species boats to achieve optimal performance. By raising the engine, drag is reduced with less gearcase flowing through the water. At the higher levels – the Rev 4 shouldn’t generate as much bow lift which is why we have the Bravo I LT. If your set up is heavy in the front requiring bow lift to get good speed, then you should benefit from flare of the LT barrel. The flare defects water up, down and sideways. The larger, heavy boats benefit from the water deflecting down – offering stern lift. The water deflected to the sides benefits the heavy boats for turning and the water deflected up can create added bow lift. As the water flows past the gearcase into the propeller, the water is deflected by the flare sending it out which produces leverage. The downside of the flare, on some applications, is it can cause drag on lighter boat applications. For example, on a 206 Triton with 250 Verado, the LT – when compared to the same pitch FS – will slow the boat down 1.5 mph at WOT and cause too much stern lift; negatively impacting handling and ride.
      Scott

      1. When comparing the two props, you are assuming the same slip numbers, correct? It seems that the Bravos have a higher slip number so the pitch for pitch comparison isn’t totally relevant is it?

        1. Neil,
          The Bravo I FS and LT run light or low in pitch compared to other Mercury propellers. However, between the two Bravo’s – I would use the same slip numbers.
          Scott

  3. Interesting results from the examples given. The Nitro only achieved a 10 RPM gain from the FS to the LT similar pitch props, whereas the Ranger almost 500 RPM. I realize they’re different boats but that’s a significant difference. Curious as to your thoughts on why the significant increase with the Ranger.

  4. scott I have talked to u before about my 28 bravo 1 xs on my 2012 z8 250 pro xs, im happy to say the 27.5 bravo1 xs I purchased sold the 28 is a better performer so im happy, this new prop looks interesting and my boat likes more stern lift will this prop do this and will it perform rpm wise to the 27.5 I currently have,r they pitch to pitch compatible and what is the price of this prop and availability any chance of trying one. thanks

    1. Samuel,
      Glad to see you like the 27.5” pitch Bravo I XS. If your interested in the LT, these props run pitch for pitch and the price is a little less than the XS. The LT has just 4 vent holes but – with the help of the longer tube – it should be enough venting to plane the boat.
      Scott

  5. Scott,
    I got my 23.5 pitch last week and tried it on my 219 Yarcraft/ 350 verado. this prop is made for heavy loads. ( and last time i looked in the mirror , it must be for me) . It picks the boat up on plane and up to cruising speed faster than the 23 Bravo FS. and carries more speed in mid range cruise.

    23 BRAVO FS

    3500 RPM’S = 35 MPH
    6300 RPM’S – 63.5 MPH WOT

    23.5 BRAVO LT

    3500 RPM’S = 37.5 MPH
    6210 RPM’S = 63.5 MPH and gets there quicker than the FS prop

    I still have trim left , but it looses bite and starts slipping and at 6320 rpm’s it has dropped to 61.5 mph. Not for sure yet , but it seems to be quieter at cruising speed with the longer tube. Over all i think this is going to be a better prop for my boat. Although i was hoping for 2 mph on the top end , actually how much time is spent at WOT compared to mid range cruise.( it is noticeably better in mid range).

  6. Scott,
    I have a 2008 Ranger 620VS in high elevation, (3600ft), with a 250hp Pro XS Torquemaster Gen I and a 9.9 Kicker no jackplate. I am looking for a prop with better hole shot and top speed. I am currently running a stock 19P Rev 4 with all PVS plugs removed (prop doesn’t blow out with the PVS completely out). Full of fuel and 2 people I am getting an average of 50mph @ 5800Rpm in a 6000ft Dynamic Altitude.

    After moving the motor to the top hole I am seeing 5925RPM at 50.5mph on the stock 19 Rev 4.

    I have recently tried a modified 22p Bravo and was seeing 53.2MPH Full Fuel, 4 31 Series Batteries, 2 175lb guys, all gear, 9.9 Kicker, and 101 Terrova at 5560rpm on Flat Calm water (83* Surface Temp) in a 7300FT DA.

    Would going to the 21 Bravo LT or 21.5 LT yield better results for my high elevation and Dynamic Altitude battle with my 2 stroke??

    1. LJ
      Raising the engine increased the prop slip reducing the efficiency of the prop. Check the measurement from the cavitation plate to the bottom of the boat. The average is 2.5” to 3.5” when running a 4 blade. Park the boat on level ground. Hold a level up to the boat bottom – toward the transom. Use the trailer jack to adjust. Now trim the engine down and place the level on the anti-cavitation plate. Take a measurement from the bottom of the cavitation plate to the floor and subtract the boat bottom measurement from the floor measurement to get the 2.5” to 3.5”. If your engine is higher than that the zone you may want to bring it down and go with the 21” pitch LT. If it’s in the height zone and you were getting 5925 rpm with the Rev 4 then look at a 21.5” pitch LT. The modified Bravo I can’t be use as a reference prop because we don’t know what was done to it. Have fun with the LT.
      Scott

  7. I want a Tech to Help with my UpGrade to a 4 blade Bravo 1 LT . From my Laser 2, 23 pitch Fully Loaded WOT at 4600 . 60 MPH. My set up is Ranger 395V1/O
    350 MercMagnum Alpha One 1991.

    1. Thanks for the call in. During the call we both decided on the 23″ pitch Bravo I LT because of the low 4600 rpm. Running the 23″ pitch will offer an additional 100 to 150 rpm – resulting in better all-around performance.

      1. Scott,
        Thanks for all the Tech Help,
        One more question if I could ?
        The Torque setting with that Cone tab inside the Hub,
        install with that is 100L:bs.
        Without it is 55 Lbs.
        I did as it said, 100Lbs. but there is NO-Way my
        MERC floating Prop wrench can handle that for an
        Emergency Prop swap. Any thoughts ?
        Can’t wait to get to the Lake for Demo.
        Then on to the Ca.DELTA.
        Thanks Again Scott and Jaco marine.
        Kelly Mark Hensley

        1. Kelly,
          The plastic wrench is for emergency use. You’ll require a proper torque wrench to achieve the recommended torque specification.
          Scott

    Currently running a 25 pitch Rev 4 stock. What will be the correct pitch to go with on the Bravo LT to match the same Rev 4?

    Thanks
    Phil

  9. I am currently running 22 pitch bravo1 prop on my 2015 ranger 620fs. Alone in my boat I can hit 60mph but with 2 people in the boat I have a real hard time getting up on plane. Would a 21 pitch bravo 1 lt be a better prop for my situation

    1. Bill,
      If you’re running the 22” pitch stock Bravo I, move to the 21″ Bravo I LT. It will greatly improve planing with the heavy loads. Plan to pick up 200+ rpm.
      Scott

      1. Thank you for the reply. you told me to expect a 200+ rpm increase on the 21 pitch bravo1 lt. That would overrev my engine. With the 22 pitch bravo1 fs i am turning right at 6230 rpm by myself in the boat. Really trying to get it right this time. do you think a 21.5 pitch bravo 1 lt would give me better hole shot yet keep me around the 6400 rpm. I would really appreciate a reply.
        Thanks Scott
        Bill Anderson

        1. Bill,
          No problem, happy to help. The LT and FS should achieve the same rpm at WOT. I agree, the LT for the 620 FS should be the better of the two. So, if you run the 21.5” pitch LT the rpm should split the difference between the 21” FS (6450) and 22” FS (6250).
          Scott

  10. I have a Lund 2075 ProV w/300 Verado Pro with 21 Tempest. My rpm at wot are around 5800, speed is good at 58 mph. Hole shot is decent. I would like to see the rpm up a little maybe 6100 – 6200, and maintain top speed and hole shot, what pitch Bravo 1 lt should I look at?

    1. Kevin,
      Run the 21″ pitch Bravo I LT and make sure your engine is at an appropriate height. The importance of engine height is described in our FS Miller blog. The cavitation plate should be near 2.5” above boat bottom to achieve maximum performance. Your engine speed will increase to 6200 rpm – resulting with improved overall performance – from planing to wide open throttle. Enjoy.
      Scott

    2. Scott is dead on here. After raising my 250 Verado up 2 holes on my 2075 Pro V my rpms went from 5840 to 6180-6250 and speed at WOT gained 2.3mph with the factory 21 Tempest. I was pretty excited to see my new 21″ FS on the doorstep today until I saw there was a new bravo released.

      Seems the single best thing you can do to improve the performance of a Lund 2075 ProV/Verado pro is fix the engine height.

    1. Samuel,
      The LT works for both two and four stoke. The two stroke will primarily use 20” – 22” pitch. The four PVS holes, coupled with the longer barrel will enhance your planing performance. Setups that need higher pitch will primarily benefit more the XS.
      Scott

  11. I have a 2015fs and hole shot is poor with 3 people. I tried a22 bravo and didnot gain a thing. I am currently running a 21 rev 4 , what would you suggest ?

    1. Dennis,
      What engine are you running? Also, what prop style and pitch did you start with and what was the rpm and speed at WOT?
      What style 22” pitch Bravo I?
      What are you getting for rpm and speed with the Rev 4?
      Hopefully your data is with 3 people.
      Scott

  12. Scott I have a 2013 Tyee 186GL with a 200 verado L4
    Currently running a 14×19 Enertia. 48mph @6200 rpm and low end doggy out of hole. seems to porpoise badly. I tried a Rev 4 19 pitch per Dealer recommendation. Results were just as bad hole shot and lost top end 5700-5800 at 45-46 mph. but I liked the handling of the 4 blade at crusing speed and full throttle. My motor is set one hole from top and measures approx 1″ from bottom of boat. Any suggestion s on the Brovo 1 Fs.
    Thanks Dayne

    1. Dayne,
      If your engine’s AV plate (anti-ventilation plate) is only 1” above boat bottom, that could be the source of your performance issues. Consider raising the engine so the AV plate is 2.25” to 2.5” above boat bottom, (each transom bracket hole measures .75”). If you still have the Rev 4, run it at the new height to see how the boat handles. If you don’t have the Rev 4 then look at the 20” pitch Bravo I FS (but only after the engine has been raised). Enjoy. It will be like the way you would expect your boat to run.
      Scott

  13. I have a 2017 620 fs with 250 verado. What would be better overall performance the 3 blade or 4 blade? Currently have 4 blade bravo 1 22 pitch

    1. Giannis,
      The comments are for a single engine outboard set up. For the most part, they match rpm pitch for pitch. However, if the LT can allow for a little more bow lift (and it depends on the boat set up) then the LT may generate up to an additional 75 rpm. The LT is designed to offer added bow lift with forward CG boats or bow heavy boats. Boats with the CG near the driver seat or aft typically benefit from the FS. The stern lift from the LT supports the big, deep, heavy boats or, for an example, a second small motor on the transom for trolling. For example, I have a Triton 206 with 250 Verado. The Bravo I FS is 1.5 mph faster and handles much better than the LT. The LT offer too much stern lift for my boat.
      Scott

  14. Currently running a 2010 opti 200 with a 21p tempest and getting 5200 rpm and 54mph switched to a 19p tempest and getting 5450rpm with 54mph. What pitch bravo 1 LT would be best?

    1. Jason,
      To determine which style to go with (FS or LT) let me know what boat you’re running and how it’s loaded. Also, can you check how high your AV (anti-cavitation) plate is above the bottom of the boat?
      Scott

      1. Sorry just seen your response now. Boat ia a 2010 lund 1975prov loaded with tournament load. Also have a 9.9 pro kicker on rear.Av plate is 2.25 above bottom hull.

        1. Jason,
          I’d like to see the engine rpm come up. I’ll suggest the 19.5” pitch Bravo I LT. The rpm should come up to 5500 to 5550. Hole shot will be awesome and top speed might surprise you – with a gain of 1 to 1.4 mph.
          Scott

  15. Hi Scott
    Thank you for the return of my first post. I feel I need to give you a little more info. My boat is a 2015 620FS with a 250 Verado, 9.9 Mercury kicker with remote and a minnkota talon on the back. Currently I am running a Bravo1 FS prop 22 pitch. In the right weather conditions I can run 60 mph and 6250 rpm at wot. The problem is with 2 people I have trouble getting on plane. I have tried a Bravo1 FS 21 pitch and it gets on plane real good but at times I noticed 6450 rpm. It never hit the rev limiter but I thought my engine wasn’t supposed to exceed 6400 rpm. I am wondering if a 21 pitch bravo1 LT would be the same rpm or do you think the 21.5 pitch would still be better on plane than the 22 pitch and maybe stay closer to the 6400 rpm. I just want to get it right this time. I have tried a rev4 19 pitch but run 55 max at 6140 rpm. Thanks for any input

  16. Hi Scott
    I posted an comment earlier but think I need to give you a little more info. My boat is 2015 ranger 620FS with 250 hp Verado and 9.9 Mercury kicker with remote. Also have minnkota talon on transom. Currently running 22 pitch bravo1 FS prop. Run with right weather conditions 60 mph at 6250rpm Problem is slow getting on plane with 2 people. I have tried bravo1 FS 21 pitch. That really helped getting on plane and only lost 2 mph at wot. Problem is I was turning 6450rpm. It never hit rev limiter but know my engine says 6400 rpm max. Have also tried 19 pitch rev4 prop but only run 55 mph and 6140 rpm. Do you think the new bravo1 LT prop in a 21 pitch will be better or should I go with a 21.5 pitch. Any input would be greatly appreciated. I just want to get it right this time

    1. Bill,
      Thanks for the additional information. I think you’re spot on with the 21.5” pitch. The LT would be the direction to go.
      Scott

  17. Scott, I am running a 2011 175 Verado on a 2011 Ranger Reata. Currently running a 19 pitch rev4 at 6400 rpm and seeing 50 average, low 50’s with right conditions. Motor has been boosted by Simmon. Overall fairly happy with performance but like everyone always wonder if I can get more. Would a Bravo FS or LT improve top end or overall performance? If so which would you recommend and what pitch. Thanks!

    1. Wayne, the 19″ Rev 4 is working really good and we have had some great results with the Bravo I FS. However, I think the Bravo I LT might offer even more. If you get the chance to run the 21″ pitch Bravo I LT, it appears you should pick up 2 to 2.5 mph.
      Scott

  18. Have a Lund 219 pro v gl with a Merc 350 Verado. My first prop I tried was a Bravo 1 FS 21P. Then I tried a 20P Rev 4 and now I’m running a Rev 4 19P modified with added cup and a few other things. I’m having porposing issues. I’ve added weight up front to try to distribute weight differently – still no help. This occurs by myself at WOT. Any suggestions?
    Thanks

    1. Joe,
      Move to the Bravo I LT the added length and flare of the barrel should take away the porposing by providing added lift. If the 21 FS offered the right rpm stick with that pitch but if you need a little more rpm the 20.5” should give you 75 to 100 and the 20” 150 to 200.
      Scott

  19. Hello Scott, I’ve got a new to me 14′ Ranger Reata 1850LS with a 175 ProXS (WOT=5,250-5,750rpm). I’m wondering whether or not a Bravo 1 LT 20P? might improve my over all performance from a PowerTech RKR4 18P 47.6mph@5,700rpm.
    Tempest 21P was 45.6mph@5,340rpm; Rev 4 17P 45mph@5,630rpm; Rev4 19P 49mph@5,360rpm; Trophy 19P 50mph@6,200 rpm (Too high)
    Thanks much.

    1. Todd,
      The layout of the Reata puts a fair amount of weight forward of which the LT was designed to combat by offerig additional bow lift along with a little stern lift. The 20” pitch should be spot on.
      Scott

      1. Hello Scott,

        With Spring close at hand, I’m was getting ready to order up the LT 20″ for my Reata as noted in my earlier request.
        I see since last fall you guys have added a 19″ & 19.5″ pitch to the catalog.
        Based on my earlier information on the boat, do you still feel I should try the 20″ Pitch or go a little lighter, say 19″ or 19.5″?

        Thanks,
        Todd

        1. Todd,
          Glad you continue to read up on the LT, while I think the 20” would be good I think the 19.5” would be even better. If we can give your engine a little added rpm I think you have the best over-all performance from planing to WOT speed. Enjoy!
          Scott

  20. Scott I am running:

    Legend 191 w/175 Proxs ( Boat is a bit rear heavy gas tank is in the back)
    3.0 prop to pad
    21 P Bravo 1 FS

    Tournament load 5750- 5800 rpm 54 mph (5000 ft)
    Solo lighter load 5900-5950 rpm 56 mph (5000 ft)

    Do you think the Bravo 1 LT will give me any benefit ?

    Thanks

    1. Mike,
      That’s a tough call. The FS is hooking up extremely well. The long tube acts an extension of the gearcase – providing added stern lift. It might be just enough for your Legend.
      Scott

  21. Hi Scott, I am running a 1999 Triton 205 with a 1999 225 optimax, with the stock 23 tempest I am turning 5800, but need a better hole shot. What pitch should I run in the LT? Thank you, Rick.

    1. Rick,
      Comparing to the 23” Tempest, a 24” LT would achieve similar rpm. To take full advantage of your rig with a 4 blade Bravo, consider raising your engine so the AV plate (the plate above the prop) is 2” to 2.75” above boat bottom. I think the Bravo I FS will run better on your 205 – hands down! It works better on the 206 with ride, cruise, boat handling and top speed.
      Scott

  22. Scott- I am running a 21p bravo1fs on my 2015 300verado pro mounted on my 2015 621 Verado pro 300. No jack. with the 21p I run with 2 guys tourney loaded 5750 to 5850. Would the LT help top end?

        1. Tim,
          For your current set up I would move to the 19.5″ pitch Bravo I LT. You will have more torque with the lower pitch prop so planing will be better and speed should be comparable. I have a feeling the engine is mounted low. If the AV plate is level or only one-inch above the boat bottom, consider raising the engine so the AV plate is at least 2.25” above boat bottom. If you raise the engine; re-test with your 21” pitch FS. It may be right on.

  23. Scott, I’m running an Alumacraft 205 Competitor Le, 250 Pro Verado with a 21 pitch Rev 4. Current numbers are 55mph @ 6050 Rpms loaded. Good handling, good hole shot. Looking for some more top end speed for some of these walleye tournaments! Could anything be gained with a bravo 1 or lt?

    1. Bill,
      Nice rig! For the lighter weight, multi-species boats consider the FS instead of the LT. I’m positive you’ll get a great hole shot, better ride, increase mid-range fuel economy and faster top speeds. The lighter boats should see increased stern lift with the LT, scrubbing speed and lowering the ride quality. To achieve similar rpm as the 21” pitch Rev 4, run the 23” pitch FS;.Speed could pick up 2 to 2.5 mph. Tip, if your boat feels like it’s stuck to the water at half to WOT throttle look at the engine height. the AV plate should be at least 2” to 2.75” above boat bottom. For more information on the Bravo I FS read Brian’s Experience.

  24. I have a 2016 Lund 2175 Pro V with a 350 Verado with a FS1 20.5 on it now but am disappointed at topend being only 58 mph with 3/4 fuel and 2 guys. max speed is at 59-6000 rpm starts slipping after that. Was looking at maybe Bravo LT 22p or higher? What would you suggest? Thanks for any help on this!

    1. Steve,
      This might be a height issue. How many inches is the AV (anti-ventilation or cavitation) plate above the bottom of the boat? On flat pavement, with the boat on the trailer, hold a level and adjust until the boat is level. Then record the distance from the very bottom (right in front of the engine) of the boat to the pavement. Trim the engine down – until level (place the level on the plate to check). Measure the distance from the bottom of the plate to the pavement. The plate should be a minimum of 2” above the boat bottom. Let me know.
      Thanks,
      Scott

  25. Scott,

    I have a 2015 Ranger 621VS , with a 300 etec. I’m running about 54mph @ full tourney load @5400 rpms. It has the stock 3 blade 15×21 on it . Would you recommended the new lt or bravo Fs and what pitch . Thanks Charlie

    1. Charlie,
      It’s probably better for your motor to rev up a little higher. Consider the 21″ pitch and with that size of boat – run the LT.
      Scott

  26. Scott,

    I have a 2015 Ranger 620FS with a 250 Yamaha Offshore, 6″ Powertran jack the pro edge fin running 62MPH @ 5800 RPM’s on a 21 Tempest. 20.5 Bravo at 61.6 MPH @ 6000 RPM’s. I know I can step up my max speed with the Bravo LT in 21″ would it be a gamble to get a 21.5″? What would you suggest?

    1. Zach,
      Nice set up. I wish you had a Mercury on the back but hey; we appreciate you running Mercury propellers. I’m leaning toward the 21.5” B1LT which should put your engine speed at 5850 to 5880 rpm. Your speed should average out to 63 mph.
      Scott

  27. I have a 2200 te pathfinder with 250 sho running a 22 p bravo 1 with cut can 5800-6000 60mph to 63 mph on normal loads will this help me I cut the can off for bow lift I am kinda lost on the Ltd having more lift then the xs or fs ran a 23 fs at 65mph light load

    1. Dustin,
      The Bravo I LT is a long tube version of the Bravo I FS. Some set ups will benefit from the longer tube but – in your case, it’s too hard to tell because you’re achieving impressive numbers with the 23 B1FS. If you could try a LT, consider the 22.5” pitch.
      Scott

  28. I currently have a lund 202 gl with a 300 pro. I currently have a Bravo 1 fs with the motor as high as it will go without adding a jackplate. I currently am running 6200 rpm wot, 61-62 mph. I am unhappy with the hole shot. With a full livewell, 1/4 tank of gas and two guys I struggle to get on plane. Wondering what your recommendations would be? I had a entertia 19p, 6,300rpm 59-60mph but I was having some porpoising issues at higher speeds.

    1. Josh,
      If you’re running the Bravo I FS in 20″ pitch, switch to the 19.5″ pitch Bravo I LT. Planing will greatly improve because of the lower pitch and the longer flared barrel. The LT’s longer barrel acts as leverage for bringing the boat on plane. Top speed should be the same.
      Scott

  29. Hi Scott,
    Just picked up my new 2016 Lund Pro-V 2075 with a 300 Verado Pro. At wot the engine is getting 5850 rpm and 54.5 mph with a med/heavy load. The engine is mounted in the second position and the Cavitation plate is level with the bottom of the boat and is equipped with a 19p Tempest. I would like to maintain good hole shot, quick planing, increase rpms and top end speed. What is your recommended set up. Thanks.

    1. Jerrod,
      Please read our blog post, FS Miller. Check out the before and after performance numbers. If you do the same things we did with Steve’s 2075 you’ll think you got yourself a new boat! The ride is so much better and speed can’t beat it. If you have a kicker hanging on the transom, then I would recommend the same engine height as Steve’s. For you – I would recommend switching to the Bravo I LT 20” pitch. The LT propeller offers a little more stern lift which will support the added weight of the kicker. Enjoy!
      Scott

  30. I have a 2016 a 2175 Lund Pro-V with a 350 Verado, 15 Pro kicker, Minn Kota ulterra 36 volt motor, five big batteries, 500-700 lbs of human beings, and probably 150 lbs of other equipment and up to 60 gallons of fuel. I have been turning a 21 pitch bravo one FS at around 6200ish RPM’s for approx. 57 mph. My cavitation plate is well out of the water at WOT, I did the plate to boat bottom measurement as suggested in previous posts and the plate is 1.25 in above , but I can just barely get the prop to slip at max trim. I recently tried a 22 Bravo One LT that seems to make the boat ride higher in the water allowing me to be able to slip the prop around 8 on the trim level, I could turn the LT approx. 6000 RPM for approx. 57.5 MPH. I would like to try a 21 LT Bravo which I will assume I will be able to turn around 6200-6300. My question to you is should I raise the engine one hole and start over testing props? I hope I have provided you with enough information. Thanks in advance for your time. Hank Tashjian.

    1. Hank,
      Yes. consider raising your engine two holes – making the AV plate 2.75 inches above boat bottom and re-test with your 22 LT. By raising the engine, a gain of 200 rpm could happen which would allow the engine to hit the sweet spot. This should offer another 2 mph.
      Scott

  31. Scott,
    I’m running a 2016 Ranger 621 w/250 Pro XS and a 22 pitch Bravo XS.
    top speed 54 alone and full tank of gas. Hole shot is decent, Happy with this set up but looking for any thoughts on if the LT will help this rig?
    Thanks
    Mark

    1. Mark,
      You’re going to like the Bravo I LT. There will be a noticeable performance improvement. When Ranger moved the consoles forward with the FS models that changed the CG (Center of Gravity) adding additional weight toward the front of the boat. In the past, the lightweight of the Pro XS was thought as a performance benefit compared to the Verado. With the FS hulls, more weight on the transom generates more bow lift so the added weight of a Verado would outperform the Pro XS. You can get that performance back with the Bravo I LT. The added barrel length and flare will help generate bow lift. As the engine is trimmed out and water passes into the gearcase, the pressure of the water creates a downward force onto the top of the gear housing where the prop shaft is located. The water flows from the gearcase into the prop and the longer barrel and flare deflect the water even more offering added bow lift. If you need to generate added rpm, a 21” pitch should offer another 150 rpm. Enjoy.
      Scott

  32. Hi Scott,
    I’m running a Lund 2175 Verado 350 with a 21p Tempest Plus at 6000RPM +or – 75rpm depending on water condition and fuel load at 60 mph. Will this prop help me get the other 300 to 400 rpms and pick up any speed. I have not tried moving it up a set of holes yet but am at a solid 2 inches above the bottom that I noticed you mentioned in other posts.
    Thank you,
    Mike

    1. Mike,
      The larger gearcase used with the 350 and 400 Verados enable the engines to run 1” higher than the optimal height for the 300 Verado which features a smaller gearcase. At the current height, a 21” pitch Bravo I LT should pick up 150 rpm which is a good rpm range for the 350 Verado. The speed should increase to 1.3 mph. Most liekly the biggest gain is the improved ride and boat control the 4 blade provides over the 3 blade.
      Scott

  33. Scott,
    I have few questions about the Bravo 1 LT vs FS. I have a 206 Triton Fishunter with 250 Verado Pro that started with a 22″ Tempest. Although the top seed was good, it was slow getting on plane, handing and ride was not great. After some advise I switched to a 23″ Bravo 1 FS, which I ran out of season to really get things dialed in. But the little bit I have played with it seems to really have improved the planning time and handing while maintaining speed. All of which are all good and can’t wait to play around more in the spring. But now I am little curious about the Bravo 1 LT, and wonder if would it make much of a difference over the FS. After reading through some of the questions and feedback you have given to others, it looks as though you might have already tried both of these props on this hull motor combination. If so can you give me your input on the differences, and also maybe and idea of engine height. Thank you for any information you are willing to provide! I also continue to enjoy the fact my Verado is faster then my brother inlaws new Evinrude 250 G2, go Mercury!!

    1. Adam,
      Thanks for the question. Hands down, the Bravo I FS is the better choice. The LT is geared toward rigs that are slower and heavier and in most cases running a deeper hull. Last summer I tested the LT and FS on a 2016 206 with 250 Verado Pro. With an assortment of LT and FS pitch props, the best performance was with the AV plate 3.5″ above boat bottom running a 24” pitch FS. I achieved 64.4 mph @ 6000 rpm. The boat was loaded with gear. The fuel tank was 3/4 full and we had 2 adults (360 lbs.) on board. The LT picked the stern up too much; scrubbing 2 mph. The boat didn’t ride as good. It fe;t like it was stuck to the water. Have fun rubbing it in with your brother-in-law.
      Scott

  34. Scott,

    Do you guys have numbers for the 21.5p LT on a 620FS with 250 Verado with kicker? No jackplate. Currently running a worked 19p rev 4. 56 mph @ 6100 rpm loaded. Would I be better off running the LT? Thanks!

    1. Roger,
      Sorry I don’t have any numbers now. I can ball park it. A 21” pitch should achieve similar engine rpm as the Rev 4 with an increase of 1.5 mph.
      Scott

  35. I always have a hard time with what is considered a lighter boat. I run a 2025 pro v and my guess is with the 250 verado on the back, batteries etc it comes in around 2,800lbs or so. Is that considered light or heavy? I run a 21p tempest and while overall the performance is good I’d like to get to a 4 blade prop. What would you recommend I try the FS or the LT?

    Current performance: I shoot out of the hole and run about 55mph at 6,000 rpm wot.

    1. Bill,
      If on average, you run with 2 people on board I think you’d be good with the 21” pitch Bravo I FS. However, if you run with 4 people on board (200 pounds plus each) along with a good amount of gear and a kicker then you will want to go with the 21” pitch Bravo I LT. You should also check your engine height. In most cases, Lund mounts the engine’s gearcase AV plate 1” above the boat bottom. Consider raising the engine 2 holes to maximize the ride and performance of the rig while running either Bravo I.
      Scott

  36. Hey Scott, Im running a 400 R, I can turn a 22 bravo fs with added cup ad 7050 and 72.8 mph, Do you think thr bravo LT 23 get me a bit more out of this, I tried a 21 rev 4 shaved and added cup bymyself I hit 73.9 at 7060 rpm, I wanna bring my rpms down, I will be lighting my boat load up by 300 lbs next year also, the bravo likes to run high on jack plate and can take lots of trim unlike the rev 4 like not near as much trim and jack plate, I did turn a bravo 24 but got porpise, it hit 73 mph max and just didn’t feel right, What you think I should try here.

      1. I Ran a new out of the box Bravo 24FS, Along With a 23 FS, I am interested in the LT but don’t wanna try a bunch to get it right as there a custom order,

        1. Ryan,
          Plan for pitch for pitch so if the Bravo I FS 23″ pitch gave you the right rpm then try the 23″ pitch LT.
          Scott

    1. Jeff,
      Run pitch for pitch to achieve similar engine rpm. However, the LT’s longer exhaust tube may offer too much stern lift. The LT is equipped with (4) vent holes and your XS has (8). You may require all that venting. The lower the pitch the less venting is required. I’m not sure if (4) PVS holes is enough for your set up.
      Scott

  37. Scott,
    I have a Nitro ZV21 with a Merc 250 Optimax turning a Tempest II. I want to get more lift, and holeshot for Lake Erie.
    My question is with a current 21′ pitch would I see a little more lift from a Bravo FS in a 21.5″, or stay with the 21″.?
    I plan to move up in HP to a 350 Verado next fall, My question here is a 21.5″ Bravo usable on a 350 Verado, or a bigger pitch needed.?

    1. Edward,
      If you’re running the 21” pitch Tempest Plus, the general rule of thumb is to move up 1” of pitch to a 22” pitch Bravo I FS or LT to achieve similar rpm. To gain the maximum performance, your engine may need to raise up so the AV plate is at least 2.5” above boat bottom. Most ZV21 set ups today are using the 4” jack plate to achieve the best performance. Raising the engine for calm to chop for maximum speed and lowering the engine for better boat control on water that Lake Erie can throw at you. I spoke with Chase Parsons at the Minneapolis boat show last Saturday and he recommends using a jack plate with the 350 Verado on his ZV21 Nitro. The best prop for his rig is the 22.5” pitch LT.
      Scott

      1. New Warrior 208 on the way with 350 Verado and kicker motor. Any experience with Warriors? Do you have a prop recommendation? Engine height recommendation?
        Thank you,

        1. Jarrell,
          They had been sending the 208/350 Verado with either the 22” pitch Tempest or the 19” pitch ECO. Not sure if they have had the chance to run the LT. This past October we ran a 208 with a 300 Verado Pro. We had 40 gallons, 5 batteries, a trolling motor and full tournament load (every compartment packed). The AV plate was 2” above boat bottom which is their normal setting. The wind was not ideal; 15-20 MPH and 1.5’ to 2’ chop. The 21” pitch Tempest ran 56 MPH @ 6200 rpm and the 21” pitch Bravo I LT ran 58 MPH @ 6350. Not only was the speed impressive but the ride was far superior. Back to your new set up, the 350 Verado with its larger gearcase performance better at least .75” higher on the transom compared with the 300 Verado Pro with the AV plate 2.75” above boat bottom. If the factory setting for the 350 AV plate is 2” above the boat bottom with the 22” pitch Tempest, move up to the 23” pitch Bravo I LT. If you can go up with the AV plate 2.75” above the boat bottom, plan for the 24” pitch LT.
          Scott

          1. I appreciate your quick response. One thing I should have mentioned is I will be running primarily at 2200+ ft. elevation. Not sure what elevation you tested at. Will that change your recommendation?

          2. Jarrell,
            Elevation doesn’t affect the Verado like a two-stroke. The super charger offsets the elevation up to 5000+ feet.
            Scott

          3. Scott,

            I’m running a Warrior 208 with the 350 Verado. Full tournament load plus 5 batteries, 9.9 Pro Kicker, Vantage, and the Terrova. I’ve got a PowrTran 24V power jackplate with a 4″ setback on the boat as well. I’m a big believer in 4 blades, so I ordered the boat without the stock 3 blade 22P Tempest. Here’s my results from some testing last fall. The boat was loaded heavy, two guys, and 3/4 tank of fuel, which is how I run it 90% of the time. Conditions weren’t ideal, the water was a too calm. (The wind in your testing, with a good 2′ chop, is actually ideal for getting max. performance out of the Warrior hull.)

            23P Bravo FS. 58 mph. Around 6050-6100 rpm. Moderate hole shot. Could lift plate for more rpm but no speed gain. Max mph when slightly trimmed in, the prop would lose its bite and ability to hold the bow up at higher trim settings. Some torque steer on the wheel at all trim settings with plate up.

            22P Bravo 1 FS. 6150-6200 RPM. 58-58.5 mph. Moderate hole shot. (Hole shot with 4 guys in the boat is poor.) Could lift plate for more rpm but no speed gain. Max mph when slightly trimmed in, the prop would lose its bite and ability to hold the bow up at higher trim settings. Torque steer on the wheel at all trim settings with plate up. I have the most time on this prop. It would regularly run at +/- 60mph with my normal load depending on wind/water conditions. I have seen 63 mph with this setup in ideal conditions and a lighter load.

            21P Rev4, worked by DAH Propellor. 59-59.5 mph. 5900 rpm. Slower hole shot than both Bravos. Good handling once on plane. No pronounced bow lift, it lifted entire boat and ran quite flat, excellent bite all the way to max trim. It’s a hard prop to turn! No torque steer.

            I also have a 20P Bravo FS that I wasn’t able to test that day.

            I was going to go the Rev4 route, but based on what I’ve read so far, the Warrior 208 is the perfect candidate for the Bravo LT. I see your recommendation to go with a 23P or 24P Bravo LT above, does my data change your opinion at all? My preference would be to see higher RPMs at WOT and have a better hole shot for rough water days. I’d love to get your recommendation on pitch, because I only want to do this once if possible!

          4. Orrin,
            Thanks for the detailed information. With your heavy load – lean towards the 22.5” pitch Bravo I LT. The Mercury Technical rep tested with Warrior last fall and the LT was the best, right out of the box.
            Scott

          5. Good to hear on the testing with Warrior. I think I just missed having the testing done on my boat at Warrior Fest. There was talk of testing a new prop, but it wasn’t quite available yet for those dates.

  38. Scott,
    I have a 2017 Ranger 621 with 350 Verado on order and am wondering what prop to start with? Boat will have a 6″ hydraulic jackplate and remote kicker.
    Thanks, Trevor

    1. Trevor,
      Ranger is shipping the 621FS and 350 Verado with a 22” pitch Bravo I FS and, in some cases for the lighter loads – the engines are hitting the rev-limiter so they are exchanging for the 23” pitch. I haven’t heard of any 620FS or 621FS running the Bravo I LT yet. But I’m interested. I will be testing the 20” pitch Bravo I LT with Jim Saric the “Muskie Hunter” on his 620FS with 250 Verado Pro. We will compare the 20” pitch BI LT vs the BI FS. Jim doesn’t run a kicker so, without the added weight, the FS may be the winner. My 206 Triton runs better with the FS verses the LT because I don’t have a kicker. After seeing how Chase Parsons prefers the LT over the FS I’m going to point you to the 22.5” pitch Bravo I LT. Let us know what you end up running. Also – if you could share your performance numbers – that would be great!
      Scott

  39. Hi Scott. I purchased a crestliner 2100 raptor with a 350 verado in the fall. Only had it out a few times. The prop that came with the boat was a 21 pitch enertia. Good performance when it was empty when the sales guys were showing it off. 63.5 mph on gps. When I got all my gear, batteries, trolling motor and fuel in it. Was only getting 59 mph at 6300 rpm. Tried a 21 pitch tempest plus and gained a mile per hour at the same rpm but forgot about the pvs holes(didn’t have them plugged as the prop came off my old pro xs) the boat runs very flat in the water, not much bow lift. Is the bravo lt the answer for that?

    1. Jason,
      The Bravo I LT should be awesome with your rig. Move up to the 22” pitch to achieve similar rpm and look at the engine height. Many companies have the engine set with the AV plate just 1” above boat bottom. With your motor, the AV plate should be closer to 2.5” above bottom. Many boats lose speed after getting loaded up with gear. Switching to the LT will get some of that speed back for you. Enjoy.
      Scott

  40. Scott
    I have a Triton 216 Fishunter coming with a Verado 300 pro. If I’m not mistaken the boat comes with a 4″ jack plate from the factory. I really would appreciate your help with sitting up this boat with the right prop to obtain the best performance. Thanks

    1. Randy,
      I appreciate you reaching out. To date, we’ve had the best performance with the Bravo I FS. If you run a kicker and power pole that may change it to the Bravo I LT. If the 216 runs like the 206 Triton, stay with the Bravo I FS. The LT picked the stern up too much, forcing the bow down – scrubbing performance. As far as the pitch for the Bravo I FS, ask the dealer what pitch Tempest the factory recommends and move up 1” of pitch. For example, move up from a 21” pitch Tempest to the 22” pitch Bravo I FS. Enjoy the new ride.
      Scott

  41. Hello Scott,

    here in Europe we don’t have the same boats with US. I have tried several props in my RIB, it’s 8.60 non stepped hull in semi cabin layout and helmsman position at the centre of the boat. The best consumption, rpm, throttle response results came with ENERTIA ECO 18”. The best performance, handling and seakeeping results came from BRAVO 1 FS. The problem was the excessive prop slip when the boat was fully loaded with equipment, gas and water and the top end rpm@wot where at 6100. I have recently tried Bravo 1 LT with light boat and had 6280 and 49.9knots at WOT the weight was 3 adults (300kg) and 200lt of gas. The prop slip was amazingly reduced (from FS) and the seakeeping has been maintained in a very good level compared to FS. I decided to go with Bravo 1 LT 19′ to be on the safe side at summer when the temperatures rise and the weight rises too as the 6280 rpms which i have seen were without 200lt of gas, without boat’s equipment, without water and with 10C degrees. The boat is using bob machine 8” jack plate so i can triy several heights according to the propeller i am using each time. How should i use Enertia ECO 18” and how Bravo 1 LT 19” in outboard height terms? I feel Enertia ECO needs higher jack plate position compared to Bravo FS. What about LT compared to ECO and jack plate heights?

    Thanks in advance..

    1. Giannis,
      Glad we came out the Bravo I LT.There are so many various boat and engine combinations out there. It’s awesome to see the Bravo I LT helps your rig. A 20″ pitch Bravo I LT should offer similar rpm to the 18” pitch ECO. The jack plate height should be determined by you after testing the application. Have fun.
      Scott

      1. Thanks Scott,

        the problem is that here in Greece the dealer is ordering from Belgium Facility through mercury’s system i would say. They do not have direct communication in order to “ask them” in Belgium to order from USA inside the system procedure.

        What they have told me is that they are not seeing the part numbers for 19 and 19.5 into the system (Belgium)

        1. Giannis,
          I confirmed with Mercury International that Mercury Belgium has the props loaded into their system. However, nothing is on order nor in stock.
          Scott

  42. Scott, I was reading your comments. I am wondering if you can help me out with the used boat I just bought. It’s a 24 foot Manitou Explode Tri toon. Motor is 2009 300XS L Optimax. It was shipped with a revolution 4 21 pitch prop and has 4 plugs. We are looking to get an extra prop from Mercury Racing. Can you suggest 1 that will get my engine into the RPM zone it was built for? Current WOT is at 5,000. Could you advise on how to run the current prop with plugs and the new prop that you recommend with plugs? Any help that you can give is greatly appreciated. Our family is new to the boating experience. We load our boat with a family of 5 and enjoy skiing and tubing.

    1. Tory,
      Typically, for every 2” of pitch change – there is a 300 rpm change with your 300 XS. With the engine, currently at 5000 rpm, dropping down 4” of pitch increases engine speed by 600 rpm to 5600 rpm. Add another 2” of pitch and you will see a drop to reach 5900 rpm. The recommend rpm range for your motor is 5400 to 6200. If you like the Rev 4, the 17” pitch would get you into the low-end of the range. The 15”-pitch will get you close to where the engine makes peak torque. The PVS vent fittings are primarily used with the Opti engines. The Rev 4 comes with 4 PVS holes plugged. Removing two opposite of each other should help the Opti engines plane quicker. Save the plugs because sometimes – when there’s too much venting during planing – you may have to put one back in. If you have some reservation about the Rev 4, the 3-blade Enertia is also a great pontoon prop. If you make the switch to Enertia (not ECO) plan on running the 16” pitch.

  43. Scott,
    I have a 2015 Ranger 621FS with a 300 hp Evinrude Etec. I also have an Atlas 6″ hydraulic jackplate that when in the center position, the 300 hp cavitation plate is 3.5″ higher then the bottom of the boat.

    Currently I run a 23 Pitch Rev4 (lab finished). Cruising seems to be good at 3800 rpm and 28 mph, jack plate all the way down and trimmed half way up. Wide open is about 50 mph with 3 people and gear, best with jackplate all the way down and motor trimmed all the way up.

    Do you have any recommendations on my boat setup or prop ? It seemed like I got the same performance with a 23 pitch rev4(stock) but the rpms were reduces by 200. My preference is for rough water and slow cruising vs. top end speed. Does the Jackplate measurements seem correct ? Would a Bravo1 LT be recommended ? What pitch ? Thanks.

    1. Steve,
      I think the Bravo I LT would be the best prop on your 621FS. The 25” pitch LT should offer the same RPM as a stock 23” pitch Rev 4. Every 1” change in pitch usually results in a change in engine speed by 150-rpm. For every ½” pitch change plan for a 75-rpm change. So, a 23.5” pitch LT should offer 225 rpm over the performance of the stock 23″ pitch Rev 4. Your gearcase is a little different than a Mercury so I can’t say for sure where it should be but I would think it would be similar in height to the Mercury. As a general rule, the AV plate on a Mercury can be 2″ to 3” above boat bottom. Bolting on the Bravo I LT will be like getting a new boat. Enjoy.

      1. Thanks for the recommendation of the Bravo 1 LT for my 2015 621FS Ranger with a 300hp Etec. I thought I would provide some more data to help firm up the pitch. With the stock 23″ Rev 4 I got the following results:
        Revolution 14 5/8 x 23″, 4 blade, boat weight that day with passengers, 5 batteries, kicker, full livewell, 1/2 tank of gas is estimated at 4400#.
        Air temp 80F
        RPM MPH
        3200 24
        3200 21
        3400 25
        3600 28
        4000 32.5
        4500 40
        5400 52
        5800 56
        The Etec maximum is 6000 rpm. Are you still thinking a 25″ pitch LT is recommended given the new information? How would the cruising speed/fuel economy differ between the LT and stock Rev4 ? Any predictions on LT top end speed ?
        Any recommendations on where to go to test a LT anywhere between Green Bay and Fond Du Lac or does one have to be purchased ?

        1. Steve,
          Thanks for the detailed information. Typically, you can move two inches up in pitch from the stock Rev 4 to the Bravo I LT. However, if the boat is a little slow to plane, a 24” LT should offer 5950 rpm at WOT. A 24.5” LT will offer 5875 to 5900 rpm. If you have no issues planing, then you want to keep the engine speed near 5800 rpm with the 25” LT. You can try Pamp’s Outboard, Ken’s Sports or Merten Marine (in Oshkosh with several props) to see if they have a test program. Being conservative, it looks like you could pick up 1.5 to 2 mph in the mid-range and 2 to 3 mph at the top end.

  44. Hi scott,

    I am in process of purchasing a 22ft Blackjack with a 250 Sho so unfortunately I don’t have any performance numbers to offer you. I was wondering if you had any Idea what prop I should start with??

    1. Nick,
      It’s between the Bravo I FS or Bravo I LT. I think the 3 blade Saltwater series props come on the engines. The 3 blades offer bow lift. I would suggest going with the Bravo I FS unless there isn’t a 4 blade that they offer. If the boat is a little sluggish to get on plane and requires some stern lift along with bow lift, then the LT has a greater chance. Whatever 3 blade pitch comes on the engine – move up one inch to the Bravo I. If I guessed currectly, I’d think it would be the 20.5” Bravo I LT or FS.

  45. Hi Scott,

    are Bravo 19 LT and Bravo 19,5 LT available in Europe Market? We are asking for the props from local dealer in Greece and they not seem available in Belgium premises.

    Thank you

    1. Giannis,
      The props are brand new but, by now, they should be in their system. Be sure to give them the part numbers so they can order the props through Mercury Belgium via Mercury USA. Let me know.
      Scott

      1. Thanks Scott,
        The problem is that here in Greece the dealer is ordering from Belgium Facility through mercury’s system i would say. They do not have direct communication in order to “ask them” in Belgium to order from USA inside the system procedure.

        What they have told me is that they are not seeing the part numbers for 19 and 19.5 into the system (Belgium)

        1. Giannis,
          I’ve contacted Mercury Belgium making them aware of your request; hopefully we will have a successful outcome.

  46. hi Scott,
    I have a Triton 206 with a kicker motor, 2016 250 Pro Xs, jack plate from the factory.
    I currently have a 23 pitch Tempest Plus, 3 blade.
    WOT is only 5400rpm trimmed out with with a top speed of 62
    What 4 blade prop and pitch would be best for me, for rough water, and for mid range snap, without sacrificing top end?

    1. Tyler,
      The Bravo I XS will be awesome with your boat. The 206 gets too much stern lift with the LT. If you go with a 23” pitch at the same engine height you should pick up 150 rpm. If you can adjust engine height, the 4 blade likes to run at least ¾” higher than the 3 blade. This should offer additional engine speed; perhaps as much as 100 to 150 more rpm.

  47. Scott,

    I have a 2008 Ranger 620vs. The boat set up is 250 Evenrude H.O. with an 8 inch hydraulic jack plate, Mercury 9.9 kicker, four batteries, trolling motor. I don’t have a lot of gear in the boat. Currently I’m running a Raker 22 pitch that came stock with the boat. Getting the boat on plan can be very difficult and in bad waves even harder. In good weather the boat will run 58-60 mph at 5,800 rpm’s, I’v seen 63 but that is rare. I really would like to go to a four blade but I’m having trouble deciding on what Bravo to run. I would love to have better hole shot and top end. Also looking for better boat response in bad waves. Any help would be much appreciated.

    Ryan

    1. Ryan,
      Your comments regarding on-plane performance and your difficulties running in big water incline me to recommend the Bravo I LT. I think the LT’s longer exhaust tube would enable you to pop the boat up on plane while enhancing boat control and handling over big waves. From the Raker, I’m thinking you can move up 1” of pitch. You would do the same moving from the Mercury Tempest Plus to a Bravo I LT unless you have a jack plate. In that case, plane on a 2” increase in pitch with the ability of raising the engine ¾”. Enjoy.

      1. I got the Bravo 1 FS last summer. I have a Crestliner Intruder 22ft with a Verado Pro 250 6″ Jackplate. I’m at 6450 WOT and 58.8mph with just me in the boat. Would I benefit any going to this prop and should I try going up one more pitch? or .5 pitch? I recently added a 9.9 pro kicker to boat also.

        1. David,
          What pitch FS are you running and how does it plan? If you stayed with the FS going up one inch could offer 1.5 mph and lowering approximately 200 rpm; 6200 is the sweet spot so you have plenty of power.
          Scott

          1. I’m running a 22p Bravo FS. The boat has an Atlas 6in Hydraulic Jack Plate so I can play with motor height. After reading a bunch of blogs I wondered if the LT version wouldn’t be a better choice.

          2. David,
            It will depend on the boat, engine and set up. What are you running the FS on? Also, what’s you top speed and rpm?
            Scott

  48. Scott,

    First of all, thank yo for all the information you have provided through this blog. Very helpful. I have a 14 Lund 186 Pro-V GL with a 200 Verado (L4) and running a Enertia 19P. Its rigged with all the tournament gear minus the kicker. During tournaments I run about 48mph @ 6200rpm, hole shot is terrible and I will get some porpoising at mid throttle. The boat also likes to sit down in rough water and a bit of a challenge to keep in on plane at lower speeds. I am also unable to really trim the boat out without prop cavitation, the distance between the bottom of the boat and the AV plate is 2.25″. Bow lift is not an issue as the boat is pretty well balanced. I was looking at going with the Bravo 1 FS 20P but now I’m thinking the LT might be better. I’m looking for all around better performance from hole shot and definitely more topped speed. I appreciate your thoughts on the best propeller choice.

    Dave

    1. David,
      Engine height is ideal for the 4 blade. I’d go with the 19.5” pitch Bravo I LT. I think the LT will offer better planing, allow for the boat to stay on plan at slower speeds, minimize – if not remove completely the porpoising and improve the overall ride. Top speed may remain the same. You could even gain 1 mph. Your boat was on my radar when I was developing the lower pitch LT. Enjoy.
      Scott

  49. Hi Scott,

    I’m running a 2016 Ranger 621 FS with a 300 hp yamaha with a 19 pitch Rev 4 currently. I’m getting 53 mph top speed at 5400rpm but that isn’t trimmed all the way up. I’m losing speed the higher I go.(50mph at 5800rpm) I am considering buying a Bravo 1 LT but would like you advice on which pitch I should get and what I need to change on my set up. Thanks!

    1. Brett,
      Typically. a move up two inches to the 21″ offers the same engine rpm when moving from the 19” Rev 4 to the Bravo I LT. Consider your engine height to see how high the AV plate is above the boat bottom. Ideally, the AV plate should be 2” to 2.75” above.
      Scott
