Extreme Cup

The all new Revolution 4 XC Propeller.

Our new Pro Finish Rev 4 XC prop, designed specifically for single outboard powered hulls, features an “extreme” amount of blade cup. The Rev 4 XC (15″ & 17″ pitch) complements the Bravo I XC (20″, 22″ and 24″ pitch) as a family of propellers featuring an extreme amount of blade cup with a pitch range of 15″ to 24″ in 2-inch increments.

Eric Simmons, owner and CEO of Simmons Custom Boats said, “When we built the Recon hull designed for fishing the ultra-shallow flats and back-waters of the Gulf Coast from Texas to Florida, we needed a propeller that could deliver instant hole-shot grip, stay hooked up while maneuvering in very shallow waters, and still yield great top end speed.  I knew Mercury Racing could help us get “Dialed In” with this request. The result was the Bravo I XC. This prop design is based on the Bravo I, what is possibly the best all-around prop used on other SCB models. The XC version is unique with very aggressive cupping,”

The agressive cup feature of the Mercury Racing Bravo I and Rev 4 XC props enable them to run very high off the transom without sacrificing performance.

“We are finding the that if your currently running a standard Bravo I, and looking for extra grip, you will need to drop 2” in pitch to run the XC version. That’s a direct result of the grip of the prop,” said Eric.

The enhanced cup enables the engine to be run at elevated transom heights – without sacrificing performance. This is particularly beneficial for flats boats running in “skinny” water.

The larger blade area enables the prop to stay hooked up for quick planing and enhanced performance throughout the engine RPM range.  The exhaust tube is designed to support planing and stability at lower speeds. The combination of the extreme cup and custom exhaust tube results in enhanced low speed planing efficiency – a bonus for scouting fish in the shallows.

In most of these applications, venting is not required to plane the boats quickly; however, should the need arise, the Rev 4 XP and XC propellers are all equipped with the Mercury® patented Performance Vent System® (PVS). PVS® enables the user to fine-tune the amount of venting, if needed.

This show is a hoot. Not only is it my first time being here – it is the first time in my long career of working shows that the event will shut down for a day due to a NFL Playoffs game.  Being from Wisconsin – I’m a die hard Packers fan. But – since I’m here – and the Texan’s playoff game is Saturday – I’m all in and will be rooting for Houston’s team. Its all good – the Packers play Sunday night. I hope both teams win. 🙂 The Rev 4 XC and XP are winners when applied to the select applications in which they were designed.

  1. I would be curious to try one on a i/o setup with a very shallow drive height. Say 3″ below boat bottom to prop shaft. May prove interesting on a 20 v bottom.

    1. Sean,
      That’s the interesting thing about propellers. We design them for a particular market but hey – you never know where they may end up.

  2. Hi Scott
    I have a 2013 Lund 2075 pro v with 300 pro 4 stroke. I currently alternate between a 21″ bravo 1 fs (58.9 mph @ 6360 rpm 1 person 60% fuel, 0 – 30 mph 7.93 sec) and a 22 bravo 1 fs (60 mph @ 5990 rpm 0 – 30 mph 9.03 sec 1 person 60% fuel). Motor is 1 notch above stock, elevation here is 2100 ft ambient temp 25C. I pick up 1 1/2 mph with a bit of wind a light chop. Any role for the rev prop with my setup?

    Thanks

    1. James,
      I have not had the chance to compare the new Rev 4 XP to the Bravo I FS. All my testing has been done with twin, triple and quad center consoles. But as soon as the ice thaws, I’ll be out there testing and will write a blog about the differences between the two styles of props.

      1. Have you gotten to try the two props against each other yet Scott? I am curious to the comparison between the two as far as pitch per RPM and mph. I have my boat dialed in with a Bravo and want a second prop.

  3. Scott

    It was nice to meet you at the boat show and to discuss the benefits of the Bravo XS. The prop came in this week at Bowden and looking forward to see how the Ranger 520C does.

    Again, Thanks for taking the time to visit.

    1. Jason,
      The prop designs are different but the concept with the added cup is the same. Both offer enhanced durability and on plane performance at slower speeds for shallow water running. The Bravo I XC works so well – we decided to give the Revolution 4 15” and 17” pitch the same added cup treatment. The Bravo I XC might lower rpm too much. The low pitch Rev 4 XC will get it back.

    I just recently bought a 2016 Nitro Z20 with a 2015 Mercury 225 Pro XS Optimax with torque master. It has a 3 bladed 24 pitch Fury prop on it from the factory. WOT I’m at 5800RPMs at 68 mph. I went on the Mercury Marine website and typed in all my information I have given you for best top end speed, acceleration, mid range/fuel economy and gives me a different selection of props each time. The one prop that came up in every single example was the Trophy Plus Stainless Steel 4 bladed prop with a diameter of 13.75″ and 24″ pitch. In every example the top speed is exact same 75.32mph but the rpms vary from 5625 also the way up to 6000. Is this the prop for me?

    I’m kinda confused bc it will give you a choice of 3 to 5 different props each time but yet there is only one set of results at the bottom and that’s where the rpms vary.

    I want to buy a prop that is going to give me the best acceleration and top end speed.
    Please help me out. Call me if you would like anytime at 337-329-2184 or email me at

    Thanks
    Chris Walker.

    1. Chris,
      Typically, the Fury 3 blade you’re running should give you the best top speed with a good hole shot. Reviewing your WOT rpm and speed, hitting 68 mph is pretty good. Weight and the weight distribution in your boat does affect speed when running a 3 blade. A 4 blade often increases performance under the heavy load. Pass on the Trophy. If you are interested in a 4 blade, consider the 26” pitch Bravo I XS. The 26” should offer the same rpm as the 24” Fury – especially after the engine you raise the engine height .5 to .75” inches. The Fury id designed to run deep in the water whereas the Bravo I XS comes to life when running at elevated heights. With the Bravo I XS, XS I’m calculating you’ll gain 1.5 mph and also realize enhanced planing performance. The only way to truly know is to try it out.

  5. Scott, is there any difference between the Rev4 and the Rev4 XP, currently running 19″ Rev4 on 350 Verados(2016) 32′ Seavee non step hull. 61 MPH @ 6400 RPM. Motor is all the way up. Next question is would i gain any top end with Bravo FS ?

    1. Michael,
      Yes there is a difference. The 19″ pitch Rev 4 XP increases 100 rpm over the standard Rev 4. I would look at a 21″ pitch Rev 4 XP. Engine speed should come in around 6200 rpm and top speed should increase to 63.5 to possibly 64 mph. The Bravo I FS is a fantastic prop for the Sea Vee’s. I’m thinking that the 22″ pitch is the way to go. I suggest you contact Sea Vee directly to get their input regarding the two prop styles for your boat.

  6. Scott, I have a brand new custom built Onslow Bay 27 center console with twin 350 Verados. We tried the Bravo 1 FS in 23 pitch at first but the boat had a bounce above 58 mph. The boat builder did not like that so he went back to what he had used on two other applications. Rev 4 in 23 pitch. The boat handles excellent with the rev 4’s but they only reach 5700 rpm at 65.5 mph with an offshore load. Light the boat turned 6000 at 70 mph. he has tried the 21 rev 4’s on a boat exactly like mine and said they would over rev. He suggested a labed prop. I am thinking the Rev 4 XP in 22 pitch, what is your thoughts?

    1. Jeff,
      Glad you had the chance to run the Bravo I FS. There are two 4-blade props of choice for center consoles; the Rev 4 or the Bravo I FS. it’s always one or the other. I like your idea of the 22” pitch Rev 4 XP. typically, the engines pick up 200 rpm and – with your heavy loads – it will bring your motors into the appropriate rpm range.

  7. Happy Thanksgiving! I just ordered a 621 VS Ranger. 350 VRod, I have 19,20,and 21 pitch Rev 4’s. Is the Bravo LT another option for this boat?

    1. Brad,
      Absolutely! For a benchmark, let us know what pitch works the best along with your performance numbers (WOT engine rpm and speed). For sure you can move up 1.5” of pitch – moving from the Rev 4 to the LT. I need your numbers to see if you can move up .5” pitch higher.
      Scott

  8. Hi Scott, I saw that you stated the 350 comes with a 22 fs Bravo. The 621 will a 6″ jack plate and a. 9.9 kicker and 5 batteries with a heavier Ulterra for my front trolling motor. I will also have smooth move seat bases. I expect COG to be a fair amount weighted forward versus the 2012 621 VS I had. I will get some numbers for you in mid March, lots of ice here in South Dakota

  9. Hey Scott,
    I have a 250 Pro XS with Torque Master II gear case. I’m going to install on SeaArc BXT 220 with 7 degree prop tunnel hull with 5.5 inches at transom and hydraulic jack plate. Boat dry weight 1550 but will load heavy with batteries, power poles and gear.
    I plan to run on skinny water on the Snake River in Idaho and lakes.
    Prop calculator suggests Trophy Plus 4 blade 13.75/21 , Vensura 4 Blade 14/21. Will a Bravo 1 XC 20″ perform or any suggestions.

    1. Bill,
      There are two props that you can look at; The Bravo I LT and Bravo I XC. The difference between the two is the trailing edge cup height with the the XC being much greater. The XC was developed for the skinny waters of Texas. The engine rpm from the 21” pitch LT would equal the 19” pitch XC. Both props have a long exhaust tube which offers faster planing, ideal for the skinny water. For either prop take out the vent plugs. You’ll need to run with all the vent holes open.

  10. Hi Scott,
    We are running a 250 VRod XL on a Yarcraft 209tfx with a 21p Tempest. WOT 6400rpm and 58mph. Midrange is 4600 and 40mph. Hole shot is great. I tried out a first gen bravo1 22p. WOT 5950rpm and 58mph. Midrange is 4200 and 40mph. Hole shot is great. Love the stern lift and rough water handling of the bravo.I am very interested in the new bravo1 LT but am not sure what pitch would be best, 21,21.5,22. Thanks for your help Scott.
    Mark

    1. Mark,
      Glad you called to discuss further. The rpm spread between the Tempest and Bravo I was wide. It is the stock Bravo I used for sterndrives. There’s a big difference between the stock Bravo I and the Bravo I LT. Typically, a step up from the 21” Tempest to the 22” pitch Bravo I LT will run similar rpm. Since the engine was up at 6400 rpm, we went with the 22.5” pitch which will offer awesome hole shot and will lower the WOT rpm to 6200-6300. The biggest benefit is better mid-range cruise efficiency. Mark wasn’t too concerned about speed but my money is on him hitting over 60 mph.
      Scott
