I am very excited to share with you information regarding our latest prop offering. The all new Mercury Racing Enertia ECO XP offers “Extreme Precision” when dialing in engine speed for maximized power output and efficiency on recreational bay boats and center consoles. It has been my experience that adding  pitch sizes in 1/2-inch increments is helpful for those who need an option when the available pitch range is greater than one inch from one to the next. Being able get the engine to run as close as possible to its max rpm operating range will enhance overall boat performance and fuel economy.

Our propeller techs customize blade cups to offer 16.5”, 18.5”, 20.5” and 22.5” pitch sizes to compliment the Mercury Enertia ECO line which ranges from 17” to 23” pitch in two inch increments. The ECO XP features the Mercury patented Performance Vent System® (PVS). PVS® enables the user to fine tune the amount of venting needed for quick planing. The standard length exhaust tube, in addition to reducing the time-to-plane, also provides stern lift for maximum hull performance and an improved ride in a variety of conditions.

  1. I’ve been using the Stock Enertia ECO 21 and I can spin it fine with great results. Never was able to try a stock 23 pitch version. I wanted to know if the Eco XP in a 22.5 what will it do compared to a 21? What are the RPM differences from stock to modified and what else will I see in performance from a Stock to XP version Enertia ECO?
    Thanks
    Phil

    1. Phil,
      The ECO XP was developed to maximize engine rpm for improved fuel economy. If the 21” pitch doesn’t allow the engine to operate in its recommended rpm range, switching to the ECO XP might be an option. For example, if your engine was revving to 5950 rpm (hitting 56.3 mph with the standard 21” pitch ECO), switching to the 20.5” pitch ECO XP (made from the 21” pitch ECO with some modification) increases engine rpm 100 to 150 (depending on the set up). Increasing engine speed by 100 rpm will result with a 1 mph gain in top-end speed. Increasing engine speed by 150 rpm results in a gain of 1.5 mph. The same will occur at mid-range for enhanced efficiency and fuel economy.

  2. Hello guys.. Excellent idea to produce half inch eco xp.

    The same applies to 19 compared to 18,5? The gains sou be 100rpm min to 150rpm max?

    All the other prop characteristics are the same?

    Thank you.

      1. Thank you very much for your reply.

        Could we possibly know when should we expect this prop in Europe?

        Thank you very much.

  3. Hi Scott
    Could you comment on how the Eco enertia xp would perform on a Lund 2075 pro v with a verado 300 pro fourstroke vs the bravo 1 FS.?

    Thanks

    1. James,
      Thanks for the question. We’ve tried them both on your rig. Hands down, the Bravo I FS offers the best performance. It offers quick planing with minimal (stress the minimal) bow lift where, like most 3 blade props – the ECO XP offers a great deal of bow lift during planing. Both are comparable at mid-range under slight chop. In big water, the Bravo I FS offered better boat control and a smoother ride. The Bravo I FS keeps the bow lower – enabling the boat to cut through the waves. Often with 3 blades, the bow rides high – causing the boat to bounce or slam into the waves. Top speed was interesting. The 3 blade offered a great deal of bow lift. Speed dropped 3 mph into the wind compared to with the wind. The 4 blade picks the complete boat up resulting in faster and and more consistent top speeds (with and into the wind).
      Thanks again,
      Scott

  4. Hello,

    We still do not have any news from eco xp in europe. Is this prop available in merc dealers? Is there any future plan for 18″ eco?

    Thank you.

    1. Loannis,
      The ECO XP should be available, we’ll check on our end to making sure Mercury International is aware of the product line. Not sure about the 18″ pitch but with Mercury – you can count on us always looking at opportunities.
      Scott

      1. Thank you! I am looking forward to hear news because in the local dealer they don’t even see it available in the factory. They only see the part number but not pricelist etc.

  5. So I see Mercury has released the Enertia ECO in 17,19,20,21,22,23 now. How is this going to effect the XP versions?

    1. Phil,
      The ECO XP evolved after the Enertia ECO prop line was released. For example, the 16.5″ pitch XP is made from the 17″ pitch ECO with a goal of gaining 100 to 150 rpm. The XP complements the ECO; providing an opportunity to maximize the engines rpm for improved fuel economy along with top speed.

  6. Hello i have a 28 feet rescue Rib with a single df300 suzuki with a 22 bravo prop (standard bravo)
    at wot 6000 Rpm 52 Mph if i switch too Enertia eco or eco XP
    what Size do i need too aim for for 5900-6100 Rpm
    looking for higher cruise speeds at 4000 rpm and maybe little more top end i also need good reverse thrust because the boat is on a floating dock ,how is the enertia eco reverse thrust compared to a bravo prop

    1. Menno,
      The 20.5” pitch Eco XP will offer the closest match to the stock Bravo I. What is your gear ratio? Also – what speeds are you achieving at 4000 rpm? With that information I can use the slip calculator to see how well the Bravo I is hooking up and see if the ECO props would benefit you.
      Scott

      1. 2.08:1 is the gear ratio of the df300 at 4000 rpm i go 30 – 32 mph with the Bravo 22 prop
        How is the reverse thrust of the Enertia Eco

        1. Menno,
          It appears you set up is generating 20%+ slip at 30-32 mph. The ECO is designed to reduce slip in the mid-range and the new 20” pitch ECO should generate similar rpm as the 22” Bravo I. We can make an educated guess that your prop slip would drop somewhere close to 14-16%. Calculating the estimated speeds using 20” pitch ECO, 4000 rpm, 14-16% slip, the slip calculator shows 30-32 mph.
          Scott

    1. Tim,
      The ECO is a fine prop for the right application. However, in this case the Bravo I FS preforms better. The Bravo I FS offers little bow during planing whereas the ECO produces a great deal of bow lift – resulting in a brief loss of sight during planing. At WOT, ECO bow lift continues and into the wind he boat feels like a kite. This attitude affects hull efficiency, scrubbing 2 – 3 mph compared to the Bravo I FS.

  7. Hello again guys,

    One month ago i have asked about the possibility of having an 18″ eco in production. I have recently noticed that mercury produced 18″ eco.

    Now the question is what difference should we wait for between eco 18″ and eco xp 18.5″ in rpm and in riding characteristics?

    Thanks in advance!!

    1. Giannis,
      Yes Mercury Propellers has the ECO in 1” pitch increments from 17” to 23” pitch. Mercury Racing has the one half pitches from 16.5” to 22.5”. If you’re running a single application, I would lean toward the 18” pitch. The one-half pitches are geared toward maximizing performance for center consoles.
      Scott

      1. Thanks Scott,

        I did buy the ECO 18” and performed better than 19” to my boat. Before I could reach with difficulty 6050-6100rpm. Now I can always see 6200rpm and I have even seen 6350 with less loads.

        The motor gained 150-200rpm with the boat in its average loads, 1 knot faster in wot, better fuel consumption in the whole range.

  8. Currently have a crest 24 ft triton with a suzuki 250ss 4st. Current prop is a suzuki 16×21.5 3 blade. I am looking to get a new prop and have always had good luck with merc props. Would a eco xp be a good prop to try? The lake the boat is on is restricted to 40 mph which the boat has not issue getting to. I am looking for great hole shot and mid range cruising.

    1. Doug,
      The ECO was designed specifically for what you’re looking for; good hole shot and improved fuel economy. I think it would be well worth a try. The 21″ pitch ECO would match up to your prop – offering similar rpm.
      Scott

  9. We have a 9m passenger “seafari” rib we use on tours in the Bahamas – we are currently running Verado 250, HD Gearboxes, 1.85:1, with 19″ Vensura props. We top out at 6100rpm and 45 knots. Would the Enertia Eco 19″ be a good replacement, or should we drop to 17″ or 18″? Will we see a better cruise (~4000rpm) speed/mpg?

    1. Lee,
      The ECO props run tall in pitch so plan to move down to the 17″ to achieve similar rpm as the 19″ 4 blades. If we had your speed at 4000 rpm we could place your information into the slip calculator to get an idea of what to expect with the ECO.
      Scott

  10. Got to test the crest triton with a suzuki 250ss. Gear ratio is 2.08. @4500 rpm the boat is going 38 mph on gps. Boat seams to be over proper with the suzuki 16×21.5p prop. Since my lake is restricted to 40 mph and I have no great way to test for the proper prop what would be a good spot to start on pitch with the eco prop? Rpm range is 6300 on the top for this motor. Since the lake is restricted on top speed is there any harm in moving down to a 19p eco? Would I lose any load caring ability? Thanks

    1. Doug,
      The ECO props run tall in pitch; more like a 22″ pitch prop. It will most likley drop engine rpm a little compared to your 21.5″ pitch prop. The lower pitch ECO will offer quick planing and the ability to stay on plane at slower speeds as well as carry a load better than a taller pitch prop.
      Scott

    1. Doug,
      The three blade props usually perform the best. The Enertia (not to be confused with the ECO Enertia)is an awesome pontoon prop.
      Scott

  11. I own a Canyon Bay 2475 bay boat. With a fibreglass T-top, 100 gallon fuel tank and 3 live wells, it’s fairly heavy. The boat is equipped with a 2007 Suzuki DF 300 with a 15 X 20, four-bladed Suzuki propeller. Hole shot is okay with the jack plate, top end (run twice upwind and downwind on a lake) averaged 51 MPH at 6100 RPM. I didn’t conduct a midrange check but during a previous trip I was running 40 MPH at 4600 RPM (approximate).

    I’ve been intrigued with the Enertia ECO to improve fuel efficiency and perhaps gain a mile per hour or two on the top end. I ran the numbers on your Prop Selector application on the Mercury website and it recommended 21 inches of pitch for the Enertia ECO, much to my surprise. That seems counter-intuitive from what I’ve read of the larger diameter ECO. The maximum allowable RPM for the Suzuki is 6300. Does this recommended pitch square with your experience?

    1. Joe,
      The ECO runs tall in pitch compared to the Mercury Revolution 4 propellers. Howver, compared to your propeller – I’m not certain how it compares. For example, if your 20” pitch offered similar rpm to the Mercury 20” pitch Rev 4 then look at the 19” pitch ECO to achieve similar rpm.
      Scott

  12. I have a 22″ rib with a df300 hp Suzuki with a left turn 16×18.5″ prop. It seems after planning the steer cannot turn to right without applying great hand effort. Do you thing that enertia eco 16×19 or a bravo I fs can solve my problem.??

    1. Akis,
      Running a 4-blade prop does reduce steering load. If the boat reacts better with bow lift, run the FS. If you think the boat requires added stern lift, then it’s the LT.
      Scott

  13. I think I am getting some bad information from the customer service reps at merc. I just rigged a 2009 Verado 300 on my 1989 Radcliffe Marine “Beaver 22″ with a 2′ bracket. Boat fully rigged and loaded weight about 6000#.
    I initially used the Merc prop selector and installed the Enertia Eco in 16 x 17 RH.
    Current performance numbers are WOT 5450 @ 45mph, hole shot is good. Other than the low wot I love the performance of this prop.
    To bring up my WOT I tried a Michigan Wheel Vortex XHS (992003) in 15 x 17. figuring the -1″ in diameter would give me +400 rpm at wot. What I got was way different. WOT 6500 @ 38 mph bouncing on rev limiter, blow out on hole shot.
    So today I called the Merc csr and he told me to forget all numbers from the Michigian wheel and get a 15” Enertia. I told him that I did not think I could an Enertia in a 16 X 15 and he said “diameter does not make a difference in performance ” As a professional aircraft technician for over 30 years and having propped many other boats this did not seem right to me so, I am reaching out to you for your help and recommendations.
    Unfortunately I do not have a Merc dealer near me in the prop demo program.

    1. Russell,
      Using the 17” pitch Eco as the benchmark; the Eco’s run tall in pitch compared to many Mercury propellers. The 17” is lowest pitch in the standard Eco line, Mercury Racing makes a 16.5” pitch Eco XP but even that isn’t low enough in pitch to get your engine into the appropriate rpm range. Mercury’s Consumer department did make a good selection with the 15” Enertia, it should get your engine in the engine’s rpm range of 5800 – 6400. How do we get there? The Eco 17” pitch should offer similar rpm to a 14” x 19” Enertia; moving down to the 15” Enertia should offer 600 to 800 rpm and a 16” Enertia 450 to 600 rpm increase. They only other Mercury prop to look at for your boat is the 15” pitch Mirage, designed to carry heavy boats offering good boat control in rough seas and it won’t be as fast as the Enertia. If you run on inland waters consider the Enertia and for offshore consider the Mirage Plus. There are so many different engine and boat combinations it’s hard to say exactly which prop to run and what rpm you’re going to get; but we can offer these suggestions to help you make an educated decision.
