  • Mako 252 Performance

    i own a 1998 Mako 252 with a single Honda 225 four stroke. The boat is underpowered and top speed is 34.5mph. Can anyone provide performance info if i switch to twin 150 four strokes?

    I would try others wheels, those numbers should be higher. I would expect at least 38-40 mph top end at the worst case.

      Hammertime has a 254 with a single Evinrude 225, his numbers a re better than that, perhaps he'll jump in. []

        WOT for that motor is about 6000rpm... What are you turning with your currnet prop? If it were mine, I'd go twins. Thats alot of boat for one motor.

          I agree with Ed, that's a lot of boat and a world of difference between the "new" 252 and the "old" 254/251.

          You need to be thinking 250hp as a MINIMUM -- twin 150s even better. A single 300 HPDI would be an interesting choice in my book.

            hmmm.... a single 225 would be just about right for my 23'er though.

              The top RPM with current prop is 5500. I've tried other props gaining higher top end rpm, but speed drops off a little. It's just too small for this hull. If anyone is runnig twin 150's on this hull, i would love to hear from you.

                I have a 78 Model 25 that we repowered in March of 2003 with twin 140 HP Johnsons...these are actually Susuki motors painted white. I could not be happier with the results. Trolling (1600 - 2000 RPM)we burn less than one gallon per hour combined total. We normally cruise at 20 - 22 knots and average 1.4 to 1.6 gal per nm total.

                3800 RPM = 18 knots 4000 RPM = 20 knots 4200 RPM = 22 knots

                WOT = 6000 RPM @ 35 knots

                All data is with full fuel...140 gallons, fish box full of ice and bait...150#s, and 4 to 5 people.
