Im in the camp that thinks "if it wasnt built for skiing, then I dont really care how fast it goes". Fast ski boats are pretty cool.

Done properly, a "fast" ski boat is more than just a thrill- it enhances skiing performance as well. Lighter parts = smaller wake, more power = better holeshot, better speed holding, more throttle response, higher top end... so better for barefooting, pulling larger ski acts, etc.


Nothing to argue with there.

I just upgraded my prop to a 3 blade 11.5 pitch 13'' and noticed a big difference in the boats performance.

Engine Control Module, its the brain that controls the engine and fuel injection.

Is there a benefit in changing the ECM out to a higher performance one?

Only if you change out engine components such as cylinders heads, rocker arms, intake manifolds, throttle bodies, camshafts etc.

I ask again, what are your performance goals? What is your current top end mph speed and at what engine rpm?

plus you will need a new transmission if you pass the specs on your current trans.

There is no magic pixie dust. Your motor will perform as designed unless there is something impeding performance. If you want to increase performance, then you have to do engine mods: heads, cam, cylinders, etc. If you want to maximize performance of your current setup then clean the fuel delivery (carb, EFI), make sure plugs/wires are good, timing/ECM are right, all the little things can add up performance-wise. Also, find a convenient place to buy non-ethanol fuel !
