A smaller lighter boat and the correct prop

well im talking about just the motor in general, like on all these 2-stroke motors out there, everyone puts a tuner and carbs and reeds and exhaust and all that good stuff on it and what not to help with speed. can you not do that to a 4-stroke? or do they not make parts like that for these small 4-stroke motors?

Larger prop is needed, but you need more HP to turn it.
You would be better off buying a bigger motor if this 25 is not what you want.

Might find a racing forum and ask there, they might tell you to put a nitrous kit on it, carbs,cams, different ecu, exhaust, etc.

Most modified motors are not as reliable as the factory designed motor, ever notice how often race motors are taken apart and redone
