    Prop pitch

    Hello all, been gone for a few years due to my Wife's ongoing illness. Last info I read about the 250X prop was the stocker was still the best for top speed, so I wondered if that has changed? Is there an aftermarket prop thats better than the stocker for top speed?

    I tried searching this but found nothing. I ride smooth river water and want top speed gains. Last year my best gps speed was 69.9, hoping to get to 71+ with some mods this season, want to have a spare prop so was looking for a faster prop to install and keep the stocker for a spare.

    Thanks guys

    OK, thanks. I think I will send the whole pump to Dave at Impros and see what he can do with it. His site shows several different mod for top speed, and now i'm reading about the bearing failures. Thats a new one to me since last time I was here.

    the pump is the first mod you need to do before you put your ski back into water, next open up your air vent in front that will give more air to the engine

    that new prop can pull over 2mph. but if you dont beef up your engine components then you will blow up the motor.
    not talking about bolt on mods.
    the picth is so high that at high revs the crank isnt designed to be under that much load.
    stay away from it.
    unless you have beefed your engine.

    Pulled the pump out last night, the blade to liner clearance is .019" to .021" with some signs of cavatation burn on the edges of the blades. It does cavitate out of the hole now at full throttle since I did the timing mod so I will have Dave build up those blades for less clearance.
