    This going to be sound crazy but would you do that?

    Put a modern 4-tec supercharger in small 1994 seadoo xp? I am working on one, gutted everything out to doing 951cc conversion from other donor hull but my guts say why not go for that bigger engine if I ever find one 03-04ish damaged hull or no title for donor at good price. But how about the weight limit on small hull will that be possible with that 4-tec engine???

    I started one , had a 4 tec in it and pump of and RXP bolted up ...

    Besides glassing up engine mounts and fitting pump shoe and retro fitting carbon seal it didnt seem to hard ...

    The intake mani looked like a tight fit ...

    But lost interested as had other things happening ...

    mayb the slightly bigger gsx hull would make a better fit than the xp...i would live to see one of these things built i had a 96xp last year stock and it was a blast i could imagine this would be insane !!

    I dont get it ... the rxp hull is too small for any real power
    what good is more power when your not in the water

    What about a 155 NA motor? No supercharger = more space. You'd still be doubling the HP of the original ski. I have a wrecked 155 GTX with running motor. Let me know if you're interested.

    It wouldnt be the length of the motor that is the problem.... it would be the width. i.e: intake mani and exhaust mani
