    Go ahead and check your SC just to be sure. Pull off the intake and see if the impeller spins freely. Did you take on any water and have you looked at the exhaust yet?

    x2 on SC slip.

    Either that or you have a serious boost leak (poped off charge pipe) or the very unlikely scenario of something more sinister.

    What should the supercharger fill like? didnt take on no water and what should I check on the exhaust, what in the exhaust would make the power go away? I had part of the water box come loss before and clog up the outlet and it changed the sound but this sound is different, didnt lose this much power either

    Im not sure but check everything you can check on it. If your SC impeller spins easily by hand (continuous turns) then you may have dropped a washer.

    If I lost a washer that means the SC would be slipping? Wouldnt the rpm's be the same if not hitting rev limiter but the ski wouldnt be moving hardly at all, Kinda like a clutch in a car. Whan it comes to skis I really dont know that much, Im a rookie, Im good with V8's lol

    If you lose a washer the SC will stop working completely.

    is stated above remove the supercharger intake pipe, put your fingers in, if you can turn it its shot
