    Let me guess? Supercharger slipping?

    Took the ski out today and it would not go over 53....Previously it was topping out at 68 - 70. It is 11 hours from being due for 100 hour maintenance, so I assume it is probably the blower slipping?

    Does it have the stock washers in it??
    If it does I hope they didn't break and fall into the motor..

    Could be ALOT of things, If i remember didint you buy this ski and fix it up? Swap motors? Either way, What rpm’s are you turning? Jet pump area free and clear?

    More details, More answers!

    check it over right away! don't even run it until you know if the ceramics failed or not!

    Pull the rubber boot off of the supercharger intake and with engine off stick your fingers in and see if the impeller turns freely.
    Then report back.

    Nope... I had them swapped last November when I bought it. It is due for the full rebuild though @ 100 hours.

    Going to pull it tonight or tomorrow and check it out. I'll let you know what I find.

    If you have metal washers check the slip. It might need a shim or two.
    Or being your so close to 100 hours send it to jerry for a full rebuild.

    RPM's are hitting a bit over 8K, however instead of near 70, it is hitting 53 - 55 tops. I looked at the impeller and did not see any dings or nicks, and the wear ring looks ok to the naked eye. The only thing I did when I bought it was to get them to swap the washers to the metal ones, otherwise it was stock. I still have about 2 1/2 weeks of warranty left on it, so if it is anything major it should be covered. (I hope)

    If it was the supercharger the rpms should be down also.

    Pull the pump and get a good look at the impeller/wear ring.
