Thread: slow to plane

  1. #1

    Question slow to plane

    I just bought a 1995 900 ZXI and got a few bugs worked out. Today I put it in the water for the first time. It acts like something is slipping, it will barely get out of the water. Once it planes off everything seems ok.

    Forgive me but I am new to jet ski's. Maybe something around the impeller? Where should I start checking?

    Thanks

    quick checks

    something wrapped around the driveshaft
    or
    something stuck in the jetpum
    or
    damaged impeller
    or
    damaged wear ring

    I went and looked at the impeller and it has some minor nicks. The engine will rev real high and it just seems like something is slipping.

    Get a new prop.

    Your cavitating "spinning the prop". Common on old worn out props. May look good but be out of pitch.

    Could also be improper sealing of the pump and/or intake grate. Check the clearance between the impeller blades and the housing (I don't remember what it should be on your 'Ski, probably less than .020").

    Pump Rebuild time. Bearings, seals, impeller
