    FX160HO Cavitation?

    Stock 2005 FX160HO. 145 hrs Open throttle wide from low speeds and the revs hit the Limiter and goes nowhere fast! There appers to be no damage to the impeller.

    There is quite a large gap between the impeller and the housing (about 2mm)
    is this to Big. I thought it would be a tighter tolarance?

    What doe you guys recomend to fix the problem?

    A new impeller and stuffer kit? which impeller do i buy?

    2mm is way to much
    if it's still the original impellor get a stock replacement
    if you plan on moding the ski with the rpm kit from riva in the future
    get a solas

    Yep as kev says 2mm is way too much.......spec is 0.35-0.45mm (0.0138''-0.0177'').....time for a new impeller.

    you need to find out why the gap is so large! Pull the pump and see if the wearing blistered out. If so you will need a new wear ring and impeller. Just an impeller will not be the fix. Did you pull the pump yet to look at the impeller or did you just look down the nozzel. If you look just down the nozzel everything will look ok, you need to look at the outside diameter of the blades and look for wear

    Good point scittb..........the stainless liner can react with the housing if water gets inbetween (especially salt) & cause a high point causing the impeller to wear.

    Skat Trak 18-24 fitted with RnD ride plate and Scope loader. Void seal kit fitted. Impeller to ring much tighter. Old impeller had two dings and a turned edge.

    Expecting big improvement on the next ride out.
