    Low top speed, Impeller worn?

    So I am in the process of rebuilding my ski (new motor in, now redoing the fuel system) my question is between the two I had one was always faster, pretty noticeably. I havenít feeler gauged the wear on the impellor but would a worn impeller cause loss of top end speed?

    Excess blade clearance between impeller blades and the surrounding wear ring will reduce thrust.

    So will dinged, bent or damaged impeller or stator blades.
