    Gp1200R Cavitation issue, wear ring, tolorances on wobbly drive shaft?


    I recently noticed that when starting from scratch in water, its revving but not too much is happening. Took the pump apart and saw that the nylon wear ring had several uneven grooves in it.
    Now i looked at the drive shaft and it was a bit wobbely, like 1-1.5mm off, but the bearings seem ok and not flapping around.

    What do you guys think about this?

    Regards from Sweden.

    Get that plastic ring off and replace it with the proper wear ring. Those are junk.
