    SL 650 ?

    Bought a 650 and it acts like its spinning out with me on it. I weigh around 250# Everyone tells me it shouldnt do that. With people around 110- 175 it takes right off. Anyone got a thought?

    The weight limit is 400#, you're well below that.

    It sounds like a stripped driveshaft or cavatation issue.

    Check for an obstruction in the intake area.

    Check the impeller to wear ring clearance.

    Check the driveshaft splines on the impeller end and the engine coupler.

    Another possibility is the pump shoe may need to be re-siliconed to the hull. Can you see exhaust soot inside the pump intake area?

    Let us know what you find out.

    Service limit is .020" or .5mm.

    Normal clearance is .002-.008" or .05-.20mm

    WAY TOO BIG......

    Either impeller, wear ring, or both are shot.
