    07 ultra 250 upgraded pump-bearings

    Just bought the ski. Took pump off to check bearings. How do you know if it already has upgraded bearings. The prop spins by hand nice. No noise and no play. Also it has a 16-21 solas prop. Is that a factory prop. Thanks for the

    If I remember rightly the shaft should be knocked out the back, and then you need a drift to knock the front bearing (s) out the front.
    The 2011 set up has a rear jam nut which you should see without taking it apart, like said on here upgrade to that. Even if you have the 2 front bearings, you may as well replace it now it's apart and base line the pump, so you know 100% the bearings were replaced at XXX hours.

    16/21 solas is aftermarket. I have it. Works well over the factory prop
