    I just pulled my pump assembly off to allign the engine and when I pulled the pump cone off water went everywhere, is this normal? I am also missing the two rubber bumpers off my driveshaft does anyone know where I could pick some up at?

    There should not be water inside the pump cone.
    The bearings are steel - water makes rust.

    When you spin the impeller on the stub shaft, do the bearings sound rusty?
    Does the impeller shaft spin smoothly in the bearings?

    They dont make any sound however the ski has been sitting for a while and when I first turnd the shaft it felt like it was pulsing like the grease in the bearings was hardened but after a few turns it became smooth.

    I believe the bearings are sealed, rightl? If so, and they're making that noise I would replace them.....This would be a good time anyways to replace the old bearings, and put some fresh ones in there...

    Nothing but air should be in there. I would replace the bearings and seals. As if they sieze up, it will make for a bad day.

    Anyone got a place for buying the seals?

    I got bearings from Mcmaster Carr, but no seals. I'll buy a boat load, and people can just get them from me when they need them.

    the polaris pump cone will hold water in little pockets around the pump cavity, it doesn't necc mean that water got into the bearings. if you can see rust on the bearings, or it feels rough when you spin the prop, then replace the bearings and seal.
