    Strap the ski onto trailer, back it in the water till it's submerged about same level as you were riding it. Take off drive shaft cover and check for leak with engine running.
    It's very likely that you have worn out drive shaft seals.

    Depends on how "hard" you ride it too. I'll get water in both of mine, but most of it gets sucked back out via the siphon tubes. The pinhole in the 90 should be there. Make sure it is cleaned out. Blow compressed air through the rest of the line all the way through the jet pump as well.

    The pin hole is a anti siphon feature. It allows the pump to suck water out, but it would break a natural siphon so water does not come back into the hull.

    also make sure it is not coming in at your speedo pick up.

    we have new Drive bearing / seal carrier's here, if you need;

    ours has REAL needle bearings, instead of just a bushing (the OEM Polaris part uses bushings).

    Nice price for that John.

    One quick Q though, how does the engine coupler cover attach with that?


    Lippy, do as they suggested and back the ski in the water on the trailer and run it with the coupler cover off. There was an update about the thru hull fittings needing re-inforced. Yours may have a crack in it allowing water in. And yes, that pin hole in the siphon fitting is supposed to be there.

    Also check the 3/4" water inlet hose going to the exhaust pipe, they have a sharp bend & often crack where attached, its hard to see.

    HI Kev.

    i need to get some pics. when we do them here in the shop, i modify the OE cover, to fit. i drill a 1/2 inch hole to clear the grease zerk, then cut some material off the bottom side, and clamp the cover right on the metal housing. you MUST remove to grease, but it really only takes a few seconds to do.
