    grease under driveshaft tube

    i was working on my slt 780 and noticed that there was grease building up on the hull of the ski under the driveshaft tube right where the plastic cup mates to the back of the motor in front of the zirk fitting for greasing the drive..im guessing this means either the housing is cracked or the grease seal is leaking?

    Sounds like it. Or the previous owner was really over-greasing the fitting.

    Those seals are inexpensive and not that hard to change, once you have the jet pump and drive shaft out.

    yeah do you have any posts about jet pump removal and how to remove the driveshaft? and does the driveshaft just spline into the engine output like a normal driveshaft or does it use some kind of locking c clip?
