    96 700 slt water problem

    Finally put the slt in the water today,runs great but water is leaking out at drive shaft boot. will all the seals have to be replaced? Got to much money in it to stop now!Never buy a ski that is not running!I have not run it long enough or even enough out of water to hurt the seals

    The through-hull drive shaft bearing seals are not expensive, and are not hard to replace.

    Jet Pump Maintenance and Service

    Water is leaking into the hull around the drive shaft
    Check that the water is not coming from the small hose nipple on the speedometer pitot, which is directly below the drive shaft.
    Best way to check for leaks is to strap the hull to the trailer front and back, back it down the launch ramp until the jet pump intake is submerged, and run the engine with the hull strapped down.
    You can leave the seat off, and find out where the water is coming from.


    Replacing the seals and bushing in the through-hull assembly


    There are different versions of the through-hull bearing
    Early units with crimped ends can not be repaired, but they can be directly replaced with the newer style assembly (1996-2004, except MSX)
    Well, maybe the crimped style can be rebuilt
    Click here for a list of parts sources

    The seals tend to wear more than the brass bushing, so probably do not need to change the bushing, unless it is worn.
    Replacement seals can be purchased from any Polaris OEM parts source, or generic seals may be installed.

    Will I have to take the pump apart? can I just remove the 4 long bolts and slide it out or do I have to remove the whole pump? You sure have been a life saver for me Thanks

    Removing the jet pump is not hard to do.

    How to remove and re-install the Polaris 148mm jet pump

    Once you have the drive shaft out, you can remove the through-hull bearing assembly. Then replace the seals, and put it all back together.

    Arrow Through-hull uses Teflon impregnated self-lubricating bearing, not brass bushing
