    1998 Kawasaki 1100 stx leaking hull

    Hello all, I have a 98 1100 stx that is leaking from the driveshaft through hull fitting, which I guess is fairly common. I have seen threads on how the repair is made and I have already removed the motor and driveshaft, and cleaned up the area for repair. I'm just not sure what type of epoxy/adhesive to use. If I were to use 5200, I'll never get it off again. Any input is greatly appreciated.

    I had the same. You'll never need to get that fitting off again as long as you do it properly and it's watertight after.
    Now you've got everything out, but new bearings and seals into the driveshaft bearing housing. Check that the rubber in the bearing housing is not torn too.

    I also had water coming in through old thru hull fittings and the four screws from the ride plate as the bronze inserts in the hull had corroded away.

    Cheers

    Tim

    Do NOT use 5200 on the bearing holder. Use 4200 quick dry and do not tighten the bolts all the way until after the adhesive sets up (snug it, but don't get it real tight). Somebody makes a bearing holder that doesn't need adhesive. Rhaas makes one with a polyurethane block instead of the Kawasaki-style rubber.

    Another spot you need to be looking at is under the electrical box where the shaft enters the hull. There is a cap (for lack of better words) that is sealed to the hull that creates a shaft tunnel, and that sealer commonly fails on these older ski's.

    Not the cleanest job but no water leaking here. Is that the part you are talking about?
    I put mine back in with 3M 5200.Click image for larger version.

    I have a 1999 stx with this same issue. It appears to have been "fixed" previously as I found 2 different colors (layers) of sealant underneath the top black layer which i'll assume is 3M 5200. I see from your picture you cut a larger hole for better access. How did you re-mount the e-box after cutting such a large hole?

    I did this repair for the driveshaft tunnel using 5200 as well. I did not cut out the access any more though, it really wasn't too bad with the standard hole. I also went with the Rhaas bearing holder and it is really quality stuff. No sealant needed on that one but I still put a thin layer of silicon behind.
