    1992 sl 650 leakin h2o

    Finally ran the old 92sl 650 after top end rebuild. It ran fine with a few minor carb adjustments. Now the only problem is it's leaking water from the driveshaft. I'd imagine the seals r original. I was wandering how hard it's going to be to fix this problem? How much trouble will it be?

    I just read thru the link and it's very informative. My 92 doesn't have 4 "long bolts". It has 4 short bolts past the steering nozzle and 4 more bolts against the hull of it. Do I take out 4 small bolts, remove nozzle, then the other 4 bolts to get the rest of it out?

    The 4 long bolts are on the larger pump or extended pump the 92 650 has a 146 mm pump you undo the nuts at the hull the bolts should stay in the hull make sure you take of the steering cable and the hoses from in side there is a o ring on the housing be carful and slowly pry the housing from the hull this was in the link I think ?

    Ok, this seems like a pretty straight procedure. Can't wait to tear into it!

    I have the pump out of ski already. The shaft don't look bad at all, but it's missing the rubber bumper on motor side and has minor grooving where the seals are. The grooves don't worry me as much as the missing bumper. Any thoughts on that? Is there supposed to be any bearings where the seals are? None on this set up.

    Make sure the rubber bumper didn't stay in the motor coupler. Sometimes they stick in there.... They are still available new or can be replaced using a similar sized o ring or cut out of rubber stopper type stock.....

    The through-hull carrier has bushings inside. If they are worn then the entire carrier can be replaced.

    Some versions of the carrier can be rebuilt.

    See the jet pump section from my signature links for details.
