    Same thing happened to me on my slx. I snapped 1 of the long bolts too.. you have to undo the nuts on the inside of that housing inside the ski and pry it out of there from outside the ski.. be careful not to hit the big o-rig that surrounds it. you can reuse that on the new one. I had to remove the plate to pry the housing off. (edit,,,prying means gentle prying not to chip the gelcoat,,,although my gelcoat came off with the sealant on other holes that weren't pryed on by a knife or flat edge). might get lucky if its not on too hard with silicon. may want to try tapping on the bolt heads from inside once the nuts are loose.. leave the nuts on near the top of the bolt so you have something to hit against instead of hitting the threads of the bolts. it might come loose.

    Chase the new housing bolt holes with grease and go in just a lil at a time until the bolts go all the way down and back out again. when finished, coat the threads with anti-seize when installing them. Once everything is in again, seal the edges of the rideplate with silicon again to smooth everything over. spray starting fluid into the holes to remove any debris everytime you chase the long bolts in. it works. it will be smooth going,just grease it each time.

    I used GOOP to seal my rideplate. works great. Hasn't budged since installed. rode it hard all summer.

    The book says 18ft-lbs on the long bolts

    If your plate is sealed underneath, I used a long rounded edge , non serrated edge,slicing knife and pounded it all the way a little at a time under the plate and used a razor on the outside. it finally came off. had to clean the remains off the plate and ski before assembly.

    They should be. You don't want any air getting into the pump.

    You should realign the engine after removing the housing always.

    i thought this was the case. would the thick O-seal not help realign on the housing upon bolting up? or does it squish up funny? ive cleaned the bond sealer off, and if i offer the housing and seal up to the shoe, i cant seem to get it to move about hardly at all. it seems to want to go into 1 position only.

    still got the task of removing the two snapped bolt ends from the housing. i may weld a ss nut onto the thread end and try that first.

    You should at the very least check the alignment.

    ok thanks and will do.

    i had a odd problem with alignment once, and it just couldnt get it right. it turned out that the drive coupler or the crank end was duff, and the inner splines for the drive shaft where not concentric to the outer, where its bonded together. so it was oscilating!
