    New to Ski's have Engine Problems

    So I picked up two 1995 Polaris SLT 750's on a double trailer today, the price was good enough that I just bought them, One of them runs good no issues so far.

    The other one was basically free with the deal so we took it, they had it out at the lake on Memorial day weekend and everything was fine they got it home and he told me that he went to flush it out at home and it wouldent start when he tried. when you hit the stater button its just a loud clunk and nothing happens, So I got it home today and started to do a little triage on it and figure out if it was repairable. So I took out all the Spark plugs and they looked okay, then grabbed a light and took a look in each cylinder and noticed that something was definetly not right in the cylinder closest to the driveshaft.

    So I took off the cooling and popped the head off that cylinder and its alot worse than I was expecting, but I am hoping that I can fix it.







    What is my next move? can I redo just the top end or is this a complete rebuild?

    Best Price for Parts?

    Welcome.

    First thing, the running machine should get some attention. There are a bunch of things to do and check to prevent it from also failing. See my signature links for more info.

    Looks like a LOT of metal debris has gotten into the crank case. You would need to pull the crank case apart to clean it out and check the crank shaft bearings for smooth operation.

    Once you have fully diagnosed what is salvageable you can decide what you want to do.

    I am going to do all of the necessary stuff to the running one over the next couple of weeks.

    for the one with the bad cylinder does the entire engine need to come out to pull it apart and get to the bottom end?

    is there any diagrams on doing this work, I've rebuilt a few motors but this is my first dealing with a jet-ski.

    Engine needs to come out. Jet pump and drive shaft come out first.
