    Picked up my first ski. 98 Pro 785

    Picked up my first ski today found a 98 pro 785. Starts up and runs guy told me it has low compression on 2 cylinders. He had 3 newer skis and a boat sitting at home and said he didn't want to throw money into it. I picked it up with a trailer and will tear into it this weekend and see what it looks like. 100% stock.

    Plans will be:

    Seat cover
    Hydro turf
    Motor work
    Intake grate/ride plate (if I can track them down)

    I am pretty excited and know this is a pretty cool ski and looking forward to getting it back on the water.

    Been trying to find any sites for parts and seems a little hard to come by.. am I just not searching hard enough? any help would be appreciated.

    Ah thought I had that written down. I am about 30 minutes west of Chicago. I plan on taking the ski to Lake Geneva in Wisconsin or up near my gf's grandpas summer house near Castle Rock Lake in Wisconsin.

    Pulled the head...Not what I wanted to see. two of the cylinders are fine but the pto cylinder was trashed...like major play etc. the head will need to be resurfaced for sure. It looks like the jug will need to be machined etc there are some scores in it.. and then be replated. I am guessing the motor will have to come out since it looks like pieces have broken off from the piston. I don't want that in the case. I would hope that the crank and rods are still good and might just need to get the case cleaned out etc.. I am new to this so I am playing the guessing game until I can figure out where to source parts and a machine shop for the work.

    Welcome to the Hulk. I'm sure Bob (785 Lugs) will chime in. He is all things Pro 785, be it parts AND knowledge.

    There are others too.

    I have a Hot Seat rideplate for the 785. Hot Seat seams to be one of the more favored plates. If you're interested, shoot me a PM.

    Also, post pictures. We love pics and it can help us help you diagnose issues sometimes.

    Bob is local and I have met him before through a buddy who has a sltx and I plan on getting into contact with him for parts.

    You will be in good hands with Bob. If he doesnt have parts he knows where to get them.

    Shit. I think I see needle bearing marks in the piston top. Sigh.
