    1997 Polaris SLTX 1050 (Help!)

    I just aquired this PWC from a buddy that explained to me that something really bad happend to it. I took it home and removed the seat to find that someone else had already messed with it.

    The three heads were already removed and all three pistons were exposed. The center top of the center piston is severely damaged.

    (I am not a mechanic but do have some knowledge)
    I began removing the surrounding parts in order to get to the shaft. Finally, I was able to remove the whole cylinder casing to the center piston and found that the arm was broken off from the shaft and lodged. There was metal shavings and debris from the arm. The cylinder has some deep scratches as it can be felt be swiping your finger.

    What could have caused this and what do I need to do now? This PWC was actually given to me and I would like to know if it will be worth fixing or I will have to dump too much money into it? Thanks in advance for your help/comments!

    Welcome

    Click below for the service manuals.

    Some pictures might be helpful, but it sounds like a connecting rod bearing failed, and the piston rammed into the cylinder head.

    The SLTX 1050 is a fairly high performance PWC. When running well, it pulls hard and runs close to 60mph.

    At a minimum you will need the crank rebuilt (requires a crank rebuilding shop), with new bearings/seals and at least one connecting rod. Plus new pistons+rings, perhaps one cylinder head and cylinder.

    Is everything else still in there? Electrical, CDI, jet pump, etc?

    Besides the issue I encountered today with the piston/arm, everything else is complete and nothing has been taken out of the PWC. Do you think it is worth fixing and putting some money into it?

    Thanks!

    Depends on your budget.

    Being a Polaris PWC enthusiasts forum, many on here would say yes, it is worth rebuilding.

    I would say it is worth tearing it down enough that you can more accurately determine what will be needed to fix it.

    Pull the jet pump, pull the engine.

    Check the jet pump for smooth running bearings with zero play or grinding feel, and proper impeller blade clearance.

    Pull the engine apart, and see what is salvageable.

    Plan to rebuild the carbs, and have a look here

    Not very good pics, but this is where I am at.
