    Its 97 model a little rough I kinda think it was used to race,because in tennesssee ur supose to register them and put the registration number on the hull and this one dont have it.It deffinatelly needs a good cleaning,,the top end was already tore down when I got it.I bought a double trailor and the guy included it with the deal for $600.00 so I figured I cant go wrong.

    Hey tosborn, I have a pro 785 too (though it's a 9. You should be proud because there will never be a PWC like a pro 785 again.

    For parts you should go to

    Polaris stopped making PWCs a while ago so parts are getting hard to find at times. They're even worse for the pros because they were made in limited quantities.

    The cylinders are nickel cadium plated, so you shouldn't bore them out. You can order new sleeves from la sleeve. As for new pistons, don't both looking for stock ones. Grab yourself somes Wisecos pistons.

    Make sure to keep your exhaust ports clean. The difference between clean and dirty exhaust ports is huge!

    And some gaskets are really hard to find. LA Sleeve still caries gaskets, pistons, wrist pin clips, etc and the price is good. since you're rebuilding I'd suggest grabbing a cometic gasket kit, new pistons, and everything that goes with the pistons (wrist pins, etc).

    Do not feel like you have to get the parts through Polaris. I recently cleaned out my exhaust port valves and partland wanted 20 dollars per exhaust port gasket. I called a supplier and got a 2x4 foot sheet of exhaust gasket material for 20 dollars and made the gaskets myself.

    Look around when looking for parts, there is no single good place to get parts for a pro anymore without getting raped.

    But enjoy your ski, the pro 785 is fucking sick.
