Welcome back!!! It is great to see another Polaris is getting rebuilt instead of becoming landfill. I am also rebuilding a 1994 SL650, check out the links in my signature. It is getting a few 'slightly modified' parts and other 'subtle' upgrades while I am at it. Post lots of pics. We like to see your progress as you go. If you decide to restore it as stock, let me know, I may have a few extra 650 parts...cylinders, pistons, brand new rings, heads, etc...

Oh yea reed valves would be nice as i think i blew them out.
I was trying to get the old beast running and i put some gas down the carbs it fired then back fired and shot flames and smoke out the center carb opening causing a wild chain reraction lighting my gas can on fire that was conviently placed on the side close enough to ignite and 1 fire extinguisher and 3.50 wasted in gas it was over with i put the seat on and called it a day

How much would a full engine rebuild cost just gaskets and minor stuff

At least you were smart enough to have a fire extinguisher handy! I would say you should check out those reeds before you try to start it again. Flames in the hull can cause serious injury. Fuel vapors are very explosive! Thank goodness you didn't get burned or worse.

A rebuild kit runs about $270 and contains all the gaskets needed.
But, you'll need to have the cyls bored for the larger pistons, and to remove any imperfections in the cyl walls. Anywhere from $40 - $60 a cyl, depending on who does them for you. Plus the cost of shipping both ways if you send them out.
You'll most likely want to rebuild the carbs while you're at it. Ignoring them may cause a lean condition and damage your new pistons. There's a good carb rebuild kit on Ebay for $130 that does all 3 carbs.
If you haven't addressed the fuel pump, I'd look into that too. That runs around $26.
And finally, I'd replace all the fuel hoses. That should run around $30 to do the entire ski.
It's not going to be cheap by any means.
I'm sure someone will help you out with reeds and small parts like that, but you definately are looking at quite a bit of $$$ to sink into that ski.
Another option may be to buy another engine (650/750 or a 780 with a new exhaust manifold) and sell the parts from your engine to help cover some of the cost.
This may be a cheaper route, and gain you some more HP in the process.

ok ive adressed the pump and lines im going to take photos of cylinders i really dont wanna get the pisons and such bored and ive done all the stuff that causes lean condition except the carb rebuild and im going to take the motor out to do all this so yea.
Now theres a story to this jetski and why i got it for free...
I was driving my golf cart around the lake taking my usual looks and noticed something i havent seen before it was the jetski, i bieng myself talked to the man and we talked for about 5 minutes before i brought up the ski he told me a sad story about how his son had taken the ski out flipped it and sucked A BUNCH of water into it ( i think he said it sank) and now for the bad part.
They took the ski out of the water dained the hull AND LEFT IT!!! THEY DID NOT DRAIN THE MOTOR!!! It sat for a year with water in it thankfully it didnt freeze and the man took it to a mechanic he drained the crancase but came back with bad news the main bearings had begun to rust so the man took it drove it for awhile and left it in his garage for 3 years then I came along towed it home tinkered and got sputters now im to this point...
