1991 Seadoo XP - What to do with it?

[Adriver]

Hello,
I have a 1991 Seadoo XP that has not been used in at least 10 years. It has very few hours on it. It probably wasn't on the lake over 12 times since we purchased it new. The last time we took it out we couldn't get it to start and I am sure it was from carb problems from not being winterized. I am trying to decide what to do with it. My wife doesn't want to sell it, but I have never worked on anything similar before. Is it worth the trouble to try and rebuild it? If not would it be better to sell it outright or part it out? We do not have the funds to have it fixed professionally. Any advice would be appreciated.

Thanks,
Adriver

If its in good condition I would at least replace the grey lines, change spark plugs, clean out gas tank/replace gas, clean fuel selector, go through the carbs (good cleaning) and change the jet pump oil, that should at least get you up to par and then you can make a decision from there. It would cost no more than $100 to do all that yourself, just pick up a manual for your ski, pretty straight forward.

While we hate seeing seadoo go to the grave.

Its going to cost more to fix than a new to you working ski.................

You could go through the basics and see how deep you'll be.

If motor not locked up, start with a compression test. Should be close to 150 if normal.

Then move on to change fluids(gas/oil) with changing of grey fuel lines and carb cleaning
Then would be servicing pump. Remove 4 bolts.........

If all that is done and works then you'll be out ~300.

Battery 100
Fuel lines + clamps 35
Carb rebuild kit 50
Jet pump bearings and new wear ring ~100

If you need a new motor it varies b/w methods of replacement. All will exceed cost of ski!!!!!!!!!!

Hope this helps

'91's didn't have grey lines. (lucky for you!) First I would put some 2 cycle oil, or fogging oil down the cylinders and turn the engine over by hand to lube up the rings. Then a compression test to see if the engine is worth saving. (probably is if it was maintained) As said above, jet pump oil (replace the cone o-ring and blue loctite the 3 bolts) And grease the through hull fitting and PTO boot. (under the grey cover at the back of the engine). Then to address your first problem, the carbs. Your xp came with 1 or double carbs. You will find out as soon as you remove the flame arrestor. Remove the carb(s), and because they have been sitting for so long, I would clean AND replace the diaphrams (use genuine mikuni kits only). Check the pop-off pressure and make sure you are in spec. (you can build a tester for under 20$)

Also, I think its a given, you will have to drain the fuel tank completly and flush out the lines. For the cost, I would drain the oil tank too and change the inline filter. Refill with xps mineral oil or API-TC equivilant oil. Not TCW-3.

I think the first thing I will do is check to see if it is locked up as - BiRkS_ stated. If it's locked up after oiling, there is no use going forward for me. Until the big flood we had a couple of years ago, it had always been garage kept. It was serviced every year until the one year we didn't winterize. I found the manuals for the XP and the Mikuni carb. I'm pretty sure I remember it having two carbs. I think that was a big selling point they were pushing when I bought it in 90'.
