94 GTS First Start After 8 Years Sitting, Questions

[dogggis]

My co-worker is selling his 94 Seadoo GTS?, 3 seater. It hasn't been used since 2002 because he was injured and no longer rides (He's 60 now). He is the original owner and it has always been covered and garaged. I am considering buying it but I would like to know what things I can expect to repair and replace. Cosmetically it looks great and he's willing to sell it to me with the trailer for $1000.

Next week we're going to clean out the gas tank, fuel lines, carburetor, change oil, and new battery to see if we can get it to turn over and see how it runs. What other things should we do before starting it up? Will this be a money pit or is there some life left in it? What other signs should I look for when working on it? Thanks!

A lot of what might be wrong all depends on in what condition the machine was in prior to sitting for so long. If it was winterized and the engine was sufficiently fogged, then you will be in much better shape than if he just got done riding, machine was wet, not lubed/fogged and then it sat.

See if he can remember what maintenance he did on the machine just prior to it sitting.

You are going to have to replace the fuel lines, not just clean them (however you meant to do that). I am guessing they are the gray tempo fuel lines, which corrode on the inside and clog the fuel system up. If they are gray, you must replace them all except the vent lines. Also, clean the entire fuel circuit including the fuel selector switch.

I would also spray lube in the cylinders just to make sure they are protected prior to you trying to turn it over. Remove the plugs and spray bombardier lube in each cylinder, for around 10 seconds each cylinder. You can try turning it over by hand instead of with the starter if you want at this point just to see if it may be seized from rust inside the engine.

Inspect the oil lines, especially the two 1/8" lines running from the oil pump to the carbs. Obviously take note of any oil/gas lying in the hull. If there is some down here, you better look for a leak. If you are concerned at all with the oil injection system, you can premix the fuel you put in your gas tank.

Other than what you already stated, this is about all you should have to do before trying to get it to fire up. Somebody else will chime in if I am forgetting something. When/If you get it running, you may have other issues to deal with. Post your results and we'll see if we can help you there.

Good Luck!

Rebuild the carbs(with a rebuild kit) and replace the needles and seats, replace the small oil lines on the oil pump...
