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!
