You came to the right place!!!!
Hi all, I am brand new to this forum and I am learning my way around. Just got a seadoo off Craigs list....FREE! Of course I know nothing about it other than the carbs are off and apart. I am looking in threads on putting them back togather, however as I know nothing about these, I will probably ask 10,000 questions. I dont know model or engine so when going thru threads, I seem to get lost. Any welcoming info would be great. I like to use the search button and see where folks had similar issues, but not knowing anything about this thing has me looking for simple starting points.
Thanks,
Well, welcome to the forum. I should say, you came to the right place for info. Surprised to see that you can still find one of the original skis. The Seadoo actually first came out in 1988 but sold in 89. Your model ski is the SP. It was the first model of many in the later years to follow.
If your ski is all original, the engine should be yellow. This ski uses the yellow 587cc engine with the single Mikuni carb set up. You'll probably run into a time finding parts for it, since most parts for this ski have been discontinued. That doesn't mean you won't find some parts, because you will. You will still be able to find carb rebuild kits and even a newly remanufactured motor, if you need one.
The first thing I'd do is a compression test. If you basically got it for free, before you dump any money in it, you need to know what shape the piston and rings are in. You can buy a compression gage at any auto parts store for about $25 bucks. You will use it more than once, so if you don't have it, get it. Though compression on a new motor is between 140 and 150 psi, it's most important that the pressure spread between the two is 5 psi or less.
If you have good compression, the next thing your going to want to check is spark. Take a spark plug and attach it to the wire. Lay it down across the head of the engine (on a shady, overcast day or inside the garage to see the spark) and push the start button. If your coil and ignition module are good, you'll have spark on the plug. If not, then you'll need to trouble shoot this right off. Replacing the module may cost you more than the ski is worth.
So, take steps in that order and let us know what you get. This info is enough to get you started.
