Stay away from Sea doo's in general. A lot of problems and very expensive parts. back when I used to be into the jet ski thing, every time i put them in there was always a sea doo ont he dock with problems.
Ask about the CDI box, has it been replaced, if not, its going to be big money
How many hours? that model, if i remeber correctly does have an hour meter, anything at 150-200 is getting close to a rebuild.
Dont ever buy a jet ski/wave runner/sea doo etc... unless you have done a compression test, if you dont have the gauges, then buy a set, this will save you money in the long run
You must water test the ski, if u cant water test it, dont buy it
Make sure it has ownership, lots of skis out there do not have ownership.
Personally, i liked Kawi and Yamaha for jet skiis, not sure what you want it for but if its mostly for solo stuff, look at the stand up models, way more fun (like night and day) in bike world, its like comparing a GSXR 1000 (stand up) to a Honda Shadow 750(sit down)
As for models, if you want a cheap, reliable, easy to fix, plenty of parts available sit down ski, I would buy a Yamaha XL700, any year, its the most bullet proof ski ever built. Just about every rental fleet in the US uses them as there base ski. yes its only a 700cc and its probley pushing 80-90hp BUT, fuel mileage is great, parts are easy to find, its the most reliable ski on the market.
Yamaha designed them specifically for the rental market, they are not much to look at, no fancy features etc..
And if u want to save big money go to the US to buy one, lots for sale in upstate new york or even detroit-st clair lake etc.. area, there is no RIV for jet skiis, only the trailer (if you need it).
