I have never owned a PWC before and could use some advice. Someone is selling the above but haven't used them for 2 seasons. Have there been any major problems with these, motor wise, fuel injection, etc.?
I don't believe so. I think you will have to do some good maintenance on them to get them running again. Carbs will have to be taken apart and cleaned, new plugs, etc. But they should be perfectly fine. Check compression on the cylinders though. 150 is normal and anything above 100psi is still ok. Under 100 needs a rebuild. The cylinders should be more than 5-7 psi apart.
