Not sure if my experience applies to a Seadoo?... I had a sailboat in San Diego for years.
Bought it new.... took delivery everything seemed to be working great, then a few months later, while motoring up to Oceanside CA. the engine quit, I checked and found the glass bowl(s) on the fuel lines full of rust particles. I had to empty these rust particles numerous *#&% times just to make it back to my slip,...
The dealer determined that the deck mounted gas cap did not seal tight, and some salt water had worked it's way into my fuel tank and caused quite a bit of corrosion. They pulled the tank and corrected the rust problem under warranty.
Again, I am not sure what your fuel system consists of, most likely polly / plastic, my only point is, if any part of your tank or filler neck / drain assembly is metal, you may wind up with some rust issues down the road.
Just thought this might be something worth checking into?
