2003 GTX 4 Tec- Not Performing

[seanmay27]

I am having some trouble with my seadoo. It takes a bit for it to get up to speed and you really have to floor it. Even then it's not reaching its top speed. Also when I have a rider or even try towing someone it will not get over 10 mph and I get the high engine temperature light on. There is nothing in the intake grate, its all clear. I already replaced the impellar wear ring. Any other suggestions

Pull the intake hose off and try to spin the supercharger impeller. If it spins freely the s/c is junk and needs rebuilding. How many hrs on it and did you ever upgrade the ceramic washers on the s/c?

Seconding jwalts. Do a search for supercharger failure on here and you'll see a ton of threads that can help out as well.
