2005 GTX 215 no power and runs rough

[95xpyellow]

Hey. 2005 GTX super charged 215. Ran fine one day, next it was hard to start, runs rough and loud and has almost no power. Stops running after about 45 seconds. Pulled the plugs and they wernt too bad, put some used ones in from last year that are fine and it ran the same. Checked intake and it’s clear. Fuel is premium and fresh. Have another ski that I fueled the same time and it is fine. Any ideas.

Check supercharger. When was it rebuilt last?

It has 2 summers on it. Maybe 40-60 hours

Sounds like you have a drag on the engine which can be a supercharger bearing, pump bearing, engine bearing, etc.

Makes sense. I’ll start digging into it and see what I can find.
