RXTX Slow Accelerating

[KJurgelewicz]

I have a 2008 RXT-X and starting today it is extremely slow to accelerate. Feels like it is accelerating through mud. Once it gets up to 35+ it seems to be slightly better. Engine won't get up over 5600-5800 RPMs. Engine doesn't sound normal either. Nothing is caught in jet drive. Any one have ideas I can look for?

Yep,, Sounds like a intercoolor and or SC issue.

Check he hoses out first. Look for cracks, loose clamps or the hose simply off the connections.

Remove the hose at the SC and see how easy it is to spin the SC. If it is easy, it is toast.

Has it ever been rebuilt? Some of the early 08 skis had the ceramic washers still, (I think it was an old stock kind of thing).
