watercraft chugging take off acceleration

My 1999 Sea Doo GTX RFI has approximately 100 hours on its powerplant. The problem is that on initial acceleration, either while I'm alone or when pulling a wakeboarder, the machine does not have smooth, crisp transition through the powerband. on take off, it appears to be labored acceleration. However, when the machine begins to plane, everybody is happy. Is there an easy fix for this?

Craig,
The GTX RFI has a Rotax Adjustable Variable Exhaust (RAVE) system. If the RAVE valve gets stuck open, you can experience a rough take off Sea Doo recommends annual cleaning to remove carbon, However, other things, like clogged injectors and the need for TPS adjustment, can also cause the problem you described.
