I rode my first jet ski in May of this year (I'm 51) and I'm hooked! I bought a 2000 Sea Doo LRV and we love it. Unfortunately, I was pulling the tube on Saturday and something went "clunk". I stopped, shut down, did a quick inspection and fired it up (it started normally). I found that it wouldn't go faster than 6-8 MPH. The engine ran normally but even when tached to 4-5K RPM it wouldn't go faster than 6-8 MPH. I was able to run it the 3 or so miles to the ramp and get it out of the water. The dealer is telling me that it might be some sort of ring in the drive train? Thoughts?
