I just bought a 94 WaveRunner III. It runs like a scalded ape (that's good) for the first 20 minutes or so then it starts to hesitate and sputter. I think that it is overheating and some sort of rev limiter is kicking in. What do you think. How do I check to see if water is pumping well and getting to the engine. I would appreciate any help. Thanks in advance.

Are your cylinder head and exhaust cool still? Slightly warm? Sounds like the temp sensor on top of the cylinder head. Happened to me on a Tigershark, same symptoms. If in doubt, pull a couple hoses off and see if water is coming through when running.
