I have a 99 waverunner 1200 XL Lmtd. While at the lake the ski would run ok for a while then lose power and only run at about 20 mph. It did the same thing when the cat con failed. We gutted the cat and it ran fine.
Removed the cat at the lake and it was full of water.
While cat was off we ran the engine and water was coming out of the exhaust in three streams.
I have removed the first two sections of exhaust after the manifold and there are no cracks. next section looks difficult to remove so I thought I would ask for advise first.

Could there be a valve that has failed and is allowing water into the cat or is water in the cat normal?

Did I mention that I don't know squat about working on PWCs?
