2000 sea doo challenger won't go over 3,000 rpm in water only and stalls.

[TwinRiversTubing]

I have a 2000 sea doo 1800 challenger stalls out around 3000 rpm's in water only. Challenger is only equipped with a single engine. I have it to 2 different sea doo dealers with no luck. 1 dealer had rebuilt carbs. Put back in water and still same issue. Took it back to dealer and now they tell me it needs engine. They said they believe seal between crankshaft is blown. Second dealer does not believe it needs engine. Second dealer rechecked carb rebuild, pop off pressure and fuel supply. Second dealer gave up and has no idea what is wrong. Please help!

You have a merc engine? In reality any standard boat shop that works on mercruisers should work on your boat but most see seadoo and won't touch it. That is the only main issue I see when seadoo went to mercs for a few years.
