Big problem with my Sea Doo. Need HELP!

[Mariuz]

Hello,

I'm Marius, and i'm from Romania. I have a problem with my Sea Doo Bombardier 717 LE 2004.
I was at all boat services with my problem and i don't have any good answer. You can hear the sound of jetski and i cant accelerate!
Maybe can i get some help from you and finally put my jetski on water.
Please help me!

Have you checked the timing? And did you make sure she's getting fuel?

Sounds like your rotary valve timing is off/the valve timing is not consistant. Pull the RV cover off and see how much slop there is in the rotary valve shaft, you might have stripped the brass gear. Spin the rv shaft by hand, you should only have a few degrees of rotation.
