Engine runs and revs but no thrust.

[Kuikkis]

Hi everyone!

I have a tricky problem with my Sea Doo GTI -98 PWC. I was riding in a deep water with slow speed when I heard a cracking sound from my Sea Doo. Engine kept running and it revved but there wasn´t thrust at all.

I have now replaced my wear ring and impeller and checked driveshaft splines (both ends are fine) but still same problem occurs. What can be the root cause here if engine runs and revs but it doesn´t generate thrust..

You don´t know how much I would appreciate your help with this.

I´m very new with PWCs and would like to keep driving mine but it´s been since May when my Sea Doo broke down..

Sounds like Internal engine problem

Sounds like Internal engine problem

yes, it sounds like that to me as well.. I just don´t know what can brake like that.

Check pistons pressure!
Maybe a bad ring, carburation can make loss thrust too

Check your pto. It sounds like it stripped out.

I would think it has to be that or your drive shaft.
