Vibration on high speed

[fca951]

I removed the rear engine support and put a new one then I when to test my gtx 951, I start the engine and always wait like 1 minute before I press the throttle but something got pulled by the impeller then expelled, then when i ride at low speed between 0 and 35 it all good but when i go faster I feel the vibration on the impeller, dont know if i need to align the engine or is the impeller damaged cuz it happened before I could test the jetski with the new engine support

Somebody has an idea???

Do you have a drive shaft alignment tool? That would tell you if the engine is set properly, but from the pics that impeller is probably unbalanced. Again hard to tell in the picture but if there are a bunch of chunks taken out of the wear ring that could be causing your issue as well.

I think your impeller is kinda gone. I see major wear (or bent?) on the top propeller. Not surprised it would be unbalanced.

Thanks!! I will look for a new impeller

ya, i'm leaning towards impeller as well, but if this wasn't an issue before replacing the bracket, then it would be advisable to verify that engine is properly aligned.

I tought that if was the aligment it will be vibrating at low speed not only at high

Your wear ring is also shot.

If you removed any of the engine mounts the engine has to be realigned.

I also agree that the top blade on the impeller is bent. You don't have to replace it you can send it to Skat-Trak for refurbishment.

That wearing was shot 6 months ago.
