Hesitation from a stand still 787

[Jaxtoce1]

This description isn't very clear.



Does the engine bog down and try to die?
Or, does the engine rev right up and the Sea-Doo is slow to react?
These are two different symptoms that require completely different diagnosis and repair. You mentioned that you have a bad impeller and you lost top speed so I assume it's the latter. Repair your impeller and check the wear ring for damage, replace it if necessary. It's cavitating severely.

It's not cavitating your reading it wrong.. when taking off from a standstill the motor will bog not as if it's dying but just bog and then take off.. I'll try to explain in terms of RPM's... it idles in the water around 1500rpms... if I hit the gas just idling forward.... it will drop to about 12-1300 rpms (bog) then take off and jump straight to about 6600 rpms, when it does this the ski itself also takes off, thus eliminating the suspicion of the wear ring/impeller being a problem...

Hope this clears things up, lmk if I can clarify anymore, like I said when I get out tomorrow I will gps the speed... I guess maybe I'll hope that the speedo is just reading wrong
