Is is possible that if you had 3 top crank shaft seals fail and now a lower unit that threw a gear, that maybe the crankshaft is out of balance or bent? Just not sure what could be causing my issues. Prop shaft is perfect.![]()

Anything is "possible"... but it would be easier to determine if it's "likely" if we could have a little more information:
What engine (preferably including the Serial #):
What WOT RPM are you achieving:
What PROP are you running:
