Yesterday I took the family out on our first sea trial.

As the day went on I noticed a knocking sound coming from the rear once I hit over 4K rpm. So I backed down. I hope all I need is bearing grease......It went away at lower RPMs.

Any suggestions?
Thanks,
Ollie

Remove the outdrive, check the ujoints and gimbal bearing.
