Outdrive Knock

Rinker 342. Twin 6.2 mercruises. 2002 model. Bravo 3 outdrive.

Had a knock on the port side, very faint, replaced ujoints, no issues on that side now. Prior, no issues on starboard.... When put back into the water, starboard started to knock VERY loud when turning over 3/4 either direction, whether in gear or neutral. Replaced gimbal bearing on that side and all u joints, aligned engine as it was out of alignment....STILL knocking....im at a loss, what could it be? Any thoughts.

Thanks!!

Pop the top off the outdrive, take a look.

I had the same thing after the mechanic replaced transom asy. He said he aligned engine with bar. Took boat back to the shop and he spent another 3 hours realigning and now...no knock!!

Said he had to shim the back engine mounts

@skuter99 good info. Something must have been hitting. All your new parts would have been ruined.

Hmm, so you think it may be out of align still? its weird that it didnt do it until pulled. Did that maybe put stress on the drive and cause an issue. Gimbal and u Joints were all changed.
