Ginbal Bearing Growling...

[stnick]

Merc 350cid 260 h/p. Had new Gimbal bearing installed while I was waiting on my new SEI drive. While idling, loud "growl" can be heard and felt. As soon as I shift into fwd or rev. sound goes away.The mechanic said my "upper" was what he "thought" it was. I don't see how the upper would only whine or growl in neutral. <br />Help to diagnose.<br />Thanks,<br />Nick

When in neutral, the upper is still working. When in gear, load from the lower may quiet the noise.<br />Check the gear lube for metal and see what the lube looks like.<br />Pull the drive and recheck the gimbal bearing and don't forget the ujoints. They can cause the noise also.
