 noise in shaft
I am getting a noise from my shaft. A knocking sound, but no more vibration than normal. Seems to happen when turing in one direction at fun speed. Didn't see any new dings in prop, May have bent shaft, but didn't hit anything. Any ideas?
It's a 35 hp MB extra long tail for tall transom.

 Re: noise in shaft
I've only got 28hr on this motor. Hope it's not bearing, how can I check them? Had a GD before without bearings.

 Re: noise in shaft
add more grease and see if that helps dampen the noise up
