This is 2400 rpm. Zoom in and look at the nut. It's moving a good 1/8 or more?
Hell it's probably been wobbling like this since I ran aground last summer and I just never noticed it. What made me pay attention was that the packing gland started leaking and I can't really seem to get it stopped.
I'm going to get a good boat mechanic to look at it hopefully. I just don't know enough to make the call.
All that packing gland goo on the bilge is new.
