[Public-List] Stern Tube Bedding

[George Dinwiddie]

Andrew,

I used 5200 to reinstall my stern tube. When doing so, I put some 
vaseline on the cutless bearing housing threads and where it would 
contact the 5200 around the stern tube. This was to keep it from 
sticking to the stern tube 5200.

When reinstalling the cutless bearing housing, I also bedded it with 
5200, but I wanted that to be a different blob of 5200 since it's 
removed more often than the stern tube.

BTW, when you need to remove the 5200ed cutless bearing housing, a 
little heat with a propane torch softens the 5200.

Perhaps in your case there it 5200 on the threads. You might try putting 
the cutless bearing housing in a vice, heating it at the joint with a 
propane torch, and turning the stern tube with a pipe wrench. Either 
caulk or corrosion is probably holding it.

I don't worry about the cutless bearing bolts stripping out. I also put 
5200 on them when reinstalling.
