[Public-List] Cutlas bearing help please ~ PS

You will need to unscrew the cutlass bearing housing from the stern tube to 
get the cutlass bearing out before caulking. When out - just take it to a 
machine shop - so much easier that way and make sure they drill for water 
cooling and don't forget to remove the two small set screws on the side.

Nice and slow - two people. One inside one out side.

Best of luck.
