Cutlass Bearing Replacement, 1985 Najad 343
At the aft end of the shaft log, you should see the end of a bronze sleeve, with a synthetic, ribbed liner, and on one side, probably, a set screw radial to the sleeve. Loosen the set screw and saw the sleeve from the inside out an inch or so on either side, then pry that piece out. One more cut in the remaining piece will allow you to get the remainder out. Very tedious work. See if you can attack it with a sprocket puller/aka bearing puller. I''ve never been lucky enough to be able to work that.
