The bronze race you see sticking out of the "shaft log", the fiberglass tube, is the cutlass bearing. the bearing is 5" long by 1 1/4" inside diameter by 2" outside diameter. The bearing on my 1978 382, hull # 53, did not have any set screws holding in in the shaft log. What held it in was knurling, cross hatch machining, on the outside of the bearing. That machining raised the surface of the bronze making for a tight fit. Any prop shop will have the ability to do the knurling. When putting the new bearing back into place, just smear the knurling with a caulking and push in in place. Do not use 5200 to coat the bearing.
To remove the old bearing, as long as you can see the bronze sticking out, just grab it with a large channellock pliers and start rotating. It should break free and start moving out. Am I right in assuming that you have dropped the rudder or moved the engine forward to remove the shaft?
