Hello...Help I have to replace my cutlass bearing on my 1981 H27. The boat has origional 1GM and trans+shaft. Boat is in water and job will be done by diver. I understand the bearing/bushing is 2 parts, an outer brass sleve with a inner bushing inserted into strut. My diver has the correct tool to do work. Does anyone have a part # or source? Does anyone know outer diameter of assembly? Does anyone know correct length of bushing/bearing?
