Hey I am gathering parts for my overhaul of the engine and I have noted that the outdrive needs some work too. This is a 1990 Sea Ray with a 4.3. What are the things I need to look for on this drive to tell me if it is R MR Alpha GenI etc.... There are no serial #'s left on the stickers!!! Help! Oh yea, it does not have the lifting ring on top of the vertical access shaft cover if that helps.
