I have a 1967 3.9 Merc o/b The bearing housing is cracked. I need to replace the bearing housing and oil seals, etc. The lower end oil leaked out. I took the prop off. There is a keyed ring that is screwed into the lower end unit. Where can I find a tool to remove this ring? How do I exactly replace this oil seal? This is a good running motor. However, the labor to fix it is way more then the motor is worth. I have to do to work myself!! Thanks
