What kind of grease should I be using on the shift cam on 1956 mark 55? It takes a lot of muscle to get’er into reverse. I been using regular marine grease. Once it’s in gear it works like it should. Gear oil is OK. Maybe it needs lubraplate?

Ya my gear case is fine! It is the reverse cam that I am talking about. I put some corn head grease in that cam pocket and worked the L out of it. It is still plenty stiff. Maybe I should start lifting weights!

DROP THE LOWWER AND CLEAN THE CAMS AND GREASE THEM. MAKE SURE THE ROD AND REVERSE LOCKS ARE MOVIBG EASILY.
