I bought a 1986 35hp merc that I just got running and will shift into reverse and neutral, but would not Go into forward drive. On further inspection, it appears that the shift shaft has a broken arm on it. The arm that has a washer in the iBoats picture has been sheered off. I’m wondering What that arm was attached to, and if there’s a lazy way I could fix this. Do I remove the power head and lower unit to fix this? I can’t find much help in the clymer online book.
