I know this is a few years old, but I’ll join the fun because I think I have the same motor. It was sold to me as a “1960 27.7HP” but I think, based on more reading, that it’s a 25HP. No matter, it’s going behind a 13′ boat so it’s overkill no matter what.
I have electric AND recoil start but no charging circuit. Im working on adding an independent charging circuit (unless someone can tell me how to thieve voltage from the mag coils).
This is my first outboard and it’s been fun to tinker with.
