Stupid question: I'm trying to pick a trolling motor for the first time to go on an old boat. When the shaft measurement is advertised, is it A or B? (see image). I'm sure it's A but I want to be sure.
Correct me if I'm wrong guys. But I'm thinking B. Reason being is most trolling motor can adjust up or down from the mounting bracket by loosening the nob and adjusting from there. Don't take my word for it though lol.
