I have a 1985 Skeeter Starfire 175 with a front mounted trolling motor (Minncota at55). This is my first boat (I bought it used) and it seem s that the switch on the bow marked 12/24 for the trolling motor is broken. I have two batteries that I manually charge and must switch between using jumper cables when trolling. A. can anyone tell me what this switch is supposed to do and how it works and B. can anyone tell me the best way to fix it. I am really good with repairs but this one has me confused. The boat runs great (1983 Mercury Balck Max) although it seems i have the wrong sized prop on it. I can't get my RPMs up high enough and it is a little slow getting out of the hole. I am learning and boy it is fun. Any help would be much appreciated.
