Hey there. I am in the need of a little advice. My in-laws have a metal (steel??) rowboat and I am interested in hooking up an electric trolling motor to it to use as the main motor. Problem is, I have no idea what size or brand to get (the lake they live on is an electric motor only lake). The boat is about 17ft in length, with a square-type front (that is the bow, right?). I am interested in mounting it on the back of the boat. I was thinking about getting a 55lb thrust, since that is the largest I can seem to find that is a 12v, but would that be too big? Any suggestions for a set-up would be greatly appreciated. Thanks in advance.
