I cant figure out what type of trolling motor would be best for my toon. The railing goes all the way out to the front of the deck. There is a little swinging gate in the center, but if I get one of the motors that folds up and lays flat like the bass boats have it will stick way inside the boat. Im afraid someone will step on it or something. But I do think that would be the best choice. How long of shaft do I need?
