I have a 12' flat bottom boat and a 1.5hp 30lb thrust trolling motor. I went to the river. Went down the river and went to turn around and I couldn't get back up the river. The dam had 3 turbines on. All I had in The boat was floats, paddles, me, one other person, battery, trolling motor. Is the trolling motor to small or was I supposed to have the trolling motor all the way into the water? Thanks in advance
