adm1476, That question really needs further info. Exactly what type trolling do you do? If you are planning to troll along the banks and structure and fish that way, it takes so little to move along slowly. However, if you plan on trolling open waters with high currents and/or winds, then that takes a lot of umph. So the answer depends on what you want the trolling motor to do. I use to troll in a Bass Boat down banks fishing for bass with a mere 20 - 30 lb trolling motor. And it was way adequate for that. JMHO!
