Is a 24v 80lb trolling motor with spot lock enough thrust to hold a 16ft aluminum V hull boat still in the current on the river below the river park? Looking at a new trolling motor and would like to use spot lock but don’t want to spend the money if it’s going to just run the batteries way down. I’ve heard spot lock can drain the batteries. I don’t need it to hold in the super heavy current right below the dam. I normally fish down river a ways but there are still some areas that have decent strength current where I fish. A 36v system is out of the question for my boat. Too many batteries and I don’t have the money to spend on lithium’s in addition to a new Trolling motor. Thanks in advance for your opinions.
