I currently have a 16 ft bow rider mini xtaski boat and would like to fit a trolling motor to it. But i have not idea on what size and strenth to buy. I also have no idea if it should be 12v or 24v and what plans need to be made regarding my current battery and if i need to add another one. The motor will be a foot control and bow mounted motor. Please any help will come in handy!
