Boats do not tend to go in a straight line. Because of this, it is much easier to pull a boat than to push a boat. It is also easier to move the bow of the boat sideways compared to moving the transom. Therefore, a bow-mounted electric trolling motor allows for much greater boat control and positioning. If quick-response boat control and positioning is what you are looking for, a Minn Kota bow-mount electric trolling motor is a must.
Transom mount motors mount to the back of the boat with a clamp-on bracket and feature hand/tiller control. They are ideal for smaller boats, dinghies and canoes. They are also great for general positioning and standard trolling.
