Trolling motor

A trolling motor is a self-contained marine propulsion unit that includes an electric motor, propeller and control system, and is affixed to an angler's boat, either at the bow or stern. A gasoline-powered outboard used in trolling, if it is not the vessel's primary source of propulsion, may also be referred to as a trolling motor. The main function of trolling motors is to keep the boat running at a consistent, low speed suitable for trolling. Trolling motors are often lifted from the water to reduce drag when the boat's primary engine is in operation.
