Abstract
Abstract A directional control mechanism for an electric trolling motor utilizes a plurality of foot pedal actuated switches to control a reversible directional control motor. A gear reduction unit connected to the directional control motor has an output shaft which rotates a drive pulley. A second pulley, connected to a rotatable trolling motor mounting shaft, is driven by a belt in engagement with the drive pulley. An electrical slip ring contact on the second pulley transmits current to the electric trolling motor. The trolling motor is also controlled by a switch activated by the foot pedal.
