Abstract
A device is provided for attachment to the submerged portion of an electric trolling motor to serve as a rudder and to further provide quieter operation and resistance to fouling by aquatic vegetation. The device, which may be of integral or two piece construction, attaches to the vertically disposed control shaft of the trolling motor and further embraces the drive unit of the motor. An upper section of the device has opposed side walls of large area, thereby providing a rudder effect.
