Abstract
A permanent magnet direct-current gearhead motor is supported by a base member so that its output gear motion is transmitted to a splined steering shaft which descends and is attached to the electric trolling motor itself. The transmission of motion between the gearhead motor and the spline gear on the upper end of the steering shaft may utilize a larger intermediate gear so that limit switches can be installed thereon to limit the range of rotation of the gears, and thus of the trolling motor itself. The direction of the gearhead motor rotation is dependent on the polarity of the direct current applied; the desired polarity being established through by button-type switches connected through a double throw, double pole direct current relay which is housed on the base member, adjacent to the gearhead motor. The button switches may be positioned at a multiple number of different locations within the boat, wherever desired. A preferred triangular three button switch arrangement is utilized wherein two buttons are used to change the direction of the motor and the third button used as an on-off switch for the operation of the trolling motor itself. A pointer, which indicates the directi…
