Abstract
A control circuit for a direct current trolling motor powered by a storage battery includes a transistor placed in series between the motor and the battery, a selector switch, and one or more voltage regulating devices such as zener diodes. The selector switch includes a movable or wiper element connected to the battery, and a plurality of contacts, one of which connects the battery directly to the motor, and one of which is unconnected. At least one contact is connected to a zener diode connected to the base terminal of the transistor, to regulate the speed of the motor in a stepwise manner.
