The present system is a system for controlling a trolling motor in a fishing boat. The system comprises a transmitting unit and a receiving unit. The transmitting unit includes a direction sensor, a selection switch, and a transmitter. The direction sensor automatically senses the direction to which the user desires to steer the fishing boat when the user points the direction sensor in that direction. The user then uses the selection switch, and by "clicking" the switch once the transmitter sends a signal with the direction information to the receiving unit. The receiving unit then receives the signal containing the direction information, and affects the trolling motor in such a way that it steers the fishing boat in the desired direction.
