A trolling motor automatic disconnect interrupts power to a trolling motor and controller from an electrical power source when the trolling motor is not in a trolling position. A relay operated switch between the trolling motor and controller and the power source connects and disconnects the trolling motor and controller to and from the power source. Contacts mounted on and inserted into and withdrawn from the water with an immersible portion of the trolling motor sense when the immersible portion of the trolling motor is disposed in the water. An inverting amplifier responsive to the status of the contacts energizes the relay to pull the switch to the connect condition when the immersible portion of the trolling motor is disposed in the water and deenergize the relay to pull the switch to the disconnect condition when the immersible portion of the trolling motor is not in the water. A time delay circuit maintains the energization of the relay to hold the switch in the connect condition for a predetermined time after the immersible portion of the trolling motor is removed from the water so that power to the motor is not interrupted due to the propeller momentarily and unintentionally leaving the water. Alternatively, a mercury switch or mechanical disconnect mounted on the motor may replace the contacts so that when the motor is not in a stored condition, the inverting amplifier will energize the relay, and when the motor is in a stored condition, the inverting amplifier will disengage the relay.
