A foot pedal device for controlling an electric steer trolling motor and navigating a marine vessel. The foot pedal allows proportional control of the vessel such that the operator's foot movement on the foot pedal is proportional to an action by the trolling motor. The foot pedal includes a platform that pivots upon a base, an angular position monitor, and a controller; the controller is communicatively coupled to the angular position monitor and is configured to receive an angular measurement from the magnetic angle sensor and generate at least one control signal for a trolling motor of a marine vessel at least partially based on the angular measurement from the sensor.
