A rudder reference sensor tells your autopilot exactly where the boat is pointed so it does not overcorrect during rough swells. If your tiller arm feels loose or the system kicks off while you are trying to hold a steady course, the sensor might have slipped or reached the end of its life. These small parts keep the pilot aligned with your actual direction, preventing the motor from grinding against the stops. Check the physical mounting base and the linkage arm connection to make sure you pick the right replacement for your specific drive unit.
