Rudder Gain Settings
If you set these values too high or too low, the autopilot may become overactive, attempting to constantly adjust the heading at the slightest deviation. An overactive autopilot can cause excess wear on the actuator and drain the battery at a faster-than-normal rate.
On a helm control or the autopilot screen on a chartplotter, select
> Autopilot Setup > Autopilot Installation Setup > Autopilot Tuning > Rudder Gains.
