Autopilot
You can use the autopilot feature only at a station installed next
to a helm, throttle, and helm control device.
You are responsible for the safe and prudent operation of your
vessel. The autopilot is a tool that enhances your capability to
operate your boat. It does not relieve you of the responsibility of
safely operating your boat. Avoid navigational hazards and
never leave the helm unattended.
Always be prepared to promptly regain manual control of your
boat.
Learn to operate the autopilot on calm and hazard-free open
water.
Use caution when operating the autopilot near hazards in the
water, such as docks, pilings, and other boats.
The autopilot system continuously adjusts the steering of your
boat to maintain a constant heading (heading hold). The system
also allows manual steering and several modes of automatic-
steering functions and patterns.
Opening the Autopilot Screen
Before you can open the autopilot screen, you must have a
compatible autopilot installed and configured.

Selecting a higher percentage reduces rudder activity and
heading performance. The higher the percentage, the more
the course deviates before the autopilot corrects it.
TIP: In choppy conditions at low speeds, increasing the
Power Saver percentage reduces rudder activity.

steering systems.
