Evaluating the Results of the Autopilot Configuration

When the Dockside and Sea Trial Wizards are complete, test the autopilot to be sure it is configured correctly. Test the autopilot first at slow speeds (below planing), and then test the autopilot at planing speeds.

To test the autopilot configuration:

1.Drive the boat in one direction with the autopilot engaged (heading hold). The boat should not oscillate significantly; however, a small amount of oscillation is normal.

2.Turn the boat in one direction using the autopilot. When you release the turn button, the boat should overshoot the turn and quickly correct the heading to the point at which you released the button. You will notice that the faster you are going, the greater the boat will overshoot the turn.

3.If the autopilot is configured properly at slow speeds, repeat these tests at planing speed, and vice versa.

To adjust the autopilot configuration if necessary:

1.If you feel that the heading hold oscillates significantly or that the autopilot does not quickly correct the heading when turning, you can make slight adjustments to the rudder gain.

Note: When you manually adjust the rudder gain (or counter gain), make small adjustments, and adjust only one value at a time. Test the change before entering any further adjustments.

2.On the GHC 10, select Menu > Setup > Dealer Autopilot Configuration > Turn Fine Tuning Setup > Rudder Gains to access the rudder gain adjustments. There are two types of gain settings at both low and high speeds:

•Rudder Gain—Adjusts how tightly the rudder holds the heading and makes turns. If you set this value too high, the autopilot may be overactive, attempting to constantly adjust the heading at the slightest deviation. An overactive autopilot can cause excess wear and tear on the autopilot pump.

•Counter Gain—Adjusts how tightly the rudder corrects the turn overshoot. If you set this value too high, the autopilot can overshoot the turn again when attempting to counter the original turn.
