

1. Drive your boat at cruising speed in a straight line.

2. Select Begin, and continue to drive in a straight line.

3. When instructed, turn the boat slowly clockwise, taking care to

make the turn as steady and at as possible.

Turn slowly so that the boat DOES NOT list.

After you successfully complete the calibration, the GHC 20

displays a completion message.

4. Select an option:

• If the calibration completes successfully, select Done.

• If the calibration fails, select Retry and repeat steps 1–3.

Before you can perform the autotune procedure, you must have a large

stretch of open water available.

1. If you have a non-planing vessel, adjust the throttle so the boat

travels at a typical cruising speed that provides responsive steering.

If you have a planing vessel, adjust the throttle so the boat travels

below planing speed.

2. Select Begin.

The boat performs a number of zigzag motions while the Autotuning

is in progress.

The GHC 20 displays a completion message.

3. Select an option:

• If the autotune completed successfully, select Done and take

manual control of the boat.

• If the autotune failed, adjust the throttle and select Retry

Autotune.

• If the autotune failed, and the rudder went hard over or the boat

went in a circle, select Reverse Steering Dir. and Retry.

• If you receive an Error: ECU Drive Circuit Overload. See

manual for tips on reducing load error message, see the tips on

page 17.

4. If autotune fails again, repeat steps 1–3 until the autotune completes

successfully.

5. If the autotune procedure continues to fail after you reach maximum

cruising speed, reduce your speed to the initial autotune speed

and select Alternate Autotune to begin an alternate autotuning

procedure.

Before you can set north, you must have at least 45 seconds of hazard-

free, open water available.

This procedure appears if you connect an optional GPS device to the

GHP 10 (page 14), and the device has acquired a GPS position. If you

do not have a GPS device connected, you are prompted to set the ne

heading adjustment (page 16).

1. Drive the boat in a straight line at cruising speed, and select Begin.

The GHC 20 displays a completion message when the calibration is

compete.

2. Select an option:

• If the calibration completed successfully, select Done.

• If the calibration failed, repeat steps 1–2.

This procedure appears only if you do not have an optional GPS device

connected to the GHP 10 (page 14). If you do have a GPS device

installed on your boat that has acquired a GPS position, are prompted to

set north instead (page 16).

1. Using a handheld compass, identify north.

2. Adjust the ne heading setting until it matches north on the

magnetic compass.

3. Select Done.

1. Test the autopilot at a slow speed.

2. If necessary, adjust the gain setting (page 17).

3. If you receive an Error: ECU Drive Circuit Overload. See manual

for tips on reducing load error message, see the tips on page 17.

4. Test the autopilot at a higher speed (normal operating conditions).

5. If necessary, adjust the gain and acceleration limiter settings.

1. Drive the boat in one direction with the autopilot engaged (heading

hold).

The boat should not oscillate signicantly; however, a small amount

of oscillation is normal.

2. Turn the boat in one direction using the autopilot and observe the

behavior.

The boat should turn smoothly, not too quickly or too slowly.

When you turn the boat using the autopilot, the boat should

approach and settle on the desired heading with minimal overshoot

and oscillation.

3. Select an option:

• If the boat turns too quickly or too sluggishly, adjust the

autopilot acceleration limiter (page 16).

• If the heading hold oscillates signicantly or the boat does not

correct when turning, adjust the autopilot gain (page 17).

• If you receive an Error: ECU Drive Circuit Overload. See

manual for tips on reducing load error message, see the tips on

page 17.

• If the boat turns smoothly, the heading hold oscillates only

slightly or not at all, and the boat adjusts the heading correctly,

proceed to step 5.

4. Repeat steps 2 and 3 until the boat turns smoothly the heading hold

oscillates only slightly or not at all, and the boat adjusts the heading

correctly.

5. For planing vessels, repeat steps 1–4 at faster speeds (page 16).

NOTE: When you manually adjust the acceleration limiter, make

relatively small adjustments. Test the change before making additional

adjustments.

1. Enable the advanced conguration procedure (page 17).

2. On the GHC 20, select Menu > Setup > Dealer Autopilot

Conguration > Autopilot Tuning > Acceleration Limiter.

3. Select an option:

• Increase the setting if the autopilot turns too quickly,

• Decrease the setting if the autopilot turns too slowly.

4. Test the autopilot conguration.

5. Repeat steps 2 and 3 until the GHP 10 performance is satisfactory.
