36 GHP 10 Marine Autopilot System Installation Instructions
Completing the Sea Trial Wizard:
Drive to calm, open water and, if the Sea Trial Wizard does not start automatically, select Menu > Setup > Dealer Autopilot
Conguration > Wizards > Sea Trial Wizard. The Sea Trial Wizard welcome screen appears on the GHC 10. Select Begin to start
the wizard.
Conguring the planing RPM:
1. Follow the directions on the GHC 10.
2. Note the RPM reading from the tachometer on the dashboard of your boat at the point your boat transitions from displacement to
planing speed.
3. If the tachometer value does not match the value on the GHC 10, use the arrows to adjust the value.
4. When you are nished, select Done.
NOTE: If you have a displacement-hull boat, there will not be a transition point for you to set. Instead, adjust the Planing RPM to
the highest possible value (6,000 RPM).
Calibrating the compass:
1. Before you begin the compass calibration procedure, drive your boat in a slow, straight line and wait for the wake generated by the
planing RPM conguration procedure to pass.
2. Select Begin.
3. When instructed, turn the boat slowly clockwise, taking care to make as steady and at a turn as possible. Turn slowly so that
the boat DOES NOT list.
NOTE: If you have a dual-engine boat, slowly run the port engine forward and the starboard engine in reverse to pivot on a
stationary position.
4. After you successfully complete the calibration, and the GHC 10 displays a completion message, select Done. If the calibration
fails, select Retry to begin the process again.
Performing the Autotune procedure:
1. Before you begin the Autotune procedure, adjust the throttle so that the boat travels at a constant RPM below planing speed, with
enough speed to maintain responsive steering.
2. Select Begin when you are ready.
3. The boat will perform a number of zigzag motions while the Autotuning is in progress.
4. When the GHC 10 displays a completion message, select Done. Be sure to take manual control of the boat when Autotuning
is complete.
If the Autotuning fails:
Increase the throttle approximately 200 RPM and select Retry to begin the process again.
If it fails again, continue retrying the process adding increments of 200 RPM.
If you reach planing speed through adding increments of 200 RPM and the autotune procedure continues to fail, reduce speed
below planing speed and select Alternate Autotune to begin an alternate autotuning procedure.
The Alternate Autotune is only applicable to a small number of boats, and should be the last attempt at autotuning. Do not perform the
Alternate Autotune until you are sure the standard autotune procedure will not work on your boat.
If the autotune procedure continually fails, it is possible that air is present in the hydraulic system. It is also possible that a
leak or other problem exists in the hydraulic system on your boat. If you cannot complete the autotune procedure or the Alternate
Autotune, check the hydraulic system for leaks or other problems, and bleed it completely if necessary.
Setting North:
1. To complete this step, you must have a large stretch of open water available. Be sure to have at least 45 seconds of hazard-free,
open water available while at planing speed.
2. Drive the boat in a straight line, at planing speed, and select Begin when you are ready.
3. When the GHC 10 displays a completion message, select Done. If the calibration fails, select Retry to begin the process again.
