GHP 10V Installation Instructions

Configuring the GHP 10V

The GHP 10V must be configured and tuned to your boat dynamics 

and motor configuration. Use the Sea Trial Wizard on the GHC 10 

to configure the GHP 10V. These wizards will walk you through the 

necessary configuration steps.

about the Sea trial Wizard

The Sea Trial Wizard configures the fundamental sensors on the 

autopilot, and it is extremely important to complete the wizard in 

conditions appropriate for your boat.

Important Sea trial Wizard Considerations

Complete the Sea Trial Wizard in calm water. The nature of calm water 

is relative to the size and shape of your boat.
•  Ensure your boat does not rock while sitting still or moving very 

slowly. 

•  Ensure your boat is not significantly affected by the wind.
• 

Keep the weight on your boat balanced. DO NOT move around 

on the boat while completing any of the steps in the Sea Trial 

Wizard

.

Starting the Sea trial Wizard

Before you start the Sea Trial Wizard, you must drive to an open area of 

calm water.
1.  Turn on the GHP 10V.
2.  Select an option:

•  If the Sea Trial Wizard starts automatically, proceed to step 3.
•  If the Sea Trial Wizard does not start automatically, select 

Menu

Begin

.

Performing the Sea trial Wizard

1.  Drive your boat to an open area of calm water.
2.  Start the Sea Trial Wizard (

page 11

).

3.  Configure the planing RPM (

page 11

).

4.  Calibrate the compass (

page 11

).

5.  Perform the autotune procedure (

page 11

).

6.  Set north (

page 11

).

7.  If necessary, set the fine heading adjustment (

page 11

).

Configuring the Planing RPM

1.  Note the RPM reading from the tachometer on the dashboard of 

your boat at the point your boat transitions from displacement to 

planing speed.

2.  If the tachometer value does not match the value on the GHC 10, 

use the arrows to adjust the value. 

3.  Select 

Done

.

Calibrating the Compass

1.  Drive your boat at slow/idle 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 flat

 as possible.

 

Turn slowly so that the boat DOES NOT list

.

  The GHC 10 displays a completion message when the calibration is 

complete.

4.  Select an option:

•  If the calibration completes successfully, select 

Done

•  If the calibration fails, select 

Retry

 and repeat steps 1–3.

Performing the autotune Procedure

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

stretch of open water available.
1.  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 10 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

.

4.  If autotune fails, 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.

Setting north

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

free, open water available.
This procedure appears only if you connect an optional GPS device to 

the GHP 10V (

page 10

), and the device has acquired a GPS position. If 

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

fine heading adjustment (

page 11

).

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

Begin

.

  The GHC 10 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.

Setting the Fine Heading adjustment

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

connected to the GHP 10V (

page 10

). If you do have a GPS device 

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

set north instead (

page 11

).

1.  Using a handheld compass, identify north.
2.  Adjust the fine heading setting until it matches north on the 

magnetic compass.

3.  Select 

Done

.

Evaluating the Results of the autopilot 

Configuration

1. Test the autopilot at a slow speed.
2. If necessary, adjust the gain setting (

page 12

).

3. Test the autopilot at a higher speed (normal operating conditions).
4. If necessary, adjust the gain and acceleration limiter settings.
