GHP 10 Marine Autopilot System Installation Instructions

Setting

Description

Tachometer Setup

Verify Tachometer

With the engine (or engines) running, compare the RPM readings on the 

GHC 10 with the tachometer on the dashboard of your boat. Adjust the 

Pulses Per Rev 

with the arrows if the values do not match, and then 

select 

Done

. When you adjust the 

Pulses Per Rev 

with the arrows, there 

is a delay before the new RPM readings appear on the GHC 10. For each 

adjustment, be sure to wait until the GHC 10 adjusts to the new reading. 

Tachometer Setup

RPM Source

Select the engine (or engines) to which you wired the tachometer sensor 

from the CCU. If you connected a NMEA 2000-compatible engine to the 

NMEA 2000 network, select 

nMEA 2000

. For a single-engine boat, select 

port.

Tachometer Setup

Planing RPM

Take note of the RPM reading from the tachometer on the dashboard of 

your boat at the point your boat transitions from displacement to planing 

speed. If the value does not match the value on the GHC 10, use the 

arrows to adjust the value.

Tachometer Setup

Low RPM Limit

Take note of the RPM reading from the tachometer on the dashboard of 

your boat at the lowest RPM point. If the value does not match the value 

on the GHC 10, use the arrows to adjust the value.

Tachometer Setup

High RPM Limit

Take note of the RPM reading from the tachometer on the dashboard of 

your boat at the highest RPM point. If the value does not match the value 

on the GHC 10, use the arrows to adjust the value.

Hydraulic Setup

Helm Displacement

The helm displacement is usually written on the body of the helm pump. 

If you are unsure, consult the manufacturer of your boat for the helm 

displacement value. Use the arrows on the GHC 10 to enter the helm 

displacement value.

Hydraulic Setup

Lock to Lock Turns

Count the number of turns it takes your helm to go from lock to lock (fully 

turned port to fully turned starboard). Use the arrows on the GHC 10 to 

enter the value you counted.

Hydraulic Setup

Verify Steering Direction

Use the arrows on the GHC 10 to test the steering direction. When you 

push the right arrow, the motor should turn the boat to the right, and vice 

versa. Determine if the engines are steering in the correct direction and 

press 

Continue

. Use the GHC 10 to answer the questions.

Hydraulic Setup

Linkage Compensation

Adjust the linkage compensation if the steering is loose or sloppy. The 

higher you set this value, the more the autopilot compensates for loose or 

sloppy steering. Use this setting with caution.

Turn Fine Tuning Setup > Rudder Gains

Low Speed

Set the rudder gain for low speeds.

Turn Fine Tuning Setup > Rudder Gains

Low Speed Counter

Set the rudder gain counter-correction for low speeds.

Turn Fine Tuning Setup > Rudder Gains

High Speed

Set the rudder gain for high speeds.

Turn Fine Tuning Setup > Rudder Gains

High Speed Counter

Set the rudder gain counter-correction for high speeds.

Turn Fine Tuning Setup

Acceleration Limiter

Limit the aggressiveness of autopilot-controlled turns. Increase the 

percentage to limit the turn rate, and decrease the percentage to allow 

higher turn rates.

Navigation Setup

Fine Heading Adjustment

Increase or decrease to fine-tune the autopilot heading.

Navigation Setup > NMEA Setup

NMEA Checksum

If the connected GPS unit incorrectly calculates checksums, you may 

still be able to use it if you turn this setting off. When off, data integrity is 

compromised.

Navigation Setup > NMEA Setup

Reversed XTE

If the connected GPS unit sends the incorrect steering direction with the 

cross track error signal, use this setting to correct the steering direction.

Navigation Setup

Navigation Gain

Because the cross track error data transmitted by a NMEA 0183 GPS 

device is only accurate within .01 mile (60 ft.), the gain may need 

adjustment. Increase this setting until the boat oscillates back and forth 

near the course line, then lower it a few levels.

Navigation Setup

Navigation Trim Gain

After adjusting the Navigation gain, increase this setting until you can see 

the standoff from the course line decreasing over time.

note:

 Certain configuration settings are available when using the GHC 10 normally, such as enabling and disabling the Shadow 

Drive, adjusting the sensitivity of the Shadow Drive, and adjusting the Sea State Filtering setting. See the configuration section of the 

GHP 10/GHC 10 Quick Start Manual for more information.
