GHP 12 Configuration Settings
Although all of the configuration is typically completed automatically through wizards, you can manually adjust any setting ( page 19 ).
NOTE : Depending upon the configuration of the autopilot, certain settings may not appear.
NOTE : On a powerboat, each time you change to the Speed Source setting, you must review the Verify Tachometer, Low RPM Limit, High RPM
Limit, Planing RPM, Planing Speed, or Max Speed settings, where applicable, prior to performing the autotune procedure ( page 17 ).

Autopilot Tuning > Rudder
Gains
(sailboat only)
Gain Allows you to adjust how tightly the rudder holds a 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 drive unit ( page 18 ).
Autopilot Tuning > Rudder
Gains
(sailboat only)
Counter Gain Allows you to adjust how tightly the rudder corrects turn overshoot.
If you set this value too high, the autopilot can overshoot the turn again when attempting to
counter the original turn ( page 18 ).
Autopilot Tuning > Rudder
Gains
(power boat only)
Low Speed Gain Allows you to set the rudder gain for low speeds.
This setting applies to the vessel when operating below planing speed.
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 drive unit ( page 18 ).
Autopilot Tuning > Rudder
Gains
(power boat only)
Low Speed Counter Allows you to set the rudder gain counter-correction for low speeds.
This setting applies to the vessel when operating below planing speed.
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 drive unit ( page 18 ).
Autopilot Tuning > Rudder
Gains
(power boat only)
High Speed Gain Allows you to set the rudder gain for high speeds.
This setting applies to the vessel when operating above planing speed.
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 drive unit ( page 18 ).
