Detailed Configuration Settings
Although all of the configuration is typically completed
automatically through wizards, you can manually adjust any
setting to fine-tune the autopilot.
Advanced configuration settings are available only when using
Dealer Mode (
settings are available during normal operation of the autopilot.
See the configuration section of the owner's manual provided
with the autopilot for more information.
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, before performing the

Autopilot Tuning Settings
To open the general autopilot tuning settings, select
Menu

>
Dealer Autopilot Configuration
.
Acceleration Limiter
: Allows you to limit the speed of autopilot-
controlled turns. You can increase the percentage to limit the
turn rate, and decrease the percentage to allow higher turn
rates.
Speed Source Settings
NOTE:
Speed source settings are available only for power
boats.
To open the speed source settings, select
Menu
>
Setup
>
Dealer Autopilot Configuration
>
Speed Source Setup
.
Speed Source
: Allows you to select the speed source.
Verify Tachometer
: Allows you to compare the RPM readings
on the helm control with the tachometers on the dashboard of
your boat.
Planing RPM
: Allows you to adjust the RPM reading on the
helm control at the point when your boat transitions from
displacement to planing speed. If the value does not match
the value on the helm control, you can adjust the value.
Planing Speed
: Allows you to adjust the planing speed of your
boat. If the value does not match the value on the helm
control, you can adjust the value.
Low RPM Limit
: Allows you to adjust the lowest RPM point of
your boat. If the value does not match the value on the helm
control, you can adjust the value.
High RPM Limit
: Allows you to adjust the highest RPM point of
your boat. If the value does not match the value on the helm
control, you can adjust the value.
Max. Speed
: Allows you to adjust the maximum speed of your
boat. If the value does not match the value on the helm
control, you can adjust the value.
Rudder Gain Settings
NOTE:
If you set these values too high or too low, the autopilot
may become overactive, attempting to constantly adjust the
heading at the slightest deviation. An overactive autopilot can
cause excess wear on the pump, and drain the battery at a
faster-than-normal rate.
To open the rudder gain settings, select

Rudder Gains
.
NOTE:
These settings apply only to sailboats, displacement-hull
powerboats, and powerboats with the speed source set to None.
Gain
: Allows you to adjust how tightly the rudder holds a
heading and makes turns.
Counter Gain
: Allows you to adjust how tightly the rudder
corrects turn overshoot. If you set this value too low, the
autopilot can overshoot a turn when attempting to counter the
original turn.
NOTE:
These settings apply only to planing-hull powerboats
with the speed source set to Tach - N2K or Proprietary or GPS.
Allows you to set the rudder gain for low speeds. This setting
applies to the vessel when operating below planing speed.
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.
High Speed
: Allows you to set the rudder gain for high speeds.
This setting applies to the vessel when operating above
planing speed.
High Speed Counter
: Allows you to set the rudder gain counter-
correction for high speeds. This setting applies to the vessel
when operating above planing speed.
Steering System Settings

Verify Steering Dir.
: Allows you to set the direction the rudder
must move to turn the vessel to port and to starboard. You
can test and reverse the steering direction if necessary.
Rudder Sensor Settings
NOTE:
Rudder sensor settings apply only when a rudder sensor
is connected to the autopilot system.
To open the rudder sensor settings, select
Menu

.
Max. Port Angle
: Allows you to enter the angle at which your
rudder turns furthest port.
Max. Starboard Angle
: Allows you to enter the angle at which
your rudder turns furthest starboard.
Calibrate Rudder Sensor
: Initiates a procedure that establishes
the maximum range of movement of the rudder and
calibrates the rudder-position sensor. If an error appears
during the calibration, the rudder-position sensor has likely
reached its limit. The sensor might not be correctly installed.
If the problem persists, you can bypass this error by moving
