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 (Enabling Dealer Configuration). User-specific
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
autotune procedure (Performing the Autotune Procedure).
Autopilot Tuning Settings
To open the general autopilot tuning settings, select Menu >
Setup > Dealer Autopilot Setup.
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 Setup > 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.
