Chapter 4: SmartPilot X-5R Drive Settings
Counter rudder
Counter rudder is the amount of rudder the SPX-5R Drive system applies to try to
prevent the boat from oversteering. Higher counter rudder settings result in more
rudder being applied.
The default counter rudder gain is set during the initial seatrial AutoLearn process
(see page 40).

COUNT RUD
Rudder damping
If the SPX-5R Drive system 'hunts' when trying to position the rudder, adjust the
rudder damping value to minimize this. Increasing the rudder damping value reduces
hunting. Increase the damping one level at a time until the autopilot stops hunting, and
always use the lowest acceptable value

AutoTrim
The AutoTrim setting determines the rate at which the SPX-5R Drive system applies
'standing helm' to correct for trim changes.
The default AutoTrim is set as part of the AutoLearn process (see page 40).
If you need to change the setting, increase the AutoTrim one level at a time and use
the lowest acceptable value:
•
If the SPX-5R Drive system gives unstable course keeping or excessive drive
activity, decrease the AutoTrim level.
•
If the SPX-5R Drive system takes too long to settle onto a new course, increase
the AutoTrim level
•
If the AutoTrim level is too high, the boat will be less stable and snake around the
desired course

Response level
This sets the default SPX-5R Drive system response level setting. The response level
controls the relationship between course keeping accuracy and the amount of helm/
drive activity. You can make temporary changes to response during normal operation
(see your Operating Guide for details).
