Setting Slow Speed Rudder Response
It is best to set the s
low speed Rudder
Response first. These adjustments are much
easier to do if the water is calm and there is
little wind.
At this point, you will have finished adjusting
your compass and exited the Set-up Routine.
Move your boat to an open area of water
away from docks and other boats.
Your vessel may make several turns while
you are setting the Rudder Response. Make
sure that you and your passengers are
braced for unexpected movement.
Adjust your throttle so that your boat is
moving at a commonly used slow speed. If
you fish often, this could be your trolling
speed. Bring your boat onto a course.
Turn ON the SP-70 or SP-80 Autopilot. To
turn on the Autopilot, press the Pilot Key.
The Autopilot will fist display SP, then the
software version number. Finally, the present
course followed by a capital letter “P” will be
displayed. [xxxP]. The Autopilot will now
begin to steer the boat along the displayed
course. The autopilot is in PILOT MODE and
is steering by the compass.
OFF
If you wish to turn off the Autopilot, press and
hold the sby/Off Key for 2 seconds.
Immediately after pressing this key, you will
have manual vessel steering control.
With the Autopilot on, press the Set Key. For
a five second interval the display will read
either [FASt] (fast) or [SLOU] (slow). This is
the Rudder Response speed setting that your
Autopilot is currently using.
If the display is reading [FASt], press the
Green Key during the five second interval to
change the display to [SLOU]. Your vessel is
now using the slow boat speed Rudder
Response settings.
Allow the Autopilot to steer your boat for
a few minutes, so you can measure its
performance. The pilot may move back
and forth across the desired course line.
This movement occurs when your rudder
sensitivity is too high or your counter rudder
sensitivity is set too low. The autopilot is
over-correcting for course errors (refer to
diagram on page 65).
To decrease the Rudder sensitivity:
Press the Set Key. The display will show
[SLOU] for five seconds. During this five
second interval, press the Set Key again and
the Autopilot will display the Rudder
sensitivity setting.
Press the Red Key once to decrease the
sensitivity setting by one step.
