Adjusting
To adjust the rudder gain:
1. Enter Dealer calibration as described on
page 7
.
2. Use
disp
as necessary to access the
RUDD GAIN
screen (see
page 30
).
3. Use the
-1
or
+1
keys or the
rotary control
to adjust the rudder gain.
4. Hold down
standby
for 2 seconds to save the changes and leave Dealer
calibration.
5. Press
auto
to check SPX system performance in Auto mode.
Counter rudder
Counter rudder is the amount of rudder the SPX system applies to try to prevent the
boat oversteering. Higher counter rudder settings result in more rudder being applied.
Checking
To check the counter rudder setting
1. Ensure you have set the response to level
5
, as described above.
2. Motor your boat at cruising speed in clear water.
3. Press
auto
to switch the SPX system to Auto mode, then make a 90° course
change:
• When gain and counter rudder are both set correctly, the boat performs a
smooth continuous turn with minimal overshoot.
• If the counter rudder is too low, the boat will still overshoot.
• If counter rudder is too high, the boat will ‘fight the turn’ and make a series of
short, sharp turns: this results in a very ‘mechanical’ feel as the boat changes
course.
Adjusting
To adjust the counter rudder:
1. Enter Dealer calibration as described on
page 7
.
2. Use
disp
as necessary to access the
COUNT RUD
screen (see
page 30
).
