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 ).
