42 SmartPilot X-5 Tiller & GP Tiller Installation & Setup Guide
• If the rudder gain is too low, the boat’s performance will be sluggish – it will take
a long time to make the 40° turn and there will be no overshoot (B).
Correct this understeer by increasing the rudder gain setting.
To adjust the rudder gain:
1. Access the
RUDD GAIN screen in Dealer calibration (see page 51 ).
2. Use
-1 or +1 to adjust the rudder gain.
3. Press and hold
standby for 2 seconds to save the changes.
4. Press
auto to check the SPX-5 Tiller system performance in Auto mode.
Counter rudder
Counter rudder is the amount of rudder the SPX-5 Tiller system applies to try to
prevent the boat from yawing off course. Higher counter rudder settings result in more
rudder being applied.
Checking
To check the counter rudder setting:
1. Set
RESPONSE to level 5 .
2. Motor your boat at cruising speed in clear water.
3. Press
auto to switch the SPX-5 Tiller 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. Access the
COUNT RUD screen in Dealer calibration.
2. Use the
-1 or +1 keys to adjust the counter rudder.
