Checking SPX-5 Wheel system operation

Before manually adjusting any settings, familiarize yourself with basic SPX-5 Wheel
system operation, as follows:
1. Steer onto a compass heading and hold the course steady at a normal cruising
speed. If necessary, steer the boat manually for a short time to check how the boat
steers.
2. Press auto to lock onto the current heading. The SPX-5 Wheel system should
hold the locked heading in calm sea conditions.
3. Use -1, +1, -10 and +10 and observe how the SPX-5 Wheel system alters the
course to port and starboard.
4. Press standby to return to manual steering.
If you feel you need to fine tune the SPX-5 Wheel system performance, you can do so
by using one or more of the procedures below to adjust:
•

Response level.

• Rudder gain.
• Counter rudder
• AutoTrim.
Over time you may wish to repeat these adjustments using a range of sea conditions
and headings to achieve optimum all-round performance for your particular vessel
and preferences.
Adjust these settings when motoring your boat at cruising speed.
Response level
The principal method of adjusting the performance of an SPX-5 Wheel system is by
changing the response level. This controls the relationship between the SPX-5 Wheel
system's course keeping accuracy and the amount of helm/drive activity.

This setting gives good course keeping with crisp, well controlled turns
under normal operating conditions.
This setting provides the tightest possible course keeping and greatest
rudder activity. This can lead to a rough passage in open waters as the
