Ensuring correct alignment
CAUTION:
Take care to ensure correct rudder sensor alignment. If the
sensor is not correctly aligned, the autopilot system will not
perform accurately.
Vertical alignment
When viewed from the front of the boat, the connecting rod should:
• be as level as possible, so the ball-joints at each end are level
• remain parallel to the tiller arm’s plane of rotation at all times
Note: If misalignment exceeds +/-5° the ball-joints will bind or fail.
