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.
