Horizontal alignment
When viewed from above (as shown in the illustration above):
• the sensor arm must be between 75 mm (3 in) and 310 mm (12 in)
from the tiller arm
• with the rudder amidships, the sensor arm should be at 90° to the
connecting rod and directly opposite the cable entry point on the
sensor body
• when the rudder moves from hardover to hardover:
• the sensor arm and the tiller arm must remain parallel to each
other at all times
• sensor arm movement must not exceed +/- 60°: if the steering
system drives the sensor arm beyond these limits it will
damage the rudder position sensor
