Understanding the Rudder Angle in Relationship to the offset Distance
Because the drive unit is limited to a travel distance of 11.93 in. (303 mm) from fully retracted to fully extended (11.54 in. (293 mm) from end stop to end
stop in the example), the rudder angle of your boat is an important consideration when planning the connection of the drive unit to the tiller arm. For boats
with larger rudder angles, the drive unit must connect to the tiller arm closer to the rudder post so that the drive unit does not extend beyond the specified
distance limit.
NOTE: The maximum achievable torque on the rudder from the drive unit is lower on boats with larger rudder angles.
