Set Rudder zero
This adjustment should be made in calm sea and side forces from
wind or current should be avoided.
• Bring the boat up to cruising speed, and head directly into the
wind.
• If the boat has twin engines, synchronize the engine RPM's.
• Set the trim tabs and stabilizers to have no effect on the boats
heading.
• Steer the boat manually on a steady course.
• Confirm the rudder ZERO position by rotating the course
knob clockwise.

Minimum rudder
Some vessels may have a tendency of not responding to small
rudder commands around the “course keeping” position because
of a small rudder, a rudder deadband or whirls/disturbance of the
water-stream passing the rudder.
By turning the Minimum Rudder function ‘On’, it may improve
the course keeping performance on some boats, but will increase
the rudder activity.
Turn the minimum rudder on
by turning the rotary course
knob.
Range: OFF-ON.
Default: OFF
Note ! Only set Minimum Rudder to ON if it proves to give a better
course keeping performance in calm sea.
