Before you can test the system, make sure following things are correct:

Connect the electronics. Make absolutely sure the autopilot is set to “reversible drive” or equivalent. Don’t use
settings like “solenoid” or “hydraulic drive” as these settings will disable the speed control of the autopilot leaving
the drive running at 100% speed or 0%, but nothing in between. Make sure the clutch voltage is set to the
correct voltage. Some brands have a default clutch voltage that has to be changed. B&G uses 9 volts as
standard, Raymarine uses 12 volts, both even on 24 volts input. This should be adjusted to the correct voltage
to guarantee a proper working of the clutch. The B&G and Raymarine course computer has to be opened for dip
switches to be changed. The Simrad pilot can be adjusted via software in the setup menu on the screen. Always

With the clutch under power, connect power for a short time to the motor cables. The system should get in

The direct drive is “greased for life”, so should no be opened. No maintenance is required except for periodic
checks of all bolted connections. As the rudder system, the steering system and the autopilot drive is exposed
to heavy vibrations (mainly by cruising on motor), all bolted connections should be yearly checked. The only
parts that could wear in time are the balls of
