CLASS B COMPACT DRIVE UNIT
INSTALLATION INSTRUCTIONS
Important Safety Information
WARNING
See the Important Safety and Product Information guide in the autopilot product box for product warnings and
other important information.
You are responsible for the safe and prudent operation of your vessel. The autopilot is a tool that enhances your
capability to operate your boat. It does not relieve you of the responsibility of safely operating your boat. Avoid
navigational hazards and never leave the helm unattended.
To avoid possible personal injury and damage to your boat, the autopilot system should be installed by a
qualified marine installer. Specific knowledge of marine steering and electrical systems is required for proper
installation.
CAUTION
To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling,
cutting, or sanding.
When in use, beware of hot surfaces on the heat-sink, motor, and solenoid components to avoid possible
personal injury.
NOTICE
The drive unit movement must be limited by physical end stops. Failure to install end stops will cause the drive
unit to act as a travel limiter and will damage the drive unit.
When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vessel.
To obtain the best performance and to avoid damage to your boat, install this drive unit according to these
instructions. Professional installation of the drive unit is highly recommended, because specific knowledge of
rudder operation is required to properly install the drive unit. Read all installation instructions before proceeding
with the installation. If you experience difficulty during the installation, contact Garmin
