Install the Drive Unit
Raymarine produces a wide range of drive units to suit different types
of steering systems:
• The rotary drive is designed for steering systems that can be
driven from the helm position through a chain and sprockets.
• The linear and hydraulic linear drives are designed for boats
with existing mechanical steering systems, and drive the rudder
directly. The hydraulic linear drive is suitable for larger boats and
heavier duty steering applications.
• The hydraulic pump and constant running hydraulic pump
(CR pump) are primarily designed for boats with existing
hydraulic steering systems. Alternatively, you can use them in
combination with a secondary steering ram on boats with
mechanical steering. The CR pump is suitable for larger boats and
heavier duty steering applications.
• The I/O drive (the Inboard/Outboard or stern drive) is designed
to drive cable operated, power assisted outboard steering systems.
To control a Raymarine drive or pump, connect it to the motor
terminals on the course computer (and clutch terminals where
necessary). For Raymarine CR pumps, connect the solenoids to the
motor and solenoid terminals on the course computer.
