Step 6

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.
