Mechanical steering systems
If you are fitting the pump to a boat with mechanical steering you will need to
connect it to a secondary steering ram, along with a solenoid-operated bypass
valve. This bypass valve allows you to switch between autopilot course control
and manual steering.
To fit to a mechanical steering system:
Use suitable hydraulic pipes to connect the pump to the secondary steering
ram and a suitable reservoir.
Install the solenoid-operated bypass valve (part number: M81167) across
these pipes (as shown in Figure 10).
Connect the bypass valve to the CLUTCH terminals on the course computer
or ACU using at least 1.5 mm
Note:
Follow the manufacturer's instructions for mounting the hydraulic ram and reservoir.
