Constant Running Hydraulic Pump
When steering loads require a ram capacity of over 460cc (28cu in) the
constant running hydraulic pump provides the ideal autopilot drive system.
Hydraulic fluid is supplied from a self contained reservoir and flow to the
steering ram is controlled by integral solenoid operated valves.
Used with a solenoid operated bypass valve and a separate hydraulic ram,
this system is recommended for heavy duty applications on large
mechanically steered vessels.

Stern drive
The stern drive actuator must only be used on stern drives with cable
operated, power assisted steering.
The drive unit operates the power steering valve in exactly the same way
as the steering cable. A clutch disengages the drive unit to allow manual
steering when the autopilot is disengaged.
Installation kits are available for most popular types of steering manufac-
turers.
