Hydraulic Steering Systems


Hydraulic Steering Systems

Raymarine Evolution pilots connect to hydraulic steering systems using a rugged hydraulic pump matched to the capacity of the hydraulic steering system.

If your system is hydraulic…
You’ll need to find out the size (in cc) of the hydraulic cylinder ram(s) mounted to the rudder or inboard engine boats, or to the drive unit on outboard engine boats. Your steering system documentation will have this information.

Autopilot Tip

If you cannot find the ram size on your steering system documentation, you can look on the cylinder ram itself for the brand and model number.

• In some systems with dual steering rams in parallel, cylinder capacity is the total of both rams. Rams in series only require single capacity valve. Hydraulic steering systems with steering rams over 500cc require our larger constant running pump used in conjunction with the relevant ACU.
