Raymarine Hydraulic Steering Systems.

Raymarine SmartPilots 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 engined boats or to the drive unit on outboard engined boats. Your steering system documentation will have this information.

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 Raymarine's larger constant running pump used in conjunction with SPX and SPX-SOL course computers.

An authorised Raymarine dealer is best suited to installing a hydraulic autopilot system.
