Raymarine Type 1 Hydraulic Pump 12V
Part #: M81120
Raymarine Evolution pilots connect to hydraulic steering systems using a rugged hydraulic pump matched to the capacity of the hydraulic steering system.

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.

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. Once you have the number use our hydraulic cylinder ram cross-reference guide to determine which hydraulic autopilot pump is compatible with your vessel's hydraulic steering system.

Notes:
- 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 - contact Raymarine for details.
- An authorised Raymarine dealer is best suited to installing a hydraulic autopilot system.
- Type 0.5 suitable for Volvo D4/D6 Sterndrive applications.
