Raymarine Hydraulic Autopilot Pumps Raymarine Hydraulic Drive Pumps, designed to interface with Raymarine SmartPilots steering systems.

To match a Raymarine hydraulic pump to your vessel you need to learn the size (in cubic inches) of the actual hydraulic cylinder ram or rams that are mounted to the Rudder on inboard engine boats or the ram mounted to the drive on outboard engine boats. Your steering system documentation will have this information.

The Drive unit is the part that interfaces with your vessel’s steering system to keep you on the right course. Raymarine has a broad range of drive units to match almost any type of steering system.
