Raymarine 12V Hydraulic Pump Drive Unit, Type 2

For use with hydraulic steering systems. 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 engine boats, or to the drive unit on outboard engine boats. Your steering system documentation will have this information. Must match to the capacity of steering cylinder ram in cc's.
