Raymarine hydraulic pump type 3-12 volt ART M 81122
Raymarine hydraulic steering systems The Evolution Raymarine are connected to the wheelhouse via a robust hydraulic pump suitable for the capacity of the wheelhouse itself.
If the wheelhouse is hydraulic ... You must know the volume (in cc) of the cylinder (s) mounted on the rudder shaft on boats with inboard engines or on outboard engines. You will find this information in the wheelhouse manual.
Advise If you do not find the volume of the cylinder in the wheelhouse manual, you can determine the make and model directly from the cylinder; you can then use our hydraulic cylinder ram cross-reference guide to determine which autopilot pump is compatible with your boat's hydraulic steering.
Cylinder volume: 350cc - 500cc
Peak pressure regulated at 12V: 80bar
Maximum flow rate (empty): 2000cc / min
