In use, the SmartPump automatically adjusts its maximum hydraulic flow rate -- up to 2.4 litres per minute -- to suit the specific boat's steering cylinder size, and it's rated to work with cylinders from 4 to 24 cubic inches, delivering a lock-to-lock steering time of about 7 seconds on cylinders up to 17 cubic inches. It connects to the boat's hydraulic steering circuit via SAE ORB-5 ports (helm ports H1/H2, cylinder ports C1/C2, and a tank port T), and runs on a 10-30VDC supply protected by a 40A blade-type fuse, with a 9-foot (2.7m) power cable for routing to the boat's electrical panel. Physically it measures roughly 6.6 x 7.5 x 10.4 inches and weighs 16.5lb (7.5kg), built with an aluminium-alloy electronics housing (fully gasketed), a carbon-steel mounting bracket and an aluminium-alloy manifold and motor housing for a marine engine-room environment, rated to operate from -15C to 55C. It's typically installed alongside a Reactor 40 corepack and GHC 50 or compatible display, and is the hydraulic-steering counterpart to the steer-by-wire Reactor 40 corepack sold elsewhere in this catalog.
