power steering pumps
The power steering pumps supply pressurized fluid to the
SmartCylinders in order to steer the boat. The PCM controls a 12V
DC motor that drives a small gear pump. The pump assembly has
an integral fluid reservoir and pressure relief valves.
The steering pumps have an integral service valve that can be opened
to bypass the pumps and allow the engines to be manually repositioned.
They are used for service or in the case of an emergency.
Smartcylinders
The SmartCylinder is a hydraulic steering cylinder fitted with a
magnet and a position sensor. Each SmartCylinder can steer up
to two outboard engines.
remote-mounted steering service valves (optional)
When the service valves on the power steering pumps are not
easily accessible these optional remote-mounted valves can be
installed in a convenient location.
