Recommend 100R1 for power circuit, 5/16"ID hose or tube for manual circuit.
*If using 1/4"ID tube, runs should be shor t and SeaStar oil must be used.
System designed to use SeaStar oil (Mil spec H5606) or Dexron II (ATF)
if using 1250V or 1275V helms.

How it works:
SeaStar hydraulic power steering uses the ship’s engine(s) to provide
the “power” for the steering system, via an engine or electric motor
driven hydraulic pump.
A manual hydraulic steering system, consisting of a standard SeaStar
helm and a hydraulic steering cylinder, (fitted with an integral ser vo
cylinder and a power steering valve) supplies the “control” por tion of
the steering system.
Under normal conditions, with engines running, a hydraulic oil supply is
in a stand-by mode, ready to be directed to the steering cylinder as
dictated by the steering wheel, ser vo cylinder and power steering valve.
Turning the steering wheel left or right makes the system go from stand-
by into operating mode and move the steering cylinder accordingly.
In the event of a power source failure, hydraulic oil, from the steering
helm, is automatically diver ted directly into the ser vo and steering
cylinder, providing the helmsman with manual back-up steering.
An engine room mounted oil reser voir allows easy system fill and
assists the in-line oil cooler in cooling the hydraulic oil. An in-line oil filter
helps to protect the steering system components against contaminants.
• Effor tless steering from docking to top speed
• Responsive steering 3-1/2, turns lock to lock (or to suit)
• Automatic manual back up steering
• Simplified installation
• Multiple steering stations
