The hydraulic power steering ram ensures identical
positioning of the port and starboard rudders. Check
that rudder arms are tight and free of play. Ensure
that fluid reservoir is up to level and filter is clean.
The fluid reservoir and filter are located on the
starboard aft side of the engine room along with the
optional auto pilot pump. Sea Ray ® recommends
Sea Star hydraulic steering fluid or Dextron 3 auto
transmission fluid for the power steering system.
The hydraulic power steering system uses the
boat's engines to provide the "power" for the
steering system, via a mechanically driven
hydraulic pump.
A manual hydraulic steering system, consisting of
a helm and a hydraulic cylinder (fitted with an
integral servo cylinder and a power steering valve),
supplies the "control" portion of the steering system.
Under normal conditions, with engines running, a
hydraulic oil supply is in a standby mode, ready to
be directed to the steering cylinder as dictated by
the steering wheel, servo cylinder and power

steering valve. Turning the steering wheel left or
right makes the system go from "standby" 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 diverted into
the servo and steering cylinder, providing the
helmsman with manual backup steering.
An engine room mounted oil reservoir allows easy
fill and assists the in-line cooler in cooling the
hydraulic oil. An in-line oil filter helps to protect the
steering system components against contaminants.
