HYDRAULIC STEERING
SYSTEM
________________
The steering system in your 453 Motor Yacht
is manufactured by Sea Star, a subsidiary of
Telefl ex (Canada, Ltd.), and is hydraulically as-
sisted. Hydraulic assisted steering is similar to
the power steering system in your automobile
and greatly reduces the manual effort necessary
to steer your yacht and maintain the desired
course. The Hydraulic Steering System in your
453 Motor Yacht differs from your automobile,
as a separate pump is not used to circulate the
hydraulic fl uid contained in the system; the
system is completely fi lled with hydraulic fl uid
and is free of air. As you turn your steering
wheel, the hydraulic fl uid is pumped by the
steering head into the appropriate fl uid line, Port
or Starboard, resulting in moving the steering
cylinder in the respective direction. The steering
cylinder is connected to the rudders and they
are subsequently turned, which enables your
yacht to turn in the desired direction; to Port or
Starboard. Access to the steering cylinder can
be obtained by removing the mattress of the bed
in the Aft Master Stateroom. (See photograph
below which illustrates the steering cylinder and
its connection to the rudders).
The Hydraulic Steering System in your 453
Motor Yacht utilizes an adjustable tilt-type
steering head, which allows you to adjust the
steering wheel angle for maximum personal
comfort. The steering head contains a vented
fi ll cap on single station models and on the
upper helm station ONLY on lower station
models. The vented cap is located on the top of
the steering head and forward of the steering
wheel. The lower station steering head fi ll cap
is NOT vented. The hydraulic fl uid level should
be checked on the upper helm station ONLY. If
needed, hydraulic fl uid is added at this location
to fi ll the reservoir to the proper level.
Maintenance of the Hydraulic Steering System
should only be performed by your Silverton
dealer or a qualifi ed technician, who is experi-
enced in marine hydraulic systems. Periodically
examine all connections and hydraulic lines for
any signs of leakage. If any leaks are noted, con-
tact your Silverton dealer for further inspection
and repair, if necessary.
