Steering Systems - Four winns 338 Vista Owner's Manual

G - 1 GENERAL
The stern drive Vista models are equipped with
®
rotary-type steering systems. A tilt steering wheel is
standard on the 338 Vista
A. Tilt Steering
The steering wheel can be tilted up or down so as to
enhance the driver's comfort and enjoyment. To tilt the
steering wheel, depress the release lever with your
thumb. See Figure G1. Be sure to hold the top of the
wheel to assist in positioning. Refer to the steer ing
manufactur er's literature for additional informa tion.
Figure G1: Tilt Steering
The tilt mec ha nism should not be ad just ed
when the boat is mov ing. Sud den boat mov e-
ment may cause loss of balance resulting in
loss of control and/or injury.
The tilt mec ha nism is spring load ed. Due to the
vari ation in stee ring wheel of fer ings, the wheel
may spring up rap idly when de pre ss ing the
re lea se le ver. AL WA YS KEEP ONE HAND ON

B. Rotary Steering
In the rotary system, a rotary drum assem bly is
mounted under the dash behind the steering wheel.
A one piece cable runs from the drum assembly
through the boat into the engine compart ment.
At the tran som, the cable turns and is connected
to the drive tiller and the power steering unit.
C. Power Steering
Power steer ing is standard engine equipment on
stern drive Vista models. It is comprised of an engine
®
mounted pump, control valve, hoses, and steering
cylin der. Power steering works in conjunc tion with the
helm and steering cable to move the transom mount-
ed tiller arm and vertical drive more easily.
On twin engine installations, only the starboard engine
is equipped with a power steering hydraulic assist unit.
Therefore, when operating on a single engine, it is
imperative to operate with the star board engine. If only
the port engine is used, hard steering will result.
NOTICE
DO NOT force the s teer ing wheel to ei ther
ex treme position. This can place undue strain
on the unit and can lead to power steering
damage.
Upon commissioning the boat, it is necessary to
purge the system of air. This is performed by your
Four Winns dealer during pre-delivery service.
Should steering difficulty increase with time, it is
possible additional bleeding of the system is required.
See your Four Winns dealer for assis tance. This and
other adjustments on power steering units are critical
and should be performed only by a qualified service
technician.
If the power steering becomes inoperative, steer ing
will be harder and more effort will be needed to steer
the boat. Check for a broken or loose belt on the
power steer ing pump. Also, low fluid levels in the
power steer ing pump reser voir will cause hard steer-
ing. If these items are not the source of the problem,
check for equip-ment or other items lying on or up
against the steering cable at the back of the boat.
The cable must be free and clear to slide back and
forth. Any item blocking free movement of the cable
will result in harder steering and possible damage to
the steer ing cable. If unable to locate or correct the
problem, have the steering cable in spected and
lubri cated by your Four Winns dealer.
