The tilt mechanism is spring loaded. Due to the
variation in steering wheel offerings, the wheel
may spring up rapidly when depressing the re-
lease lever. ALWAYS KEEP ONE HAND ON
THE WHEEL DURING TILT ADJUSTMENT OR
INJURY MAY OCCUR.
C. Power Steering
Power steering is standard engine equipment on all Vista
models. It is comprised of an engine mounted pump,
hoses and steering cylinder. Power steering works in
conjunction with the helm and steering cable to move the
transom mount tiller arm and vertical drive more smoothly.
This is a “power assist” system and can greatly reduce
steering effort required. It is not, however, a full power
steering system as is used in automobiles. Some steer-
ing tension remains in the system.
On twin engine installations, only the starboard engine is
equipped with a power steering hydraulic assist pump.
Therefore, when operating on a single engine, it is im-
perative to operate with the starboard engine. If only the
port engine is used, hard steering will result.
NOTICE
DO NOT force the steering unit to either extreme.
This can place undue strain on the unit and can
lead to hydraulic line or seal failure.
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 diffi-
culty increase with time, it is possible additional bleeding
of the system is required. See your Four Winns dealer
for assistance. 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, steering will
be harder and more effort will be needed to steer the boat.
Check for a broken or loose belt on the power steering
pump. Also, low fluid levels in the power steering pump
reservoir will cause hard steering. If these items are not
the source of the problem, check for equipment or other
items lying on or up against the steering cable at the
D - 1 GENERAL
Four Winns boats are equipped with rotary-type steering
systems. Tilt and power steering are features which are
available on all Vista models.
A. Rotary Steering
In the rotary system, a rotary drum assembly is mounted
under the dash behind the steering wheel with a one piece
cable running through the boat into the engine compart-
ment. At the transom, the cable turns and is connected
to the engine.
B. Tilt Steering
If equipped with tilt steering, depress the release lever
with your thumb to tilt the steering wheel. See Figure D1.
Be sure to hold the top of the wheel to assist in position-
ing. Refer to the steering manufacturer’s literature for
additional information.
Figure D1: Tilt Steering Option
The tilt mechanism should not be adjusted when
the boat is moving. Sudden boat movement may
cause loss of balance resulting in loss of control
and/or injury.
