GENERAL
The stern drive V series models are equipped with
rotary-type steering systems. Inboard models are
equipped with hydraulic steering. Certain V series may
be equipped with an Electronic Vessel Control (EVC)
system. Tilt and power steering are also avail able.
Consult engine operator's manual and manufacturer's
literature for further information regarding your particu-
lar steering system.
A. Rotary Steering
In the rotary system, a rotary drum assem bly 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 tran som, the cable
turns and is connected to the drive tiller and the power
steering unit. See Figure G1.
Figure G1: Back of Helm Console
B. Power Steering - Stern Drive
Power steer ing is available on certain V series
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 mounted tiller arm
and vertical drive more easily.
This is a "power assist" system and can greatly reduce
steering effort required. It is not, howev er, a full power
steering system as is used in automobiles. Some
steering tension remains in the system. Restricting
move ment of the steering cable will limit or stop the
steering system's hydraulic assist.
Steering Systems - Section G
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.
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
Rotary Steering
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 i ng 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 equipment 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.
Steering Systems
NOTICE
DO NOT interfere with or restrict steering cable
movement through the last 90
engine. DO NOT use cable retainers, clamps or
tie straps. Using one or all of these could
restrict the cable movement near the engine.
DO NOT tie wiring harnesses or other control
cables to the steering cable. Make sure the
deck coaming pads and bulkheads allow for
steering cable movement in all positions of trim.
NOTICE
When storing equipment in the engine com part-
ment, be sure to avoid contact with the steering
cable. Cables may become kinked or damaged
and may increase steering effort.
After the first two hours of running time, check
the entire steering system for loose bolts, nuts
and fasteners which could adversely affect
steering control.
