Steering Systems
G - 1
GENERAL
The steering system is operated through the
Electronic Vessel Control (EVC) system provides
a smooth and exact steering. It offers steering capa-
bilities which are not possible with traditional steering
systems. Consult engine operator’s manual for
specific information.
The helm steering unit sends an electrical signal via
the EVC system to the servo unit steering (SUS) on
the drive-unit.
Tilt Release Lever
The electronic steering is progressive and the turn
rate automatically adjusted to suit the actual boat
speed for optimized comfort and boat handling.
The wheel spins easier at low speeds, further
reducing driver effort.
Figure G1: Tilt Steering
For reliability the steering system is built with
redundancy on several levels.
The tilt mechanism should not be adjusted
when the boat is moving. Sudden boat move-
ment may cause loss of balance resulting in
loss of control and/or injury.
Full lock when driving at high speed will make
the boat turn strongly, which entails a great risk
of personal injury, and/or people aboard may
fall over or be thrown overboard. Warn every-
body aboard before doing any emergency
maneuvers.
The tilt mechanism is spring loaded. Due to the
variation in steering wheel offerings, the wheel
may spring up rapidly when depressing the
release lever. ALWAYS KEEP ONE HAND ON
THE WHEEL DURING TILT ADJUSTMENT
OR INJURY MAY OCCUR.
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 steering
manufacturer’s literature for additional information.
G - 2 STEERING LOAD
On boats with conventional drives, a load is placed
on the steering system by the propeller torque, and/or
water flowing past the outdrives. With the IPS the
propulsion forces and vibrations are absorbed by
the combined rubber suspension and sealing. The
propellers operate in undisturbed water with no
cavitation. Also an increased number of propeller
blades distribute the forces thereby reducing the effect
of the pulses created by the propellers on the hull.
All of this combined with the Electronic Vessel Control
(EVC) system provides a smooth and exact steering
with minimal to negligible steering load.
