DISADVANTAGES: Inadvertent activation
oi the switch is also a possibility. This
could cause any or all of the following
potentially hazardous situations:
a Loss of balance and falling forward of
unstable boat passengers
- a particular
concern in bow rider type boats.
a Loss of power and directional control in
heavy seas, strong current or high winds.
Loss of control when docking.
As we cannot possibly know of and advise
the boating public of ALL conceivable
boatlmotor types and/or poor operating
practices, the final decision of whether or
r~ot to use a LANYARD STOP SWITCH
rests with you, the
owner/driver.
We strongly recommend that other occu -
pants be instructed on proper starting and
operating procedures should they be re
-
quired to operate the outboard and boat in
an emergency.
WARNING
It is difficult for a person standing or float -
ing in the water to move clear if they see a
powerboat heading toward them, even at
slow speed. Shift the unit to neutral and
shut off engine when your boat is near
people in the water.
SERIOUS INJURY IS LIKELY IF A PER
-
SON IN THE WATER IS STRUCK BY A
MOVING BOAT, GEAR HOUSING, PRO
-
PELLER, OR ACCESSORY RIGIDLY AT -
TACHED TO YOUR BOAT OR OUT -
BOARD.
AWARNING
The use of accessories not manufactured
or sold by Mercury Marine is not
recom-
mendedfor use with your outboard. If your
outboard or outboard operating system is
equipped with an accessory not manufac
-
tured by Mercury Marine, be sure to read
the Operation and Maintenance Manual for
that accessory before operation. If you
haven't been supplied with such a manual,
contact your dealer or the manufacturer of
the accessory to secure the applicable
manual.
AWARNING
USE CARE when transporting fuel con -
tainer, whether in a boat or car. DO NOT fill
fuel container to maximum capacity. Gaso
-
line will expand considerably as it warms
up and can build up pressure in the fuel
container. This can cause fuel leakage and
a potential fire hazard.
