GENERAL SAFETY INFORMATION
ENOM00009-0
SAFE OPERATION OF BOAT
1
As the operator/driver of the boat, you are responsible for the safety of those aboard
and those in other boat around yours, and for following local boating regulations. You
should be thoroughly knowledgeable on how to correctly operate the boat, outboard
motor, and accessories. To learn about the correct operation and maintenance of the
outboard motor, please read through this manual carefully.
It is very difficult for a person standing or floating in the water to take evasive action
should he or she see a power boat heading in his/her direction, even at a slow speed.
Therefore, when your boat is in the immediate vicinity of people in the water, the
outboard motor should be shifted to neutral and shut off.
ENOW00005-0
WARNING
SERIOUS INJURY IS LIKELY IF A PERSON IN THE WATER MAKES CONTACT WITH A MOVING
BOAT, GEAR HOUSING, PROPELLER, OR ANY SOLID DEVICE RIGIDLY ATTACHED TO A BOAT OR
GEAR HOUSING.
ENOM0008-A
EMERGENCY STOP SWITCH
The Emergency Stop Switch will stall the outboard motor when the stop switch lanyard is pulled off. This stop switch lanyard has to be attached to the operator of the
outboard motor to minimize or prevent injuries from the propeller in case the operator falls overboard.
It is operator’s responsibility to use the Emergency Stop Switch Lanyard.
ENOW00004-A
WARNING
Accidental activation of the Emergency Stop Switch (such as the tether being pulled out in
heavy seas) could cause passengers to lose their balance and even fall overboard, or it could
result in loss of power in heavy seas, strong currents, or high winds. Loss of control while
mooring is another potential hazard.
To minimize accidental activation of the Emergency Stop Switch, the 500 mm (20 in.) stop
switch lanyard is coiled and can extended to a full 1300 mm (51 in.).
ENOM00800- A
PERSONAL FLOATATION DEVICE
As the operator/driver and passenger of the boat, you are responsible to wear a PFD
(Personal Flotation Device) while on the boat.
GENERAL SAFETY INFORMATION 11
ENOM00010-0
SERVICING, REPLACEMENT PARTS & LUBRICANTS
We recommend that only an authorized service shop perform service or maintenance
on this outboard motor. Be sure to use genuine parts, genuine lubricants, or recommended lubricants.
ENOM00011-A
MAINTENANCE
As the owner of this outboard motor, you should be acquainted with correct maintenance procedures following maintenance section of this manual (See page 60). It is
the operator's responsibility to perform all safety checks and to ensure that all lubrication and maintenance instructions are complied with for safe operation. Please
comply with all instructions concerning lubrication and maintenance. You should take
the engine to an authorized dealer or service shop for periodic inspection at the prescribed intervals.
Correct periodic maintenance and proper care of this outboard motor will reduce
the chance of problems and limit overall operating expenses.
Carbon Monoxide Poisoning Hazard
Exhaust gas contains carbon monoxide, a colorless and odorless gas which can be
fatal if inhaled for any length of time.
Never start or operate the engine indoors or in any space which is not well ventilated.
1
Gasoline
Gasoline and its vapors are very flammable and can be explosive. Use extreme care
when handling gasoline. You should be thoroughly knowledgeable on how to correctly
handle gasoline by reading this manual.

1. Mounting the outboard
motor on boat
ENOW00006-B
WARNING
Before installing the outboard motor on the
boat, hang the outboard motor with the
hoist or equivalent device by attaching the
engine hanger to the outboard. Use the hoist
with allowable load is 150 kg (330 lbs) or
above.
ENOW00009-0
WARNING
z Mounting the outboard motor without
following this manual can lead to unsafe
conditions such as poor maneuverability,
lack of control or fire.
z Loose clamp screws and/or mounting
bolts can lead to the release or displacement of the outboard motor, possibly
resulting in lost of control and/or serious
personal injury. Be sure that fasteners are
tightened to the specified torque (30 N·m
(3.0 kgf·m) 13 ft·lb). Check the fasteners
for tightness from time to time.
z Be sure to use outboard mounting fasten-
ers included in the outboard motor package or their equivalents in terms of size,
material, quality and strength. Tighten
fasteners to the specified torque (30 N·m
(3.0 kgf·m) 13 ft·lb). Test cruise to check
if fasteners are tightened securely.
z Outboard motor mounting must be per-
formed by trained service person(s) using
lift or hoist with sufficient capacity.
Outboard motor mounting must be performed by trained service person(s)

Most boats are rated and certified in terms
of their maximum allowable horsepower, as
shown on the boat’s certification plate. Do
not equip your boat with an outboard motor
that exceeds this limit. If in doubt, contact
your dealer.
Do not operate the outboard motor until it
has been securely mounted on the boat in

z Incorrect outboard motor mounting
height or existence of underwater
object(s), such as hull bottom design,
bottom surface conditions or underwater accessories, can cause water spray
possibly reaching the engine through an

CAUTION
Be careful not to loop the remote control

less. Otherwise, it affects the service life of
the cable.

Measure the distance from the remote
control box to the outboard motor
where the remote control cable should
be routed.
Prepare a cable that is 300-450mm
(11.8-17.7in) longer than the measured
distance.
Temporarily pull the cable along the
intended cable route to check its length
is sufficient.
Connect the remote control cable to the
engine, then run the cable to the remote
control box, making sure it is not sharply
bent, too taut and free from obstructions that could interfere with steering.
