GENERAL SAFETY INFORMATION
ENOM00007-0
NOTICE: DANGER/WARNING/CAUTION/Note
Before installing, operating or otherwise handling your outboard motor, be sure to thoroughly read and understand this Owner’s Manual and carefully follow all of the instructions. Of particular importance is information preceded by the words “DANGER,”
“WARNING,” “CAUTION,” and “Note.” Always pay special attention to such information to
ensure safe operation of the outboard motor at all times.
ENOW00001-0
DANGER
Failure to observe will result in severe personal injury or death, and possibly property damage.
ENOW00002-0
WARNING
Failure to observe could result in severe personal injury or death, or property damage.
ENOW00003-0
CAUTION
Failure to observe could result in personal injury or property damage.
ENON00001-0
Note
This instruction provides special information to facilitate the use or maintenance of the outboard
motor or to clarify important points.
ENOM0008-0
EMERGENCY STOP SWITCH
The Emergency Stop Switch will stall the outboard motor when the stop switch tether is
pulled off. This stop switch tether can be attached to the operator of the outboard motor
to minimize or prevent injuries from the propeller in case the operator falls overboard.
We highly recommend use of the Emergency Stop Switch tether.
ENOW00004-0
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 inch.) stop
switch tether is coiled and can extended to a full 1300 mm (51 inch.).
GENERAL SAFETY INFORMATION 9
ENOM00009-0
SAFE OPERATION OF BOAT
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.
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.
ENOM00011-0
MAINTENANCE
As the owner of this outboard motor, you should be acquainted with correct maintenance
procedures. 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.
ENOM00012-0
MOUNTING
Outboard motor mounting must be performed by trained service person(s) using lift or
hoist with sufficient capacity.

boat
ENOW00006-0
WARNING
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
accordance with the instructions below.

Be sure that the anti ventilation plate of the
outboard motor is below the water surface
when running with the throttle wide open.
If the above condition cannot be met due
to the shape of the bottom of your boat,
please consult your authorized dealer.

CAUTION
z Before beginning the running test, check
that the boat with maximum capacity
loading floats on the water in a proper
attitude. Check the position of water
surface on the driveshaft housing. If the
water surface is near the bottom cowling, in high waves, water may enter the
engine cylinders.
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
opening of the bottom cowling during
cruising. Exposing the engine to such
conditions for extended periods can
lead to severe engine damage.

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
Nm (3.0 kgf) 13 ft-lb). Check the fasteners for tightness from time to time.
z Be sure to use outboard mounting fas-
teners included in the outboard motor
package or their equivalents in terms of
size, material, quality and strength.
Tighten fasteners to the specified torque
(30 Nm (3.0 kgf) 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.
