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.
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.
Failure to observe will result in severe personal injury or death, and possibly property damage.
!
Note
This instruction provides special information to facilitate the use or maintenance of the
outboard motor or to clarify important points.
Failure to observe could result in personal injury or property damage.
!
!
Failure to observe could result in severe personal injury or death, or property damage.
GENERAL SAFETY INFORMATION
!
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 1,300 mm (51 inch.).

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.
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.
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.
MOUNTING
Outboard motor mounting must be performed by trained service person(s) using lift or
hoist with sufficient capacity.
!
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.

When installing two outboard
engines, be sure to keep an interval
of approximately 580 mm (22.8 in)
between the two.
Transom matching
1 Be sure that the anti ventilation plate
of the outboard motor is 30-50mm
(1.2-2 in) below the bottom of hull.
If the above condition cannot be
met due to the shape of the bottom
of your boat, please consult your
authorized dealer.
2 To attach the outboard motor to the
boat, tighten the clamp screws by
turning their handles.
Also, use the bolts to secure
the outboard motor brackets on
transom board.
Secure the outboard motor with a
rope to prevent loss overboard.

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.

• 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.
• 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.

Mounting bolts should be installed with
the bolt head at inside surface of the
transom. Mounting bolts installed with
the threaded end at the inside surface of
the transom can cause personal injury.

Notes
1. Apply sealing agent, such as
silicone sealed between the bolts
and the transom board holes before
tightening the bolts.
2. Be sure to tighten the mounting bolt
nuts to the specified torque.

• Mounting the outboard motor without
following this manual can lead to
unsafe conditions such as poor
maneuverability, lack of control or fire.
• 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 (3.0kgf) 13ft·lb).
Check the fasteners for tightness from
time to time.
• Be sure to use outboard mounting
fasteners 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 (3.0kgf) 13ft·lb).
Test cruise to check if fasteners
are tightened securely.
• Outboard motor mounting must
be performed by trained service
person(s) using lift or hoist with
sufficient capacity.
