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.

Failure to observe will result in severe personal injury or death, and possibly property damage.

Failure to observe could result in severe personal injury or death, or property damage.

Failure to observe could result in personal injury or property damage.

Note

This instruction provides special information to facilitate the use or maintenance of the
outboard motor or to clarify important points.

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.

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.

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.

SERVICING, REPLACEMENT PARTS & LUBRICANTS

We re commend th at on ly an authori zed ser vice sho p per f orm se rvice 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.

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.

Position ... Above keel line

Set engine at center of boat.

Transom matching

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.

MF, EF, EP type

To attach the outboard motor to the

①

boat, tighten the clamp screws by
turning their handles.
Al so, tighten the bolts. S e cure
the outboard motor with a rope to
prevent loss overboard.

Note

A rope is not included in the standard
accessories.

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 engine to such conditions
for extended periods can lead to
severe engine damage.

Notes

1. Apply sealing agent such as
silicone sealed between the bolts
and transom board holes before
tightening the bolts.

2. Be sure to tighten mounting bolt
nuts to the specified torque. (30

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
torque (30 Nm (3.0kgf)13ft·lb). Test
cruise to check if fasteners are
tightened securely.
