GENERAL SAFETY INFORMATION
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
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
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 lanyard is coiled and can extended to a full 1300 mm (51 inch.).
ENOM00800-A
PERSONAL FLOATATION DEVICE
As the operator/driver and passenger of the boat, you are responsible to wear a PFD (Personal Floatation Device) while on the boat.

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 61). 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.
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.

INSTALLATION
ENOM00024-A
ENOW00006-B
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.
ENOW00006-0
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.
ENOW00009-0
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 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 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-

FUEL RATING
TOHATSU engines will operate satisfactorily when using a major brand of unleaded
gasoline meeting the following specifications:
USA and Canada — having a posted
pump Octane Rating of 87 (R+M)/2 minimum. Premium gasoline (92 [R+M]/2
Octane) is also acceptable. Do not use
leaded gasoline.
Outside USA and Canada — Use
unleaded gasoline with declared octane
rating of 91 RON or over. Use of premium
gasoline of 98 RON is also allowed.
ENOM00032-A
GASOLINES CONTAINING
ALCOHOL
The fuel system components on your
TOHATSU engine will withstand up to 10%
ethyl alcohol (hererinafter referred to as the
"ethanol"), content in the gasoline. But if
the gasoline in your area contains ethanol,
you should be aware of certain adverse
effects that can occur. Increasing the percentage of ethanol in the fuel can also
worsen these adverse effects. Some of
these adverse effects are caused because
the ethanol in the gasoline can absorb
moisture from the air, resulting in a separation of the water/ethanol from the gasoline
in the fuel tank.
These may cause increased:
z Corrosion of metal parts
z Deterioration of rubber or plastic parts
z Fuel permeation through rubber fuel
lines
z Starting and operating difficulties
If the use of gasoline containing alcohol is
inevitable, or presence of alcohol is suspected in the gasoline, it is recommended
to add a filter that has water separating
capability, and check the fuel system for
leaks and mechanical parts for corrosion
and abnormal wear more frequently.
And, in case any of such abnormality is
found, discontinue the use of such gasoline and contact our dealer immediately.
If the outboard motor will only be used
infrequently, please see the remarks on
fuel deterioration in the STORAGE chapter
(P 78) for additional information.
ENOW00020-0
When operating a TOHATSU engine on
gasoline containing alcohol, storage of
gasoline in the fuel tank for long periods
should be avoided. Long periods of storage, common to boats, create unique problems. In cars, alcohol blend fuels normally
are consumed before they can absorb
enough moisture to cause trouble, but
boats often sit idle long enough for phase
separation to take place. In addition, internal corrosion may take place during stor-

Fuel leakage can cause fire or explosion,
potentially leading to severe injury or loss
of life. Every fuel system part should be
checked periodically, and especially after
long term storage, for fuel leak, change of
hardness of rubber, expansion and/or corrosion of metals. In case any indication of
fuel leakage or degradation of fuel part is
found, replace relevant part immediately
before continuing operation.
ENOW00019-0
Do not fill the fuel tank over capacity. The
rise of gasoline temperature may cause
gasoline to expand which, if overfilled, may
leak through air vent screw when it is open.
Leaking gasoline is a dangerous fire hazard.
ENOM00043-B

Consult an authorized dealer for details on
handling gasoline, if necessary.
Gasoline and its vapors are very flammable
and can be explosive.
When carrying a fuel tank containing gasoline:
z Close the fuel tank cap and air vent
screw of fuel tank cap, or gasoline vapor
will be emitted through the air vent
screw, creating a fire hazard.
z Do not smoke.
When or before refueling:
z Be sure to remove the static electricity
charged in your body before refueling.
z The sparks due to static electricity may
cause explosion of flammable gasoline.
z Stop the engine, and do not start the
engine during refueling.
z Do not smoke.
z Be careful not to overfill fuel tank. Wipe
up any spilled gasoline immediately.
When or before cleaning the gasoline tank:
z Dismount fuel tank from the boat.
z Place the fuel tank away from every
source of ignition, such as sparks or
open flames.
z Do the work outdoors or in a well venti-
lated area.
z Wipe off gasoline well immediately if
spilled.
z
After cleaning gasoline tank:
z Wipe off gasoline well immediately if
spilled.
z If the fuel tank is disassembled for
cleaning, reassemble carefully. Imperfect assembly may cause a fuel leak,
possibly leading to fire or explosion.
z Dispose aged or contaminated gasoline
in accordance with local regulations.
