GENERAL SAFETY INFORMATION
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 instruc-
tions. 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 1300 mm (51 inch.).
SAFE OPERATION OF BOAT
WARNING
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

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 MOV-
ING BOAT, GEAR HOUSING, PROPELLER, OR ANY SOLID DEVICE RIGIDLY ATTACHED TO
A BOAT OR GEAR HOUSING.
SERVICING, REPLACEMENT PARTS & LUBRICANTS

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.
INSTALLATION 13
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 tran-
som board holes before tightening the
bolts.
2 Be sure to tighten the mounting bolt nuts
to the specified torque.
(30Nm (13ft·lb) 3.0kgf)
(6.65in)
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
(30Nm (13ft·lb) 3.0kgf). Check the fasteners for tightness from time to time.
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
30Nm (13ft·lb) 3.0kgf). Test cruise to
check if fasteners are tightened
securely.
Outboard motor mounting must be per-
formed by trained service person(s)
using lift or hoist with sufficient capacity.

PRE-OPERATING PREPARATIONS 15
DANGER
CAUTION
PRE-OPERATING PREPARATIONS
1. Recommended gasoline types
Consult an authorized dealer for details on
handling of gasoline, if necessary.
Gasoline and its vapors are very flammable
and can be explosive.
When carrying a fuel tank containing gasoline:
Close the air vent screw of fuel tank cap,
or gasoline vapor will be emitted
through the air vent screw, creating a
fire hazard.
Do not smoke.
When or before refueling :
Stop the engine, and do not start the
engine during refueling.
Do not smoke.
Be careful not to overfill fuel tank. Wipe
up any spilled gasoline immediately.
When or before cleaning the gasoline tank :
Dismount fuel tank from the boat.
Place the fuel tank away from every
source of ignition, such as sparks or
open flames.
Do the work outdoors or in well venti-
lated area.
Wipe up any spilled gasoline immedi-
ately.
Use of low-quality gasoline results in a
short engine life as well as starting difficulties and other engine problems.
We recommend use for Fuel stabilizer.
Use of unleaded gasoline
Use a major brand of automotive unleaded
gasoline with a minimum posted octane
rating of 91RON. Automotive gasoline that
contain fuel injector cleaner are preferred
for added internal engine cleanliness.
Leaded gasoline is acceptable in areas
where unleaded gasoline is not available.
4
After cleaning gasoline tank :
Wipe up any spilled gasoline immedi-
ately.
If the fuel tank is disassembled for
cleaning, reassemble carefully. Imperfect assembly may cause a fuel leak,
possibly leading to fire or explosion.
Dispose of aged or contaminated gaso-
line in accordance with local regulations.
PRE-OPERATING PREPARATIONS16
CAUTION
WARNING
Use of alcohol free gasoline
Use of gasoline containing alcohol can
cause engine starting and/or operating difficulties, wear of and damages to engine
parts, and deterioration of chemical parts,
which may lead to shortening of your outboard motor’s life.
Note
The adverse effect caused by the alcohol
4
content is more severe with methanol than
with ethanol.
TOHATSU recommend the use of gasoline
if its ethanol content is less than 10% or
methanol content is less than 5%, only in
case alcohol free gasoline is not available.
The alcohol component of the gasoline
absorbs moisture from the air, which may
disturb regular fuel flow in the fuel system,
and also accelerate rusting of engine
parts.
Mixing of the moisture in the engine oil can
also deteriorate the properties of the lubricant.
If the use of gasoline containing alcohol is
inevitable, or presence of alcohol is sus-
pected in the gasoline, it is strongly 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 s
uch abnormality is
found, discontinue the use of such gaso-
line and contact our dealer immediately.
Damages resulting from the use of gasolines that contain alcohol are not covered
under the limited warranty.
Fuel tank capacity : 25 liters (6.6 U.S. gal)
Fuel Tank : When using a fixed fuel tank in
place of genuine fuel tank, it is recommended to select a one with a structure
facilitating interior cleaning.
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.
2. Recommended engine oil
CAUTION

PRE-OPERATING PREPARATIONS 17
Use a genuine engine oil or recommended
one (TCW3). Refer to your Distributor.
Will not recommend use of other two
stroke engine oil.
Do not mix different brands of oil.
Mixing different brands of oil, or different
types of oil even if the brand is the same,
may cause gelling, resulting in possible filter screen blockage. This could result in
serious engine damage because of
impaired lubrication performance.

If the recoil starter fails to operate
Remove the top cowl and the recoil
starter. Wrap a rope around the starter
pulley then pull quickly to start.
Use a 10 mm socket wrench as a rope
handle.

Be careful that your clothes or other items
do not get caught in the rotating engine
parts.
To prevent accident and injury, do not reattach the recoil starter after the engine
has been started using the emergency
starter rope. Be sure to put the top cowl
back on.
Immediately contact an authorized dealer
when reaching shore.
2. Warming up the engine
Warm the engine at low engine speeds for
about three minutes. This allows the lubricating oil to circulate to all parts of the
engine. Operating the engine without
warm up shortens the engine's life.
Be sure to check that cooling water is
coming out of the cooling water check
port during warm up.
If the engine is operated without water discharging from the check port or idle port,
the engine may over heat.
Be sure that no bystander(s) is within 2
meters from back of starting operator.
Do not operate the outboard motor with
top cowl removed from the power unit,
or contacting turning flywheel which can
lead to serious personal injury.
Be sure to stop engine immediately if cooling water check port is not discharging
water, and check if cooling water intake is
blocked. Operating engine could lead to
overheating potentially leading to engine
damage. Consult an authorized dealer if
the cause cannot be found.

3. Forward and reverse
Before shifting into forward or reverse,
make sure that boat is properly moored
and outboard motor can be steered fully to
the right and left. Make sure that no swimmer(s) is ahead or astern of the boat.
Attach other end of emergency stop
switch tether to the operator's clothing
or arm and keep it attached during
cruising.
Do not attach the tether to a part of
clothing that can be torn easily when
pulled.
Arrange the tether so that will not be
caught by any object when pulled.
Be careful not to pull the tether acciden-
tally during cruising.
Unintentional stop of engine can cause
loss of control of outboard motor. Rapid
loss of engine power can lead to falling
down or causing passenger(s) to be
thrown overboard.

ENGINE OPERATION 25
Be sure to warm up engine well before
starting cruise. Operating cold engine may
cause damage to your motor.
Note
Idle speed may be higher during warming
up of engine. If shifted to Forward or
Reverse during warming up, it may be difficult to shift back to neutral. In such case,
stop engine, shift to neutral, and restart
engine to warm up.
Note
Frequent shifting to forward or reverse can
accelerate wear or degradation of parts. In
such case, replace gear oil earlier than the
period specified.

5. Trim angle
The trim angle of the outboard motor can
be adjusted to suit the transom angle of
the hull, and load conditions. Choose an
appropriate trim angle that will allow the
anti ventilation plate to run parallel to the
water surface during operation.
Proper trim angle
The position of the thrust rod is correct if
the hull is horizontal during operation.
5
Improper trim angle
Set the thrust rod lower if the bow of the
boat rises above horizontal.
Do not put hand or finger in between
outboard motor body and clamp bracket
when adjusting trim angle to prevent
injury in case the outboard motor body
falls.
Unsuitable trim position can cause loss
of control of boat.
When testing a trim position, run boat
slow initially to see if it can be controlled
safely.
Improper trim angle
Set the thrust rod higher if the bow of the
boat is below horizontal.
Excessive trim up or down may lead to
unstable boat operation, potentially causing the steering difficulty that leads to accident during cruising.
Do not cruise at high speed if improper
trim position is suspected. Stop the boat
and readjust trim angle before continuing cruise.
