GENERAL SAFETY INFORMATION

WARNING

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

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 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 comm end t hat o nly an a uthorized serv ice 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’

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.

Secure the outboard motor with a
rope to prevent loss overboard.

Note

A rope is not included in the standard

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.

Installing the remote control devices

!

When using other than Tohatsu's genuine
remote control box, DO NOT select the
one without neutral safety switch that
prevents in-gear start.
Use of remote control box without neutral
safety switch can allow start of engine with
gear at other than neutral shift, potentially
leading passengers to falling or causing
passenger to be thrown overboard.

It is recommended that you consult

3. Installing the battery

Place the battery box in a convenient

position away from possible water
spray. Securely fasten both the box
and the battery so they do not shake
loose.

Note

Minimum recommended battery : 12V,
70AH (465 Marine Cranking Amps
(MCA) or 350 Cold Cranking Amps
(CCA)) Specifications and features of
batteries vary among the manufacturers.
Consult the manufacturer for details.

loss of sight. Use safety glasses and
rubber gloves.

In case battery electrolyte comes in
contact with:

Skin, flush thoroughly with water.

DANGER

21

!

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:

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 a well ventilated

●

area.
Wipe off gasoline well immediately if spilt.

●

After cleaning gasoline tank:

Wipe off gasoline well immediately if spilt.

●

If the fuel tank is disassembled for cleaning,

●

reassemble carefully. Imperfect assembly
may cause a fuel leak, possibly leading to
fire or explosion.
Dispose aged or contaminated gasoline in

●

accordance with local regulations.

Recommended gasoline types

!

Use of low-quality gasoline results in a short
engine life as well as star ting difficulties and
other engine problems.
We recommend use for Fuel stabilizer.

Use of unleaded gasoline

UNITED STATES AND CANADA:

Use a major brand of automotive unleaded
gasoline with a minimum posted octane
rating of 87. Mid-grade automotive gasoline
that contain fuel injector cleaner are preferred
for added internal engine cleanliness. Leaded
gasoline is not recommended.

INTERNATIONAL :

of automotive unleaded gasoline with a
minimum posted octane rating of 91RON.
Automotive gasoline that contain fuel injector
cleaner are preferred for added internal
engin e cle anlines s. Le aded gasoline is
acceptable in areas where unleaded gasoline
is not available.

Use a major brand

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 par ts, which may
lead to shortening of your outboard motor’s
life.

Note

The adverse effect caused by the alcohol 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.
Th e alcohol comp onen t of the gas oline
absorbs moisture from the air, which may
disturb regular fuel flow in the fuel system,

Mixing of the moisture in the engine oil
can also deteriorate the properties of the
lubricant.

If the use of gasoline containing alcohol
is inevitab le, or presence of al c ohol is
susp ected in the gasoline, it is strongly
recommended to add a filter that has water
separating capability, and check the fuel
syste m for leak s and mechani cal p ar ts
fo r corrosion and abnor m al wear more
frequently.
And, in case any of such abnormalit y is
found, discontinue the use of such gasoline
and contact our dealer immediately.
Damages resulting from the use of gasolines
that contain alcohol are not covered under
