1. SAFETY
SAFETY INFORMATION
For your safety and the safety of
others, pay special attention to these
precautions.
Operator Responsibility
• Gasoline is harmful or fatal if
swallowed. Keep the fuel tank out
of reach of children.
• Gasoline is extremely flammable
and is explosive under certain
conditions. Refuel in a
well-ventilated area with the engine
stopped.
• Do not smoke or allow flames or
sparks where the engine is refueled
or where gasoline is stored.
• Do not overfill the fuel tank. After
refueling make sure that the fuel
tank cap is closed properly and
securely.
• Be careful not to spill any fuel
while refueling. Spilled fuel or fuel
vapor may ignite. If any fuel is
spilled make sure that the area is
dry before starting the engine.
• Know how to stop the engine
quickly in case of emergency.
Understand the use of all controls.
• Do not exceed the boat
manufacturer’s power
recommendation, and be sure that
the outboard motor is properly
mounted.
• Never permit anyone to operate the
outboard motor without proper
instruction.
• Before operating the outboard
motor, familiarize yourself with all
laws and regulations relating to
boating and the use of outboard
motors.
• Do not attempt to modify the
outboard motor.
• Always wear a life-jacket when on
board.
• TOHATSU outboard motor
is designed to give safe and
dependable service if
operated according to
instructions.
Read and understand the
Owner’s Manual before
operating the outboard
motor. Failure to do so
could result in personal
injury or equipment
damage.
Shift to the neutral position
and then shift to the reverse
position at low engine speed.
Do not shift to the reverse
position suddenly at high
engine speed.

SAFETY
• Do not operate the outboard motor
without the engine cover. Exposed
moving parts can cause injury.
• Do not remove any guards, labels,
shields, covers or safety devices;
they are installed for your safety.
• Stop the engine immediately if
anyone falls overboard.
• Do not run the engine while the
boat is near anyone in the water.
• Attach the emergency stop switch
lanyard securely to the operator.
The engine and exhaust system
become very hot during operation and
remain hot for a while after stopping.
Contact with hot engine components
can cause burns and may ignite some
materials.
• Avoid touching a hot engine or
exhaust system.
• Allow the engine to cool before
performing maintenance or
transporting.
Carbon Monoxide Poisoning
Hazard
Exhaust contains poisonous carbon
monoxide, a colorless and odorless
gas. Breathing exhaust can cause loss
of consciousness and may lead to
death.
• If you run the engine in an area that
is confined, or even partially
enclosed, the air can become
contaminated with a dangerous
amount of exhaust gas. To keep
exhaust gas from building up,
provide adequate ventilation.

2. SAFETY LABEL LOCATIONS
These labels are in the locations shown.
They warn you of potential hazards that can cause serious injury.
The label is considered permanent part of your outboard motor.
Read the labels and safety notes and precautions described in this manual carefully.
If a label comes off or becomes hard to read, contact your TOHATSU outboard motor dealer for a replacement.

4. CONTROLS AND FEATURES
Remote Control Lever (R1 type)
Shifting gear into forward, reverse, or
neutral and the engine speed
adjustment can be performed with the
remote control lever.
It is necessary to pull up the neutral
release lever to operate the remote
control lever.
FORWARD:
Moving the lever to the FORWARD
position (i.e. approximately 32° from
the NEUTRAL position) engages the
gear into forward. Moving the lever
further from the FORWARD position
will increase the throttle opening and
the boat forward speed.
NEUTRAL:
Engine power is cut off from the
propeller.
REVERSE:
Moving the lever to the REVERSE
position (i.e. approximately 32° from
the NEUTRAL position) engages the
gear into reverse. Moving the lever
further from the REVERSE position
will increase the throttle opening and
the boat reverse speed.
