GENERAL SAFETY INFORMATION

ENOM00009-1

SAFE OPERATION OF BOAT

As the operator/driver of a 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 out-

board motor, please read through this manual carefully.

It is very difficult for a person 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 out-

board motor must 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.

ENOM00247-1

STOP SWITCH LANYARD

The engine can be stopped by pulling out the stop switch lock from the stop switch. The

stop switch lanyard is the coiled red cord with the stop switch lock on one end and a

metal clip on the other end. With attaching the stop switch lanyard to the operator's

body part or operator’s personal flotation device (PFD), the engine will stop when the

stop switch lanyard is being stretched and pulled out the lock from the switch if the

operator accidentally falls overboard or leaves from operator’s position. This function

may prevent losing control of the boat and minimize or prevent risk of collision with

other boats, people and other objects. It is operator’s responsibility to use the stop

switch lanyard.

ENOW00004-1

Accidental activation of the 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 Stop Switch, the 500 mm (20 inch.) stop switch lan-

yard is coiled and can extended to a full 1300 mm (51 inch.).

ENOM00800-A

PERSONAL FLOTATION DEVICE

As the operator/driver and passenger of a boat, you are responsible to wear a PFD (Per-

sonal Flotation Device) while on the boat.

WARNING

GENERAL SAFETY INFORMATION 11

ENOM00010-1

SERVICING, REPLACEMENT PARTS & LUBRICANTS

We recommend that only an authorized service shop perform service or maintenance

on your outboard motor. Be sure to use genuine parts, genuine lubricants, or recom-

mended lubricants. Be aware that the installation and use of parts not approved by

Tohatsu Corporation will void warranty and may lead to unsafe operating conditions.

ENOM00011-1

MAINTENANCE

As the owner of the outboard motor, you should be acquainted with correct mainte-

nance procedures following by maintenance section of this manual (See page 59). It is

the operator's responsibility to perform all safety inspections, proper lubrication and to

follow all maintenance instructions for safe operation. 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 outboard motor will reduce the

chance of problems, limit overall operating expenses and contribute to longevity of your

outboard motor.

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.

Most boats are rated and certified for 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.

ENOW00009-2A

zMounting the outboard motor without

following this manual can lead to unsafe

conditions such as poor maneuverability,

lack of control or fire.

zLoose clamp screws and/or mounting

hardware can lead to the release or dis-

placement of the outboard motor, possi-

bly resulting in loss of control and/or

serious personal injury. Be sure that fas-

teners are tightened to the specif ied

torque. Check the fasteners for tightness

before operating your outboard.

zBe sure to use outboard mounting hard-

ware included in the outboard m otor

package or their equivalents in terms of

size, material, quality and strength.

Keep the outboard motor in a vertical

position when mounting.
