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 MOV-

ING 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 over-

board.

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 (Per-

sonal Floatation Device) while on the boat.

ENOM00010-0

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 67). It is the opera-

tor's responsibility to perform all safety checks and to ensure that all lubrication and main-

tenance 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.
