IMPORTANT SAFETY

INFORMATION

Operator Responsibility

OUTBOARD MOTOR SAFETY

It is the operator’s responsibility to

provide the necessary safeguards

to protect people and property.

Know how to stop the engine

quickly in case of emergency.

Understand the use of all controls.

Attach the emergency stop switch

lanyard securely to the operator.

Stop the engine immediately if

anyone falls overboard, and do not

run the engine while the boat is

near anyone in the water.

Always stop the engine if you

must leave the controls for any

reason.

Always wear a PFD (Personal

Flotation Device) while on the

boat.

Familiarize yourself with all laws

and regulations relating to boating

and the use of outboard motors.

Be sure that anyone who operates

the outboard motor receives proper

instruction.

Be sure the outboard motor is

properly mounted on the boat.

Do not remove the engine cover

while the engine is running.

Most accidents can be prevented if

you follow all instructions in this

manual and on the outboard motor.

The most common hazards are

discussed below, along with the best

way to protect yourself and others.

Honda BF2D outboard motor is

designed for use with boats that have

a suitable manufacturer’s power

recommendation. Other uses can

result in injury to the operator or

damage to the outboard motor and

other property.

Carbon Monoxide HazardRefuel With Care

OUTBOARD MOTOR SAFETY

Exhaust gas contains poisonous

carbon monoxide. Avoid inhalation

of exhaust gas. Never run the engine

in a closed garage or confined area.

Gasoline is extremely flammable,

and gasoline vapor can explode.

Refuel outdoors, in a well-

ventilated area, with the engine

stopped. Never smoke near

gasoline, and keep other flames

and sparks away.

Refuel carefully to avoid spilling

fuel. Avoid overfilling the fuel

tank.

After refueling, tighten the filler

cap securely. If any fuel is spilled,

make sure the area is dry before

starting the engine.

SAFETY LABEL LOCATIONS

OUTBOARD MOTOR SAFETY

The labels shown here contain important safety information. Please read them carefully. These labels are considered

permanent parts of your outboard motor. If a label comes off or becomes hard to read, contact an authorized Honda

Marine servicing dealer for a replacement.

Loosen the wing nut to free the

adjusting bolt.

Adjust the angle of the outboard

motor, and tighten the wing nut. Be

sure that the bolt head and wing nut

are seated in one of the four recesses

in the adjustment slot.

To return the outboard motor to the

normal running position, hold the

outboard motor and pull the tilt lever,

then slowly lower the outboard motor.

The tilt lever enables the outboard

motor to be tilted for shallow water

operation, beaching, launching, or

mooring.

Tilt the outboard motor by holding

the carrying handles, as shown. The

spring-loaded tilt lever will

automatically move into position and

hold the outboard motor when it

reaches approximately 75°.

Correct and secure installation is

essential for safe boating and good

performance. Follow the installation

instructions provided in this manual.

Transom Height

Before installation, check to be sure

that the outboard motor does not

exceed the recommended maximum

horsepower for the boat on which it

is to be installed. Refer to the boat’s

certification plate for recommended

maximum horsepower. If the

certification plate information is not

available, contact the boat dealer or

manufacturer.

For most applications, the outboard

motor should have a horsepower

rating which provides 80% of the

maximum recommended horsepower

for the boat.

The antiventilation plate of the

outboard motor should be 0 2.0

inches below the bottom of the boat.

With the boat in the water and loaded,

the antiventilation plate should be

about 5.9 inches below the surface of

the water.

Type:

Install the outboard motor on the

center of the boat transom.

ATTACHMENT

INSTALLATION

CLAMP SCREW

STERN BRACKET

SAFETY ROPE

If the outboard motor is installed too

low, the boat will squat and be hard

to plane, it will tend to porpoise, and

high-speed stability will be reduced.

If the outboard motor is installed too

high, that will cause ventilation.

Optimum installation height varies

with boat type and bottom shape.

Contact the boat manufacturer for

any special recommendations that are

unique to a specific model of boat.

If the transom needs to be modified

to accommodate the outboard motor,

contact the boat manufacturer and

follow their recommendations for

corrective action.

Attach the stern bracket to the boat

transom by tightening the clamp

screws.

Attach a rope from the boat to the

hole in the stern bracket. This will

help to prevent accidental loss of the

outboard motor.

TRANSOM ANGLE

ADJUSTMENT

INSTALLATION

Use the transom angle adjustment

bolt (p. ) to adjust the angle of the

outboard motor so the propeller is

perpendicular to the surface of the

water.

？

Improperly maintaining

this outboard motor, or

failing to correct a problem

before operation, could

cause a malfunction in

which you could be

seriously injured.

Always perform a

preoperation inspection

before each operation, and

correct any problem.

IS YOUR OUTBOARD

MOTOR READY TO GO

BEFORE OPERATION

Your safety is your responsibility. A

little time spent in preparation will

significantly reduce your risk of

injury.

Read and understand this manual.

Know what the controls do and how

to operate them.

Familiarize yourself with the

outboard motor and its operation

before you get under way. Know

what to do in case of emergencies.

Familiarize yourself with all laws

and regulations relating to boating

and the use of outboard motors.

Always wear a PFD (Personal

Flotation Device) while on the boat.

Attach the emergency stop switch

lanyard securely to your PFD or to

your wrist.

For your safety, and to maximize the

service life of your equipment, it is

very important to take a few

moments before you operate the

outboard motor to check its condition.

Be sure to take care of any problem

you find, or have your authorized

Honda Marine dealer correct it,

before you operate the outboard

motor.

Safety Inspection Maintenance Inspection

BEFORE OPERATION

Look around the outboard motor

for signs of oil or gasoline leaks.

Check the engine oil level (p. ).

Running the engine with a low oil

level can cause engine damage.

Wipe up any spills before starting

the engine.

Check the stern bracket to be sure

the outboard motor is securely

installed.

Check that all controls are

operating properly.

Replace any damaged parts.

Check that all fasteners are in

place and securely tightened.

Check to be sure the propeller is

undamaged (p. ).

Check that the anode is securely

attached to the antiventilation plate

(p. ) and is not excessively

worn. The anode helps to protect

the outboard motor from corrosion.

Make sure the tool kit and

emergency starter rope are

onboard (p. ). Replace any

missing items.

Check the fuel level in the fuel

tank (p. ).

IMPORTANT SAFETY

INFORMATION

BEFORE OPERATION.

To prevent damage to the motor or

boat, make sure the transom angle

adjusting bolt is locked.

To safely realize the full potential of

this outboard motor, you need a

complete understanding of its

operation and a certain amount of

practice with its controls.

Before operating the outboard motor

for the first time, please review the

on page and the

chapter titled

For your safety, avoid starting or

operating the engine in an enclosed

area. Your engine’s exhaust contains

poisonous carbon monoxide gas

which can collect rapidly in an

enclosed area and cause illness or

death.

The transom angle adjusting bolt is

used to adjust the angle of the

outboard motor in the normal

operating position (p. ).

To adjust, first tilt the outboard

motor so it is not resting on the bolt.

There are four adjustment positions.

Loosen the wing nut to free the

adjusting bolt.

Adjust the angle of the motor, and

tighten the wing nut. Be sure that

the bolt head and wing nut are

seated in one of the four

adjustment positions.

Proper break-in procedure allows the

moving parts to wear in smoothly for

best performance and long service

life.

For the first 10 hours, run the

outboard motor at low speed, and

avoid full-throttle operation.
