OUTBOARD MOTOR SAFETY
IMPORTANT SAFETY
INFORMATION
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.
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.
Operator Responsibility
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.
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.
Attach the emergency stop switch
lanyard securely to the operator.
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.

OUTBOARD MOTOR SAFETY
Carbon Monoxide HazardRefuel With Care
Gasoline is extremely flammable,
and gasoline vapor can explode.
Refuel outdoors, in a wellventilated 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.
Exhaust gas contains poisonous
carbon monoxide. Avoid inhalation
of exhaust gas. Never run the engine
in a closed garage or confined area.

INSTALLATION
Correct and secure installation is
essential for safe boating and good
performance. Follow the installation
instructions provided in this manual.
POWER REQUIREMENTS
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.
INSTALLATION POSITION
CENTER LINE
Install the outboard motor on the
center of the boat transom.
The antiventilation plate of the
outboard motor should be 02.0
−
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.

INSTALLATION
When the outboard motor is installed
extremely low, water may enter into
the engine under case and negatively
affect the performance and durability.
When installing, check that the
outboard motor is high enough from
the water level to keep the engine
under case from waves, splash, etc.
when the engine is stopped with the
boat fully loaded.
Propeller ventilation will occur if the
outboard motor is installed too high
on the boat transom.
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.
ATTACHMENT
STERN BRACKET
SAFETY ROPE
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.

BEFORE OPERATION
ARE YOU READY TO GET
UNDER WAY?
Your safety is your responsibility. A
little time spent in preparation will
significantly reduce your risk of
injury.
Knowledge
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.
Safety
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.
IS YOUR OUTBOARD
MOTOR READY TO GO?
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.
Improperly maintaining
this outboard motor, or
failing to correct a problem
before operation, can cause
a malfunction in which you
could be seriously hurt or
killed.
Always perform a
preoperation inspection
before each operation, and
correct any problem.

Safety InspectionMaintenance Inspection
BEFORE OPERATION
Look around the outboard motor
for signs of oil or gasoline leaks.
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 the engine oil level (p.).
Running the engine with a low oil
level can cause engine damage.
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
49
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.

BREAK-IN PROCEDURE
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.
TRANSOM ANGLE
ADJUSTMENT
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
1.
adjusting bolt.
Adjust the angle of the motor, and
2.
tighten the wing nut. Be sure that
the bolt head and wing nut are
seated in one of the four
adjustment positions.
To prevent damage to the motor or
boat, make sure the transom angle
adjusting bolt is tight.
