INTRODUCTION
A FEW WORDS ABOUT SAFETY
Your safety and the safety of others
are very important. And using this
outboard motor safely is an important
responsibility.
To help you make informed
decisions about safety, we have
provided operating procedures and
other information on labels and in
this manual. This information alerts
you to potential hazards that could
hurt you or others.
Of course, it is not practical or
possible to warn you about all the
hazards associated with operating or
maintaining an outboard motor. You
must use your own good judgment.
You will find important safety information in a variety of forms, including:
Safety Labels
Safety Messages

OUTBOARD MOTOR SAFETY
IMPORTANT SAFETY INFORMATION
Honda BF8D/BFP8D/BF9.9D and
BFP9.9D outboard motors are
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.
Remove any portable fuel tank
from the boat for refueling. Keep
the portable fuel tank away from
the battery or other potential spark
sources.
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.

CONTROLS AND FEATURES
INDICATORS
Oil Pressure Indicator
(R type)
(GREEN)
(H type)
OIL PRESSURE INDICATOR LIGHT
When the green light is lit, oil
pressure is OK.
If oil pressure becomes low, the
green light will go off, and the
engine protection system will limit
engine speed.
Remote controls are also equipped
with a buzzer that sounds when the
green light goes off.
Low oil pressure indicates that the
engine oil level is low, or that there is
a problem with the engine lubrication
system.
Overheating Indicator
(R type)
(RED)
If the engine overheats, the red light
will come on, and the engine
protection system will limit engine
speed.
Remote controls are also equipped
with a buzzer that sounds when the
red light comes on.
Engine overheating may be the result
of clogged water intakes.
22
CONTROLS AND FEATURES
Cooling System Indicator OTHER FEATURES
Overrev Limiter
The engine is equipped with an
overrev limiter to prevent the
possibility of mechanical damage
from excessive engine speed.
The overrev limiter may be activated
during operation, limiting engine
speed, if the outboard motor is tilted
excessively, or when propeller
ventilation occurs during a sharp turn.
COOLING SYSTEM INDICATOR
Water should flow from the cooling
system indicator while the engine is
running. This shows that water is
circulating through the cooling
system.
If water stops flowing while the
engine is running, that indicates a
cooling system problem, such as
clogged water intakes, which will
cause engine overheating.
If the overrev limiter is activated,
check the trim angle of the outboard
motor.
Automatic Choke (R type/HS
type)
The engine is equipped with an
automatic choke so that the choke
system operation is not needed when
starting the engine.
Anodes
ANODES
The anodes are made of a sacrificial
material that helps to protect the
outboard motor from corrosion.
There are two anodes on the gear
case.

PRIMING BULB
INLET END
(TANK)
A priming bulb is built into the fuel
hose that connects the fuel tank to the
outboard motor.
Before starting the engine, squeeze
the priming bulb until it feels firm.
This will ensure that fuel is supplied
to the engine (p. ).
35
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.
BOAT TRANSOM REQUIREMENTS
Honda BF8D/BFP8D/BF9.9D and
BFP9.9D outboard motors can be
installed on a boat transom having a
thickness range of 1.3 2.2 inches
−
(35 57 mm).
−
INSTALLATION POSITION
CENTER LINE
Install the outboard motor on the
center of the boat transom.
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 3.9 inches below the surface of
the water.

25
INSTALLATION
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.

WASHER
Attach the stern bracket to the boat

Attach a rope from the boat to the
hole in the stern bracket. This will
help to prevent accidental loss of the
outboard motor.
You may further secure the outboard
motor by bolting the stern bracket to
the boat transom. Use the optional
mounting bolt and nut kit or other
good quality stainless steel bolts, nuts,
and washers. Apply silicone sealant
to the bolt holes.

BATTERY CONNECTIONS
−
TO ACCESSORIES
BATTERY
Honda BF8D/BFP8D/BF9.9D and
BFP9.9D outboard motors produce a
12-volt, 12-ampere battery-charging
current and are equipped for
connection to a 12-volt battery. The
battery-charging circuit is protected
by a 20-ampere fuse located in the
engine compartment.
The outboard motor’s 12-volt output
is intended for battery charging only.
Lights and electrical accessories for
the boat should be connected to the
battery.
The battery should be kept in a
corrosion-resistant battery box that is
securely mounted in a location away
from the fuel tank and protected
from water and direct sunlight.
Types With Electric Starter
These types are equipped with
battery cables. The positive (+) cable
has a red band at the battery
connector. The negative (-) cable has
a black band at the battery connector.
For electric starter operation, use a
12-volt battery with an ampere-hour
ratingofatleast35Ah.
Types Without Electric Starter
These types are equipped with a 12volt dc battery-charging receptacle
which can be wired to a 12-volt
battery to power lights and electrical
accessories for the boat.

TO ACCESSORIES
To prepare the outboard motor for

The receptacle is provided with a
cover, which should be attached
when the plug is removed, in order to
keep the receptacle clean and dry.
