OUTBOARD MOTOR SAFETY
IMPORTANT SAFETY
INFORMATION
The Honda BF2.3D 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 injuries or property damage can
be prevented if you follow all
instructions in this manual and on the
outboard motor. The most common
hazards are discussed in this chapter,
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.
31ZVA6120.book Page 6 Monday, October 16, 2023 10:33 AM

OUTBOARD MOTOR SAFETY
Refuel With Care
• 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.
Carbon Monoxide Hazard
Exhaust contains poisonous carbon
monoxide, a colorless, odorless gas.
Breathing carbon monoxide can
cause loss of consciousness and may
lead to death.
If you run the engine in an area that is
confined, or even partly enclosed, the
air you breathe could contain a
dangerous amount of exhaust gas.
Never run your outboard inside a
garage or other enclosure.
Running the engine of your
outboard while in an enclosed or
partially enclosed area can cause
a rapid build-up of toxic carbon
monoxide gas.
Breathing this colorless, odorless
gas can quickly cause
unconsciousness and lead to
death.
Only run your outboard engine
when it is located in a well
ventilated area outdoors.

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
Install the outboard motor on the
center of the boat transom.
The antiventilation plate of the
outboard motor should be 0 – 2 in
(0 – 50 mm) below the bottom of the
boat. When the outboard motor is
mounted on a sailboat, the
antiventilation plate should be 6 in
(150 mm) or more below the surface
of the water. For unusual situations,
see your Honda Marine dealer for
advice.
The correct dimensions differ
according to the type of boat and the
configuration of the bottom of the
boat. Follow the manufacturer’s
recommended installation height.

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.
If the outboard motor is installed too
low, the boat will squat and be hard to
plane, and the outboard motor will
spray water that may enter the boat. It
will tend to porpoise, and high-speed
stability will be reduced.
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
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.

OPERATION
STOPPING THE ENGINE
Emergency Engine Stopping
To stop the engine in an emergency,
pull the emergency stop switch clip out
of the emergency stop switch by pulling
the emergency stop switch lanyard.
If the emergency stop switch is
activated while the engine is running,
the engine will shut down abruptly
and the boat will quickly decelerate,
potentially causing occupants and
objects to be thrown forward and/or
overboard.
If the emergency stop switch is
activated, the emergency stop switch
clip must be reinserted before the
engine can be restarted.
We suggest that you stop the engine
this way occasionally to verify that
the engine and emergency stop switch
are operating properly.
Normal Engine Stopping
1. Move the throttle grip to the
SLOW position.
After cruising, cool down the
engine by idling for a few minutes
before stopping the engine.
2. Push the emergency stop switch
button until the engine stops.
In the event that the engine does
not stop when you push the
emergency stop switch, pull the
emergency stop switch lanyard. If
the engine continues to run, move
the fuel valve lever to the OFF
position and pull the choke knob to
stop the engine.

OPERATION
CRUISING
Engine Speed
For best fuel economy, limit the
throttle opening to 80%. Use the
throttle friction control (p. 32) to help
you hold a steady speed.
For rough water conditions or large
waves, slow down to prevent the
propeller from rising out of the water.
Transom Angle
Install the outboard motor at the best
transom angle for stable cruising and
maximum power. See page 24 for
adjustment procedure.
Transom angle too large: Causes boat
to ‘‘squat’’.
Transom angle too small: Causes boat
to ‘‘bow steer’’(Sprayed water may
enter the boat).
It is necessary to adjust the transom
angle to compensate for changes in
boat load, weight distribution, water
conditions, or propeller selection.
Under normal running conditions, the
boat will perform best when the
antiventilation plate (p. 19) is level
with the water surface.
When cruising into a high wind,
decrease the transom angle slightly to
level the boat and improve stability.
With a tail wind, increase the transom
angle slightly.
Excessive transom angle during
operation can cause propeller
ventilation and overheating.

carrying handles on the engine
cover. The spring-loaded tilt lever
will automatically move into
position and hold the outboard
motor when it reaches
approximately 75°.
4. Adjust the steering friction bolt to
keep the outboard motor from
moving.
• Do not use the tiller handle as a
lever to raise the outboard motor.
Applying excessive force to the
tiller handle can damage it.
• If the outboard motor is tilted in the
reverse position, crankcase oil will
enter the cylinder and may cause
difficult starting or may prevent the
engine from being cranked.

MAINTENANCE SAFETY
Some of the most important safety
precautions follow. However, we
cannot warn you of every conceivable
hazard that can arise in performing
maintenance. Only you can decide
whether or not you should perform a
given task.
Safety Precautions
• Make sure the engine is off before
you begin any maintenance or
repairs. This will eliminate several
potential hazards:
─ Carbon monoxide poisoning
from engine exhaust.
Do not start or run the engine in
a confined or partly enclosed
area.
─ Burns from hot parts.
Let the engine and exhaust
system cool before touching.
─ Injury from moving parts.
Do not run the engine unless
instructed to do so.
• Read the instructions before you
begin, and make sure you have the
tools and skills required.
• To reduce the possibility of fire or
explosion, be careful when
working around gasoline. Use only
a nonflammable solvent, not
gasoline, to clean parts. Keep
cigarettes, sparks, and flames away
from all fuel-related parts.
• Wear gloves when handling the
propeller to protect your hands
from sharp edges.
Improper maintenance can cause
an unsafe condition.
Failure to properly follow
maintenance instructions and
precautions can cause serious
injuries or death.
Always follow the procedures
and precautions in this owner's

When you check the oil level in the oil level inspection window, you might
notice the engine oil appears milky or the oil level has increased. If you notice
either condition, change the engine oil. See the following table for an
explanation of these conditions.
Operating Method Result Effect
Running the engine below
3,000 rpm for more than
30% of the time so the

remove mud, salt, seaweed, etc.
Cleaning of the outside of the
outboard motor should be performed
with the engine cover installed.
Be careful not to spray water into the
air intake. If water penetrates inside
the engine cover from the air intake,
it may cause malfunction.
Fuel
Depending on the region where you
operate your outboard, fuel
formulations may deteriorate and
oxidize rapidly. Fuel deterioration
and oxidation can occur in as little as
15 days and may cause damage to the
carburetor and fuel system.
Please check with your servicing
dealer for local storage
recommendations.
Gasoline will oxidize and deteriorate
in storage. Deteriorated gasoline will
cause hard starting, and it leaves gum
deposits that clog the fuel system. If
the gasoline in your fuel tank and
carburetor deteriorates during storage,
you may need to have the carburetor
and other fuel system components
serviced or replaced.
The length of time that gasoline can
be left in your fuel tank and
carburetor without causing functional

STORAGE
problems will vary with such factors
as gasoline blend, your storage
temperatures, and whether the fuel
tank is partially or completely filled.
The air in a partially filled fuel tank
promotes fuel deterioration. Very
warm storage temperatures accelerate
fuel deterioration. Fuel deterioration
problems may occur in less than 15
days, if the gasoline was not fresh
when you filled the fuel tank.
The Distributor’s Limited Warranty
(U.S.) / Distributor’s Warranty (CA.)
(p. 74) does not cover fuel system
damage or engine performance
problems resulting from neglected
storage preparation. See page 51 for
additional information on fuel
recommendations.
You can extend fuel storage life by
adding a gasoline stabilizer that is
formulated for that purpose, or you
can avoid fuel deterioration problems
by draining all the fuel from the fuel
tank and carburetor.
Adding a Fuel Stabilizer
When adding a fuel stabilizer, fill the
fuel tank with fresh gasoline. If only
partially filled, air in the tank will
promote fuel deterioration during
storage. If you keep a container of
gasoline for refueling, be sure that it
contains only fresh gasoline. Contact
your authorized Honda Marine dealer
for stabilizer recommendations.
1. Add Honda Marine fuel stabilizer
or equivalent following the
instructions on the label.
2. After adding a fuel stabilizer, run
the engine outdoors for 10 minutes
to be sure that the treated gasoline
has replaced the untreated gasoline
in the carburetor.
Starting the engine on land:
For safety, remove the propeller from
the outboard motor (p. 53).
• Place a container under the
outboard motor, and fill it with
clean, fresh water. The water level
must be at least 6 inches (15 cm)
above the antiventilation plate.
Running the engine without water can
cause overheating and damage.
Damage caused by running the
outboard motor without water is not
covered by the Distributor’s Limited
Warranty (U.S.) / Distributor’s
Warranty (CA.).
3. Turn the engine OFF, turn the fuel
valve lever to the OFF position
(p. 31), and close the vent knob
(p. 31).

Draining the Fuel Tank and
Carburetor
You can avoid fuel deterioration
problems by draining the fuel tank
and carburetor.
1. With the outboard motor in a
vertical position, place an approved
gasoline container below the fuel
drain outlet, and use a funnel to
avoid spilling fuel.
2. With the engine stopped, turn the
fuel filler cap vent knob to the ON
position to open the fuel vent, and
then remove the fuel filler cap.
3. Loosen the carburetor drain screw
and move the fuel valve lever to the
ON position to drain the carburetor
and the fuel tank into an approved
gasoline container.
4. After draining is completed, tighten
the carburetor drain screw and turn
the fuel valve lever to the OFF
position.
5. Install the fuel filler cap and turn
the vent knob to the OFF position
to close the fuel vent.
Engine Oil
1. Change the engine oil
(p. 42 – 44).
2. Remove the spark plug (p. 48), and
remove the emergency stop switch
clip from the emergency stop
switch.
3. Pour 1 – 2 teaspoons (5 – 10 cm
3
)
of clean engine oil into the
cylinder.
4. Pull the starter grip slowly several
times to distribute the oil in the
cylinder.
5. Reinstall the spark plug (p. 49).
STORAGE PRECAUTIONS
Select a well-ventilated storage area.
If possible, avoid storage areas with
high humidity.
Gasoline is highly flammable and
explosive.
You can be burned or seriously
injured when handling fuel.
• Stop the engine and let it cool
before handling fuel.
• Keep heat, sparks, and flame
away.
• Handle fuel only outdoors.
• Keep away from your vehicle.
• Wipe up spills immediately.

STORAGE
To carry the outboard motor, hold it
by the carrying handle, as shown.
Lifting the outboard motor by the
engine cover, or using the installed
outboard motor as a handle or lever
to move the boat, can damage the
outboard motor.
If your fuel tank contains gasoline,
store it away from any appliance that
operates with a flame, such as a
furnace, water heater, or clothes
dryer. Also avoid any area with a
spark-producing electric motor, or
where power tools are operated.
Store the outboard motor either
vertically or horizontally with the
tiller handle side up.
If storing horizontally, be sure to fold
the tiller handle, and rest the outboard
motor on its case protectors.
Any other horizontal storage position
may cause damage to the outboard
motor or oil leakage.
Cover the outboard motor to keep out
dust. Do not use a plastic sheet as a dust
cover. A nonporous cover will trap
moisture, promoting rust and corrosion.
REMOVAL FROM STORAGE
Check your outboard motor as
described in the BEFORE
OPERATION chapter of this manual.
If the cylinder was coated with oil during
storage preparation, the engine may
smoke briefly at startup. This is normal.

TAKING CARE OF UNEXPECTED PROBLEMS
SUBMERGED OUTBOARD
MOTOR
A submerged outboard motor must be
serviced immediately after it is
recovered from the water in order to
minimize corrosion.
If there is a Honda Marine dealership
nearby, take the outboard motor to the
dealer immediately. If you are far
from a dealer, proceed as follows:
1. Remove the engine cover, and rinse
the outboard motor with fresh
water to remove salt water, sand,
mud, etc.
2. Drain the carburetor as described
on p. 56.
3. Change the engine oil as described
on p. 42 – 44. If there was water in
the engine crankcase, or if the used
engine oil showed signs of water
contamination, then a second
engine oil change should be
performed after running the engine
for half an hour.
4. Remove the spark plug (p. 48),
and remove the emergency stop
switch clip from the emergency
stop switch. Pull the starter grip,
rotate the flywheel a few
revolutions to completely expel any
water from the cylinder.
If the engine was running when it

TECHNICAL INFORMATION
Carburetor Modification for
High Altitude Operation
At altitudes above 3,000 feet
(900 meters), the standard carburetor
air-fuel mixture will be too rich.
Performance will decrease, and fuel
consumption will increase. A very
rich mixture will also foul the spark
plug and cause hard starting.
Operation at an altitude that differs
from that at which this engine was
certified, for extended periods of
time, may increase emissions.
High altitude operation can be
improved by specific modifications
to the carburetor. If you usually
operate your outboard motor at 3,000
feet (900 meters) or above, consult
with your authorized Honda Marine
dealer.
Your dealer can determine the
appropriate carburetor settings for the
altitude at which you operate your
outboard motor.
Even with carburetor modification,
engine horsepower will decrease
about 3.5% for each 1,000-foot
(300-meter) increase in altitude. The
effect of altitude on horsepower will
be greater than this if no carburetor
modification is made.
When the carburetor has been
modified for operation at one of the
higher altitude ranges, the air-fuel
mixture will be too lean for operation
at a lower altitude.
Operation at altitudes below the
range for which the carburetor is set
may cause the engine to overheat and
result in serious engine damage.
For use at lower altitudes, have an
authorized Marine dealer modify the
carburetor for the correct altitude
range.

TECHNICAL INFORMATION
Emission Control System
Information
Source of Emissions
The combustion process produces
carbon monoxide, oxides of nitrogen,
and hydrocarbons. Control of
hydrocarbons and oxides of nitrogen
is very important because, under
certain conditions, they react to form
photochemical smog when subjected
to sunlight. Carbon monoxide does
not react in the same way, but it is
toxic.
Honda utilizes appropriate air/fuel
ratios and other emissions control
systems to reduce the emissions of
carbon monoxide, oxides of nitrogen,
and hydrocarbons.
The U.S., California Clean Air
Acts, and Canadian
Environmental Protection Act
EPA, California, and Canadian
regulations require all manufacturers
to furnish written instructions
describing the operation and
maintenance of emission control
systems.
The following instructions and
procedures must be followed in order
to keep the emissions from your
Honda engine within the emission
standards.
Tampering and Altering
Tampering is a violation of Federal
and California law.
Tampering with or altering the
emission control system may increase
emissions beyond the legal limit.
Among those acts that constitute
tampering are:
• Removal or alteration of any part
of the intake, fuel, or exhaust
systems.
• Alterations that would cause the
engine to operate outside its design
parameters.

TECHNICAL INFORMATION
Problems That May Affect
Emissions
If you are aware of any of the
following symptoms, have your
engine inspected and repaired by your
servicing dealer.
• Hard starting or stalling after
starting
• Rough idle
• Misfiring or backfiring under load
• Afterburning (backfiring)
• Black exhaust smoke or high fuel
consumption
Replacement Parts
The emission control systems on your
Honda engine were designed, built,
and certified to conform with EPA,
California, and Canadian emission
regulations. We recommend the use
of Honda Genuine parts whenever
you have maintenance done. These
original-design replacement parts are
manufactured to the same standards
as the original parts, so you can be
confident of their performance. The
use of replacement parts that are not
of the original design and quality may
impair the effectiveness of your
emission control system.
A manufacturer of an aftermarket part
assumes the responsibility that the
part will not adversely affect
emission performance. The
manufacturer or rebuilder of the part
must certify that use of the part will
not result in a failure of the engine to
comply with emission regulations.
Maintenance
Follow the maintenance schedule on
(p. 40 and 41). Remember that this
schedule is based on the assumption
that your machine will be used for
its designed purpose. Sustained
high-load operation, or use in unusual
conditions, will require more frequent
service.

Emission Control System Warranty
Your new Honda outboard engine complies with both the
U.S. EPA and State of California emission regulations.
American Honda provides the same emission warranty
coverage for outboard engines sold in all 50 states. In all
areas of the United States your outboard engine must be
designed, built, and equipped to meet the U.S. EPA and
California Air Resources Board emission standard for
spark ignited marine engines.
CALIFORNIA EMISSIONS CONTROL SYSTEM
WARRANTY STATEMENT YOUR WARRANTY
RIGHTS AND OBLIGATIONS
The California Air Resources Board (CARB) and
American Honda Motor Co., Inc. are pleased to explain
the emission control system warranty on your 2024 Honda
outboard engine. In California, new outboard engines
must be designed, built, and equipped to meet the state’s
stringent anti-smog standards.
American Honda Motor Co., Inc. must warrant the
emission control system on your outboard engine for the
periods of time listed below provided there has been no
abuse, neglect, or improper maintenance of your outboard
engine.
Your emission control system may include parts such as
the carburetor or fuel injection system, the ignition
system, catalytic converter, canisters, clamps, filters, fuel
caps, fuel lines, fuel tanks, valves, and vapor hoses. Also
included may be hoses, belts, connectors, and other
emission-related assemblies.
Where a warrantable condition exists, American Honda
Motor Co., Inc. will repair your outboard engine at no cost
to you including diagnosis, parts, and labor.

MANUFACTURER’S WARRANTY
COVERAGE:
Select emission control parts from model year 2010 and
later outboard engines are warranted for five years or 250
hours of use, whichever first occurs;
or the length of the Honda Marine Distributor’s Limited
Warranty, whichever is longer. The evaporative emission
control system from model year 2010 and later outboard
engines are warranted for two years with no limit on hours
of use, or the length of the Honda Marine Distributor’s
Limited Warranty, whichever is longer, from the date of
delivery to the retail purchaser. However, warranty
coverage based on the hourly period is only permitted for
engines equipped with hour meters as defined in §
2441(a)(13)* or their equivalent. If any emission-related
part on your engine is defective under warranty, the part
will be repaired or replaced by American Honda Motor
Co., Inc. See the Emission Control System Warranty Parts
table on page 83 for parts description.
* California Code of Regulations.
OWNER’S WARRANTY RESPONSIBILITIES:
As the outboard engine owner, you are responsible for the
performance of the required maintenance listed in your
owner’s manual. American Honda Motor Co., Inc.
recommends that you retain all receipts covering
maintenance on your outboard engine, but American
Honda Motor Co., Inc. cannot deny warranty solely for the
lack of receipts or your failure to ensure the performance
of all scheduled maintenance.
As the outboard engine owner, you should, however, be
aware that American Honda Motor Co., Inc. may deny
you warranty coverage if your outboard engine or a part
has failed due to abuse, neglect, improper maintenance, or
unapproved modifications.
You are responsible for presenting your outboard engine
to a Honda Marine dealer as soon as a problem exists. The
warranty repairs will be completed in a reasonable amount
of time, not to exceed 30 days.

WARRANTY COVERAGE:
See Manufacturer’s Warranty Coverage above for
warranty coverage terms. This warranty is transferred to
each subsequent purchaser for the duration of the warranty
period.
Warranty repairs will be made without charge for
diagnosis, parts, and labor. All defective parts replaced
under this warranty become the property of American
Honda Motor Co., Inc. A list of warranty parts is on page
83. Normal maintenance items, such as spark plugs and
filters, that are on the warranted parts list are warranted up
to their required replacement interval only.
American Honda Motor Co., Inc. is also liable for
damages to other engine components caused by a failure
of any warranted part during the warranty period.
Only Honda approved replacement parts will be used in
the performance of any warranty repairs, and they will be
provided without charge to the owner. You may use any
replacement part as defined in § 1900(b)(20)* in the
performance of any maintenance or repairs. Honda cannot
deny coverage under the emission warranty solely for use
of non-Honda replacement parts or service performed at a
location other than an authorized Honda dealership;
however, use of a part that is not functionally identical to
the original equipment part in any respect that may in any
way affect emissions (including durability) could result in
denial of coverage. If a non-Honda replacement part is
used in the repair or maintenance of your engine, and an
authorized Honda Marine dealer determines it causes the
failure of a warranted part, your warranty claim may be
denied. If the part in question is not related to the reason
that your engine requires repair, your claim will not be
denied.
