Owner's `Manual before operating the Outboard Motor. Failure to do so
could result in personal injury or equipment damage.
To ensure safe operation-
Understand the operation of all controls, and know how to stop the
engine quickly- READ THlS OWNER'S MANUAL CAREFULLY.
Do not exceed the boat manufacturer's power recommendation, and be
sure the outboard motor is properly mounted.
Never permit anyone to operate the outboard motor without proper
Stop the engine immediately if anyone falls overboard.
Do not run the motor while the boat is near anyone in the water.
Exhaust contains poisonous carbon monoxide which can cause un-
consciousness and may lead to death. Never run the outboard in a clos-
ed garage or confined area.
Gasoline is extremely flammable and is explosive under certain condi-
tions. Refuel in a well-ventilated area with the engine stopped.
Do not smoke or allow flames or sparks where the engine is refueled or

Two shaft lengths are available for
the BF2A, either long or short, to
match the transom height of the
1. Installation Position
Install at the stern at the center line
of the boat.
2. Installation Height
For proper propellei depth and engine
cooling, the boat's transom height
must match the motor's shaft
length. The short shaft motor re-
quires a transom height of about 15
in. The long shaft motor requires a
transom of height about 20 in. Once
the boat is in the water and loaded,
check proper motor depth by looking
at the anti-cavitation plate: with the
motor not running, the plate should CAVITATION
be about 100 mm (4 in.) below the
surface of the water.
During operation, check to be sure the anti-cavitation plate remains under
water at all times and that water flows from the water check hole.
Excessive or imbalanced loading will affect the motor's water depth.
Loading too far forward will raise the motor out df the water, reducing
engine cooling. Loading too much or too far rearward will push the motor
deeper, reducing performance.
CAUTION: Insufficient water supply (anti-cavitation plate out of the
water) may cause overheating that will damage the outboard motor.
3. Motor Attachment
Attach the stern bracket to the transom and tighten the clamp screws.
l While operating the boat, check
the tightness of the clamp screws
l Tie a rope through the hole in the
stern bracket and secure the other
end of the rope to the bo,at. This
will prevent accidental loss of the

4. PRE-OPERATION CHECKS
1. Engine Oil Level
l Engine oil is a major factor affecting engine performance and service
life. Nondetergent and low quality oils are not recommended, because
they have inadequate lubricating properties.
l Running the engine with insufficient oil can cause serious engine
Use Honda 4-stroke oil or an equi-
valent high detergent, premium

1. Position the outboard motor vertically, and check the oil level in the oil
level inspection window.
2. If the oil level is down toward the lower level mark on the window, fill
up to the 0.4 e (0.42 U.S. qt.) mark on the dipstick.
OIL LEVEL INSPECTION WINDOW
UPPER LEVEL 0.4 P(0.42 U.S. qt.)
LOWER LEVEL 0.2 P(0.21 U.S. qt.)
2. Fuel Level
Remove the filler cap and check the fuel level. Refill the tank if the fuel
level is low.
NOTE: Open the vent knob before removing the fuel filler cap. When the
vent knob is firmly closed, the cap will be difficult'to remove.
Your engine R `s +esigned to use any gasoline that has a pump oc-
tane number (- ) of 86 or higher, or that has a research octane number
of 91 or higher.2Gasoline pumps at service stations normally display the
pump octane number.
We recommend that you use unleaded fuel because it produces fewer
engine and spark plug deposits and extends the life of exhaust system
Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid
getting dirt, dust or water in the fuel tank. Use of a lower octane gasoline
can cause persistent "pinging" or heavy "spark knock" (a metallic rapp-
ing noise) which, if severe, can lead to engine damage.
CAUTION: If "spark knock" or "pinging" occurs at a steady engine
speed under normal load, change brands of gasoline. If spark knock or
pinging persists, consult your authorized Honda dealer. Failure to do so is
considered misuse, and damage caused by misuse is not covered by
Honda's Limited Warranty.
Occasionally you may experience light spark knock while operating under
heavy loads. This is no cause for concern, it simply means your engine is

FUEL FILLER CAP FUEL TANK
After refueling, be sure to tighten the fuel tank cap firmly.
w Gasoline is extremely flammable and is explosive under certain
l Refuel in a well-ventilated area with the engine stopped. Do not smoke
or allow flames or sparks in the area where the engine is refueled or
where gasoline is stored.
l Do not overfill the tank (there should be no fuel in the filler neck). After
refueling, make sure the tank cap is closed properly and securely.
l Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may
ignite. If any fuel is spilled, make sure the area is dry before starting the
l Avoid repeated or prolonged contact with skin or breathing of vapor.
KEEP OUT OF REACH OF CHILDREN.
GASOLINES CONTAINING ALCOHOL
If you decide to use a gasoline containing alcohol (gasohol), be sure its oc-
tane rating is at least as high as that recommended by Honda. There are
two types of "gasohol": one containing ethanol, and the other containing
methanol. Do not use gasohol that contains more than 10% ethanol. Do
not use gasoline containing methanol (methyl or wood alcohol) that does
not also contain cosolvents and corrosion inhibitors for methanol. Never
use gasoline containing more than 5% methanol, even if it has cosolvents
and corrosion inhibitors.
l Fuel system damage or engine performance problems resulting from the
use of fuels that contain alcohol is not covered under the warranty.
Honda cannot endorse the use of fuels containing methanol since
evidence of their suitability is as yet incomplete.
l Before buying fuel from an unfamiliar station, try to find out if the fuel
contains alcohol; if it does, confirm the type and percentage of alcohol
used. If you notice any undesirable operating symptoms while using a
gasoline that contains alcohol, or one that you think contains alcohol,
switch to a gasoline that you know does not contain alcohol.
3. Other Checks
Check the following items.
@ Propeller, shear pin and cotter pin. Check for looseness or damage.
@ Steering handle. Check for impaired operation.
@ Stern bracket. Check for damage.
@Tool kit. Check for missing spare parts and tools (page 27).
@ Anode metal. Check for looseness, damage or excessive corrosion.
The anode metal helps to protect the outboard motor from corrosion
damage; it must be exposed directly to the water whenever the motor is in
use. Replace the anode metal when it has been reduced to approximately
one half of its original size.
CAUTION:' The possibility of corrosion damage increased if the anode
metal is painted over or allowed to deteriorate.
5. STARTING THE ENGINE
CAUTION: To prevent damage to the outboard from overheating, never
run the engine with the propeller out of the water.
1. Open the fuel cap vent knob 2 to 3 turns.

position, or the boat will move suddenly when the engine starts.
4. In temperatures below 2O'C (68" F) use the choke knob.
5. Pull. the starter rope slowly until resistance is felt, then pull briskly.
CAUTION: Do not allow the starter grip to snap back against the housing;
return it gently by hand to prevent damage to the starter.
6. After starting, be sure water is flowing out of the water check hole.
CAUTION: If water does not flow out, or if steam comes out, stop the
engine. Check to see if the screen in the cooling water inlet is obstructed.
Do not operate the engine until the problem has been corrected.
WATER CHECK HOLE
7. If the choke was used, push it in gradually as the engine warms up.
l Exhaust contains poisonous carbon monoxide gas; exposure can cause
loss of consciousness and may lead to death. Never run the engine in an
enclosed area. Be sure to provide adequate ventilation.
l Be careful not to spill any fuel when refueling. Spilled fuel or fuel vapor
may ignite. If any fuel is spilled make sure the area is dry before starting
If the recoil starter is not working properly, the engine can be started with
the spare starter rope in the tool kit.
1. Remove the engine cover.
2. Remove the recoil starter by removing the three 6 mm nuts.
3. Wind the spare rope clockwise around the pulley, and then pull it to
start the engine.
CAUTION: Keep clear of moving parts.
4. Reinstall the engine cover.
CAUTION: Do not operate without the engine cover. Exposed moving
parts could cause injury and water may damage the engine.
CAUTION: For the first 10 hours of operation, run the outboard motor at
low speed, and avoid abrupt operation of the throttle.
Turn the throttle lever toward FAST to increase speed. For normal cruis-
ing, open the throttle about 3/4.
NOTE: For best performance, passengers ,and equipment should be
distributed evenly to balance the boat.
To turn to the right, swing the steering handle to the left. To turn to the
left, swing the handle to the right.
For smooth steering, adjust the steering friction bolt so that a slight drag is
felt when turning.

STEERING FRICTION BOLT
1. Move the throttle lever to the SLOW position.
CAUTION: Before rotating the motor (from either forward to reverse or
from reverse to forward) reduce the engine speed to SLOW, or the boat
2. To reverse direction, turn the motor 180°, and then pivot the steering
handle as shown.
CAUTION: When operating in reverse, proceed with caution to avoid hit-
ting any under water obstruction with the propeller.
4. Tilting the Motor
Tilt the motor to prevent the propeller and gear case from hitting bottom
when the boat is beached or stopped in shallow water.
1. Stop the engine and turn the fuel valve lever off.
2. Close the fuel cap vent knob.
3. With the motor in the forward position, raise the motor using the carry-
ing handle. The spring-loaded tilt lever will automatically move into
position and hold the motor when it reaches approximately 75'.
4. Adjust the steering friction bolt to keep the motor from moving.
CAUTION: If the 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. If this occurs, refer to the TROUBLE-
SHOOTING section. page 36.
5. To return the motor to the normal RUN position, hold the motor by the
carrying handle and pull the tilt lever toward you, then lower the motor
FU'EL CAP VENT KNOB
CAUTION: Do not transport the motor in the tilted position; it may drop
suddenly causing damage to the boat or the motor.
CAUTION: To avoid damaging the motor, use the utmost care when
mooring the boat, especially when its motor is tilted up. Don't allow the
motor to strike against the pier or other boats.
CAUTION: To avoid damaging the motor, never use it as a handle for lif-
ting or moving the boat.
l High altitude operation
At high altitude, the standard carburetor air-fuel mixture will be excessive-
ly rich. Performance will decrease, and fuel consumption will increase.
High altitude performance can be improved by installing a smaller diameter
main fuel jet in the carburetor and readjusting the pilot screw. If you
always operate the outboard motor at altitudes higher than 6,000 feet
above sea level, have your authorized Honda Outboard Motor dealer per-
form these carburetor modifications.
Even with suitable caburetor jetting, engine horsepower will decrease ap-
proximately 3.5% for each 1,000 foot increase in altitude. The effect of
altitude on horsepower will be greater than this if no carburetor modifica-
tion is made.
CAUTION: Operation of the outboard motor at an altitude lower than the
carburetor is jetted for may result in reduced performance, overheating,
and serious engine damage caused by an excessively lean air/fuel mixture.
7. STOPPING THE ENGINE
1. Move the throttle lever all the way to the left.
2. Push the stop button until the engine stops running.

CAUTION: Used motor oil may cause skin cancer if repeatedly left in
contact with the skin for prolonged periods. Although this is unlikely
unless you handle used oil on a daily basis, it is still advisable to
thoroughly wash your hands with soap and water as soon as possible
after handling used oil.
NOTE: Please dispose of used motor oil in a manner that is compatible
with the environment. We suggest you take it in a sealed container to your
local service station for reclamation. Do not throw it in the trash or pour it
on the ground.
3. Gear Oil Check/Change
Oil Level Check
Check the oil level when the engine is in the vertical position. Remove the
level bolt and see if oil flows out. If no oil comes out, fill through the drain
bolt hole until the oil starts to flow out through the level bolt hole. If there
is water in the oil, the water will flow out first when the drain bolt is
removed, or the oil will be a milky color.
Remove the level bolt and drain bolt to drain the oil. Inject oil through the
drain bolt hole until it starts flowing out through the level bolt hole.
Reinstall and tighten the level bolt and drain bolt securely.
CAUTION: If water is detected in the oil, the unit should be inspected by
an authorized Honda outboard motor dealer.

have an improper heat range may cause engine damage.
6. Cleaning and Flushing
After each use in salt water or dirty water, thoroughly clean and flush the
1. Wash the outside of the outboard motor.with clean, fresh water.
2. Remove the propeller.
3. Stand the motor in a suitable container of water. The water level must
be at least 4 inches above the anti-cavitation plate.
4. Start the engine and run it slowly for at least 5 minutes.
l For safety, the propeller must be removed.
l Be sure the outboard motor is securely mounted, and do not leave it
unattended while running.
l Keep children and pets away from the area, and stay clear of moving
parts during this procedure.
CAUTION: Running the engine without water can cause serious engine
damage due to overheating. Be sure that water flows from the water
check hole while the engine is running. If not, stop the engine and deter-
mine the cause of the problem.
Wipe the outside of the engine with a cloth dipped in clean oil. Apply
marine anti-corrosion grease to the following areas:

1. Remove the cotter pin and the propeller.
2. Remove the broken shear pin and replace it with a new one.
3. Install the propeller.
4. Install a new cotter pin, and spread the ends as shown in the
CAUTION: When replacing the shear pin, be careful not to drop the pro-
peller into the water.
Precautions concerning the propeller
The propeller rotates at high speed when the boat is moving. Before set-
ting off, therefore, check the propeller blades for damage or deformation,
and if there are any abnormalities replace the propeller. Carry a spare pro-
peller in case of an unforeseen accident on the water.
If a spare propeller is not available and an accident does occur, return to
shore carefully while running the engine at low speed.

9. Servicing a Submerged Motor
A submerged motor must be serviced immediately after it is recovered
from the water in order to minimize corrosion.
If there is a Honda outboard motor dealership nearby, take the motor im-
mediately to the dealer. If you are far from a dealership, proceed as
1. Remove the engine cover, and rinse the motor with fresh water to
remove salt water, sand, mud, etc.
2. Drain the fuel tank into a suitable container.
3. Loosen the carburetor drain screw (page 351, drain the contents of the
carburetor into a suitable container, then retighten the drain screw.
4. Change the engine oil (page 28). If there was water in the engine
crankcase, or the used engine oil showed signs of water contamination,
then a second engine oil change should be performed after running the
engine for l/2 hour.
5. Remove the spark plug. While pressing the engine stop button; pull the
recoil starter several times to completely expel water from the cylinder.
l When cranking the engine with an open ignition circuit (spark plug
removed from the ignition circuit), keep the engine stop button depress-
ed to prevent electrical damage to the ignition system.
l If the motor was running when it submerged, there may be mechanical
damage, such as a bent connecting rod. If the engine binds when crank-
ed, do not attempt to run the motor until it has been repaired.
6. Pour a teaspoon of engine oil into the spark plug hole, then pull the
recoil starter several times to lubricate the inside of the cylinder.
Reinstall the spark plug.
7. Attempt to start the engine. If the engine fails to start, remove the
spark plug, clean and dry the electrode, then reinstall the spark plug and
attempt to start the engine again. If the engine starts, and no
mechanical damage is evident, continue to run the engine for l/2 hour
or longer (be sure the water level is at least 4 inches above the anti-

for inspection and service.
1. Drain the water from the extension case.
While depressing the engine stop button to prevent starting, pull the
starter rope several times to expel the water from the extension case.
l Do not rest the motor on its side until the water has been expelled from
the extension case, otherwise water will seep into the exhaust system.
l In cold weather, the water must be expelled from the extension case to
prevent ice from forming in the water pump and water tube.
2. Drain the fuel
1. Turn the fuel valve lever off.
2. Remove the fuel filler cap and drain the gasoline from the fuel tank in-
to a suitable container.
3. Turn the fuel valve lever on, loosen the carburetor drain screw , and
