IMPORTANT SAFETY
INFORMATION
Honda BF350A 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.
OUTBOARD MOTOR SAFETY
7
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.
WARNING
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.

Function switches are used for
operations in the fast idle mode
and trolling mode.
NT (WARM)
● Lights: The gearshift is in
neutral.
●
Blinks: It is in the fast idle
mode.
ACT
● Lights: The gearshift and
throttle operations are
possible.
● Off: The gearshift and throttle
operations are not possible.
Fast Idle Mode
The BF350A model uses
programmed fuel injection, so
this mode will not be needed for
starting.
After the engine starts and if the
outside temperature is below
41°F (5°C), the fast idle mode can
be used to accelerate engine
warm-up.
See page 60 for engine warm-
up instructions.
Use the [-] switch and the
gearshift/throttle control lever to
adjust the engine speed without
the gearshift when warming up
the engine.

Keeping the [-] switch pressed

Keep turning the lever forward.
The throttle opens and the
engine speed increases after the
lever passes the shift point.
Note that the gearshift
mechanism does not function
when the [-] switch is pushed
once and then released after the
gearshift/throttle control lever is
moved.
The control lever does not
operate unless the neutral release
lever is pulled.
To release the fast idle mode,
press and hold the [-] switch with
the gearshift/throttle control
lever in the NEUTRAL position.
Trolling Mode
After the engine warms up, when
the gearshift/throttle control
lever is tilted from the NEUTRAL
position to the FORWARD or
REVERSE side by about 20° and
the [+] switch is pressed and
held, the mode changes to
trolling mode.
Engine speed adjusting range:
650 rpm – 1,000 rpm (every 50
rpm)
When in trolling mode, trolling
mode is not released even if you
put the gearshift/throttle control
lever in the NEUTRAL position. By
shifting from NEUTRAL to
FORWARD or REVERSE again, the
boat will cruise at the set engine
speed.

CAUTION
While in trolling mode, be
careful when shifting the
gearshift/throttle control lever
from the NEUTRAL position to
the FORWARD or REVERSE
position. Operating the
gearshift/throttle control lever
while trolling mode is ON
creates a risk of collision or
injury due to an unexpected
sudden start, which is caused
by the engine starting to cruise
at the speed set for trolling
mode, not by how far the
throttle is opened.
● If the engine is not finished
warming up, it cannot go into
trolling mode. So, warm up
the engine (P. 60).
● You can force the release of
trolling mode by using the
gearshift/throttle control lever
to increase the engine speed
to 3,000 rpm or higher.
● To release the trolling mode,

CRUISING
Engine Speed
For best fuel economy, limit the
throttle opening to 80%. Use the
throttle friction control (P.66) 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.
The engine is equipped with a rev
limiter to prevent the possibility
of mechanical damage from
excessive engine speed.
If, for example, the outboard
motor is tilted excessively or
propeller ventilation occurs
during a sharp turn, the engine
may overrev, activating the rev
limiter.
If engine speed becomes
unstable at high speed due to
activation of the rev limiter,
reduce speed and check the trim
angle of the outboard motor.
WARNING
Traveling at high speeds may
cause the boat to loss of
control in some water
conditions, which could result
in damage to the outboard
motor and injury to the
occupants.
Always travel at safe speeds for
the water conditions.
Trim
Use the power trim/tilt switch to
trim the outboard motor for the
best performance and stability.
You can use the power trim/tilt
switch at any time, whether the
boat is underway or stopped.
Press the UP or DN (down) side
of the switch to adjust the angle
of the outboard motor.
Refer to the multi-function
display or NMEA2000-compatible
display for an indication of
whether the outboard motor is
trimmed high or low.
OPERATION
69
It is necessary to trim the angle of
the outboard motor to
compensate for changes in boat
load, weight distribution, water
conditions, and propeller
selection.
Under normal conditions, the
boat will perform best when the
antiventilation plate is level with
the water surface.
When cruising into a high wind,
trim the outboard motor down
slightly to level the boat and
improve stability. With a tail wind,
trim the outboard motor up
slightly.
NOTICE
• Excessive trim/tilt angle
during operation can cause
propeller ventilation,
overheating, and water
pump damage.

If the propeller of the stopped
motor is left in the water, it may
turn as the boat moves through
the water, causing a reverse flow
of water from the exhaust side.
Reverse flow can cause an engine
malfunction.
NOTICE
• If one outboard is down and
another outboard is tilted all
the way up, it may cause
extreme steering angles that
can cause the outboard

THE IMPORTANCE OF
MAINTENANCE
Proper maintenance is essential
for safe, economical, and trouble-
free operation. It will also help
reduce air pollution.
WARNING
Failure to properly maintain this
outboard motor, or failing to
correct a problem before
operation, could result in a
significant malfunction.
Some malfunctions can cause
serious injuries or death.
Always follow the inspection
and maintenance
recommendations and
schedules in this owner's
manual.
To help you properly care for
your outboard motor, the
following pages include a
maintenance schedule, routine
inspection procedures, and
simple maintenance procedures
using basic hand tools. Other
service tasks that are more
difficult or require special tools
are best handled by professionals
and are normally performed by a
Honda technician or other
qualified mechanic.
The maintenance schedule
applies to normal operating
conditions. If you operate your
outboard motor under unusual
conditions, consult an authorized
Honda Marine dealer for
recommendations applicable to
your individual needs and use.
Remember that your authorized
Honda Marine dealer knows your
outboard motor best and is fully
equipped to maintain and repair
it.
To ensure the best quality and
reliability, use only new, Honda
Genuine parts or their equivalents
for repair and replacement.

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.
WARNING
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
manual.
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 them.
− 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.

oil, increasing the volume of oil.
The engine oil deteriorates,
becomes less efficient as a
lubricant, and causes an engine
malfunction.

NOTICE
• 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 fuel
system. Please check with
your servicing dealer for
local storage
recommendations.
Gasoline will oxidize and
deteriorate in storage. Old
gasoline will cause hard starting,
and it leaves gum deposits that
clog the fuel system. If the
gasoline in your fuel tank and
vapor separator deteriorates
during storage, you may need to
have the vapor separator and
other fuel system components
serviced or replaced.
The length of time that gasoline
can be left in your fuel tank and
vapor separator without causing
functional 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.
You can extend fuel storage life

Storage Procedure
WARNING
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.
1. Remove the engine cover (P.
91).
2. Inspect the fuel filter with
water separator (low-pressure
side).
If water has collected inside it
or there is a clog, such as
sediment in the cup, then
remove the water or replace
the filter. (P.109)
3. Drain the gasoline from the
drain screw of the vapor
separator. (P.120)
4. Confirm that there is no water
or dirt mixed in with the
gasoline that you remove.
5. Do the following operation if
you find water or dirt mixed in
with the gasoline that you
remove.
a Confirm that the drain
screw has been tightened.
b Keep the motor level as
you connect a gas tank
that has fresh gasoline.
STORAGE
118
c Use the primer bulb to
supply fresh gasoline to
the vapor separator.
CAUTION
Always operate the primer bulb
while the drain screw is tight. If
the drain screw is loose, then
gas will leak.
d Start the engine and run it
at idle for 1 minute.
NOTICE
• Always start the engine
under normal operating
conditions (while the
propeller is in the water).
Never start it while the
propeller is out of the water.
Doing so will damage the
engine.
e
Drain the gasoline from
the drain screw of the
vapor separator. (P.120)
f Confirm that there is no
water or dirt mixed in with
the gasoline that you
remove.
g If you find water or dirt in
the gasoline that you
remove, then repeat steps
a to f until you can
confirm there is no water
or dirt.
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 an additional container
of gasoline for refueling, be sure
that it contains only fresh
gasoline.
1. Drain the vapor separator
before adding fuel stabilizer.
2. Add Honda Marine fuel
stabilizer or equivalent
following the instructions on
the label.
3. After adding a fuel stabilizer,
run the engine in water for 10
minutes to be sure that the
treated gasoline has replaced
the untreated gasoline in the
vapor separator.
4. Turn the engine OFF.

121
STORAGE PRECAUTIONS
Select a well-ventilated storage
area. If possible, avoid storage
areas with high humidity.
If storing a container of 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.
If the outboard motor will be
removed from the boat for
storage, store it vertically by
mounting it on a commercially
available stand.
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

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.
PGM-FI System
The PGM-FI system uses
sequential multiport fuel
injection. It has three subsystems:
Air Intake, Engine Control, and
Fuel Control. The Engine Control
Module (ECM) uses various
sensors to determine how much
air is going into the engine. It
then controls how much fuel to
inject under all operating
conditions.
Ignition Timing Control System
The system constantly adjusts the
ignition timing, reducing the
amount of HC, CO, and NOx
produced.
TECHNICAL INFORMATION
141
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
NOTICE
• 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:
●
Alterations that would cause
the engine to operate outside
its design parameters.
●
Removal or alteration of any
part of the intake, fuel, or
exhaust systems.
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
TECHNICAL INFORMATION
142
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.
Honda cannot deny coverage
under the emission warranty
solely for the use of non-Honda
replacement parts or service
performed at a location other
than an authorized Honda
dealership; you may use
comparable EPA certified parts,
and have service performed at
non-Honda locations. However,
the use of replacement parts that
are not of the original design and
quality may impair the
effectiveness of your emissions
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
As the outboard engine owner,
you are responsible for
completing all required
maintenance listed in your
owner's manual. Honda
recommends that you retain all
receipts covering maintenance on
your outboard engine, but Honda
cannot deny warranty coverage
solely for the lack of receipts or
for your failure to ensure that all
scheduled maintenance has been
completed.
Follow the MAINTENANCE
SCHEDULE on page 88.
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.

Warranty
Please read the warranty
statements contained in this
manual. There are responsibilities,
restrictions, and exclusions that
apply to these warranties.
To obtain warranty service you
must take your Honda outboard
motor, together with proof of
original retail purchase date, at
your expense, to a Honda engine
dealer or distributor authorized
to sell that product in the United
States, Puerto Rico, the U.S.
Virgin Islands or Canada.

warranty applies to defects in
material or workmanship of your
Honda. Your warranty coverage
does not apply to normal wear or
deterioration associated with
using your Honda outboard
motor.
CONSUMER INFORMATION
149
Your warranty coverage will not
be voided if you choose to
perform your own maintenance.
However, you should have the
proper tools and service
information and be mechanically
qualified. Failures that occur due
to modifications, improper
maintenance, or service are not
covered.
Warranty Service
Please remember that
recommended maintenance
interval servicing is not included
in your warranty coverage.
Additionally, your warranty does
not apply to the normal wear of
items (such as spark plug(s),
water pump, etc.).
As the owner of a Honda
product, your servicing dealer
may ask you to authorize an
inspection. If the problem is
covered under warranty, your
dealer will perform any warranty
repairs for you at no cost.
However, you may be responsible
for additional non-warranty
charges.
If you have questions about
warranty coverage or the nature
of the repair, it is best to talk to
the service manager of your
Honda dealer.
Sometimes, in spite of the best
intentions of all concerned, a
misunderstanding may occur. If
you aren’t satisfied with your
dealer’s handling of the situation,
we suggest you discuss your
problem with the appropriate
member of the dealership’s
management team. If the
problem has already been
reviewed with the appropriate
manager of the Service, Parts, or
Sales department, contact the
owner of the dealership or their
designated representative.

Only Honda approved replacement parts will be

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.

Claims for repair or adjustment found to be caused

be denied because the engine was not properly
maintained and used.

contact the owner of the dealership involved.
Normally this should resolve your problem.
