OUTBOARD MOTOR SAFETY

IMPORTANT SAFETY INFORMATION

The Honda BF40D/BF50D 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 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

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. Do not inhale
exhaust gas. Never run the engine in
a closed garage or confined area.

BREAK-IN PROCEDURE

Break-in period: 10 hours

Proper break-in operation allows the
moving parts to wear in smoothly for
best performance and long service
life.

First 15 minutes:

Run the engine at trolling speed. Use
the minimum throttle opening
necessary to operate the boat at a safe
trolling speed.

Next 45 minutes:

Run the engine up to a maximum of
2,000 to 3,000 rpm, which is about
10% to 30% of maximum throttle
opening.

Next 60 minutes:

Run the engine up to a maximum of
4,000 to 5,000 rpm, which is about
50% to 80% of maximum throttle
opening.

Short full-throttle bursts are OK, but
do not operate the engine
continuously at full throttle.

For boats that plane easily, bring the
boat up on plane, and then reduce the
throttle opening to the recommended
rpm range.

Next 8 hours:

Do not run the engine at full throttle
for more than 5 minutes at a time.

CRUISING

Engine Speed

For best fuel economy, limit the
throttle opening to 80%. Use the
throttle friction control (p. )
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 an
overrev 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 overrev limiter.

−

55 56

If engine speed becomes unstable at
high speed due to activation of the
overrev limiter, reduce speed and
check the trim angle of the outboard
motor.

Trim

LH Type

Install the outboard motor at the best
trim angle for stable cruising and
maximum power.

Trim angle too large: Incorrect
causes boat to ‘‘squat.’’

Trim angle too small: Incorrect
causes boat to ‘‘bow steer.’’

It is necessary to trim the angle of the
outboard motor to compensate for
changes in boat load, weight
distribution, water conditions, or
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.

LRTandXRTTypes

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 trim meter (p. ) for an
indication of whether the motor is

Do not use the tiller handle as a
lever to raise the outboard motor.
Applying excessive f orce to the tiller
handle can damage it.

While the outboard motor is tilted,
proceed at a low speed, and do not
operate the outboard motor in reverse.
The outboard motor will rise
suddenly if operated in reverse.

Monitor water flow from the cooling
system indicator (p. ) to be sure

To raise the outboard motor out of
the water while the engine is stopped
and the boat is moored, or for
maximum clearance when beaching
or launching, use the power tilt
switch (LRT and XRT types) on the
engine pan to tilt the outboard motor
up as far as it will go. Move the tilt
lock lever to the LOCK position, and
then gently lower the outboard motor
until the lever contacts the stern
bracket.

If more clearance is needed to swing
the tilt lock lever into the LOCK
position, rock the outboard motor
forward slightly by pulling on the

THE IMPORTANCE OF MAINTENANCE

Proper maintenance is essential for
safe, economical, and trouble-free
operation. It will also help reduce air
pollution.

Improperly maintaining
this outboard motor, or
failure to correct a problem
before operation, can cause
a malfunction in which you
could be seriously hurt or
killed.

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 f ully
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, replacement, or
repair of the emission control
devices and systems may be
performed by any marine engine
repair establishment or individual,
using parts that are ‘‘certified’’ to
EPA standards.

MAINTENANCE SAFETY Safety Precautions

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.

Failure to properly follow
maintenance instructions
and precautions can cause
you to be seriously hurt or
killed.

Always follow the
procedures and
precautions in the owner’s
manual.

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.

Be sure there is adequate
ventilation whenever you
operate the engine.

−

Burns from hot parts.

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.Let the engine and exhaust

FUEL RECOMMENDATIONS

Use unleaded gasoline with a pump
octane rating of 86 or higher.

Your outboard motor is certified to
operate on unleaded gasoline.
Unleaded gasoline produces fewer
engine and spark plug deposits and
extends exhaust system life.

Never use stale or contaminated
gasoline or an oil/gasoline mixture.
Avoid getting dirt or water in the fuel
tank.

You may use unleaded gasoline
containing no more than 10% ethanol
(E10) or 5% methanol by volume. In
addition, methanol must contain
cosolvents and corrosion inhibitors.

Use of fuels with content of ethanol
or methanol greater than shown
above may cause starting and/or
performance problems. It may also
damage metal, rubber, and plastic
parts of the fuel system.

Engine damage or performance
problems that result from using a fuel

Fuel

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 within a few
months, or even less if the gasoline
was not fresh when you filled the
fuel tank.

You can extend fuel storage lif e 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 vapor separator.

Distributor’s Limited Warranty

The
does not cover fuel system damage
or engine performance problems
resulting from neglected storage
preparation.

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.

Drain the vapor separator before

1.
adding fuel stabilizer.

Add fuel stabilizer following the

2.
manufacturer’s instructions.

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.

Draining the Fuel System

You can avoid fuel deterioration
problems by draining the fuel tank
and vapor separator. Before draining
and checking the f uel system, check
the fuel filter f or contamination and/
or water accumulation. The fuel filter
must be free of any contamination
before proceeding (p. ). Draining
the vapor separator will not drain the
fuel filter bowl.

STORAGE PRECAUTIONS

Select a well-ventilated storage area.
If possible, avoid storage areas with
high humidity.

If storing a container of gasoline,
such as the portable fuel tank
(optional equipment), 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.

92

STORAGE

Any other horizontal storage position
may cause damage to the outboard
motor or oil leakage.

OUTBOARD MOTOR STAND
(commercially available)

If the outboard motor will be
removed from the boat for storage,
we recommend storing it vertically
by mounting it on a commercially
available stand.

CASE PROTECTOR

PROTECTOR

If it is necessary to store the outboard
motor horizontally as shown, drain
the vapor separator (p. ), and
drain the engine oil (p. ), before

72
removing the outboard motor from
the boat.

Position the outboard motor with its
case protector side down, and rest the
motor on a cushion of protective
material.

Cover the outboard motor to keep out
dust. Do not use plastic sheet as a
dust cover. A nonporous cover will
trap moisture, promoting rust and
corrosion.

REMOVAL FROM STORAGE
