OUTBOARD MOTOR SAFETY
IMPORTANT SAFETY
INFORMATION
Honda BF8D/BFP8D/BF9.9D/
BFP9.9D/BF15D/BFP15D/BF20D
and BFP20D 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.
