OUTBOARD MOTOR SAFETY

IMPORTANT SAFETY INFORMATION

Honda BF25A and BF30A 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

0

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 Understand the use of all controls.

0

Stop the engine immediately if anyone falls overboard, and do not run the engine while the boat is near anyone in the water.

0

Always stop the engine if you must leave the controls for any reason.

of

emergency.

Attach the emergency stop switch lanyard securely to the operator.

0

Always wear a PFD (Personal Flotation Device) while on the boat.

0

Familiarize yourself with all laws

and regulations relating to boating and the use of outboard motors.

0

Be sure that anyone who operates the outboard motor receives proper instruction.

OUTBOARD MOTOR SAFETY

Refuel

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.

Carbon Monoxide

Exhaust gas contains poisonous carbon monoxide. Avoid inhalation of exhaust gas. Never in a closed garage or confined area.

POWER REQUIREMENTS

Before installation, check to be sure that the outboard motor does not exceed the recommended maximum horsepower for the boat on which is

to

be installed. Refer to the boat’s certification plate for recommended maximum horsepower. certification plate information is not available, contact the boat dealer or manufacturer.

For most applications, the outboard

motor should have a horsepower
