OUTBOARD MOTOR SAFETY

IMPORTANT SAFETY INFORMATION

The Honda BF2.3D 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

prevented if you follow all

be 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

ickly in case of emergency.

qu Understand the use of all controls.

• Stop the engine immediately if an

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

• Always stop the engine if you must lea

ve the controls for any reason.

• Attach the emergency stop switch lanya

rd securely to the operator.

• Always wear a PFD (Personal Flotat

ion Device) while on the

boat.

• Familiarize yourself with all laws and regulations relating to boati and the use of outboard motors.

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

• Be sure the outboard motor is p

roperly mounted on the boat.

• Do not remove the engine cover while the engine is running.

OUTBOARD MOTOR SAFETY

Refuel With Care

• Gasoline is extremely flammable, and gasoline vapor can explode. Refuel outdoors, in a well-ventilated area, with the

ine stopped. Never smoke near

eng gasoline, and keep other flames and sparks away.

• Refuel carefully to avoid spilling fuel. A

void overfilling the fuel

tank.

• After refueling, tighten the filler cap securely make sure the area is dry before starting the engine.

. If any fuel is spilled,

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 air you breathe could contain a dangerous amount of exhaust gas.

Never run your outboard inside a ga

rage or other enclosure.

INSTALLATION

Correct and secure installation is essential for safe boating and good performance. Follow the installation instructions provided in this manual.

POWER REQUIREMENTS

Before installation, check to be sure that the outboard motor does not exceed the recommended maximum horsepower for the boat on which it is to be installed. Refer to the boat’s certification plate for recommended maximum horsepower. If the certification plate information is not available, contact the boat dealer or manufacturer.

For most applications, the outboard motor should have rating which provides 80% of the maximum recommended horsepower for the boat.

INSTALLATION POSITION

CENTER LINE

Install the outboard motor on the center of the boat transom.

The antiventilation plate of the o

utboard motor should be 0 – 2 in (0 – 50 mm) below the bottom of the boat. When the outboard motor is mounted on antiventilation plate should be 6 in (150 mm) or more below the surface of the water. For unusual situations, see your Honda Marine dealer for advice.

The correct dimensions differ

INSTALLATION

When the outboard motor is installed extremely low, water may enter into the engine under case and negatively affect the performance and durability. When installing, check that the outboard motor is high enough from the water level to keep the engine under case from waves, splash, etc. when the engine is stopped with the boat fully loaded.

on the boat transom.

Optimum installation height varies with boat type a

nd bottom shape. Contact the boat manufacturer for any special recommendations that are unique to a specific model of boat.

If the transom needs to be modified to acc

ommodate the outboard motor, contact the boat manufacturer and follow their recommendations for corrective action.
