SAFETY INFORMATION

For your safety and the safety of others, pay special attention to these precautions.

Operator Responsibility

Honda outboard motor is designed to give safe and dependable service if operated according to instructions.

Read and understand the

Owner’s Manual before operating the outboard motor. Failure to do so could result in personal injury or equipment damage.

Gasoline is harmful or fatal if swallowed. Keep the fuel tank out of reach of children.

Gasoline is extremely flammable and is explosive under certain conditions.

Refuel in a well-ventilated area with the engine stopped.

Do not smoke or allow flames or sparks where the engine is refueled or where gasoline is stored.

Do not overfill the fuel tank.

After refueling make sure that the fuel filler cap is closed properly and securely.

1.

SAFETY

Be careful not to spill any fuel while refueling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled make sure that the area is dry before starting the engine.

The engine can be started even if the gearshift position is in FORWARD or

REVERSE when it is cranked by rope in emergency. To prevent start-in-gear, be sure to set the gearshift position to the

NEUTRAL before starting the engine. Read and understand the Owner’s

Manual before starting the engine in emergency.

05/10/26 09:45:14 3CZW0612_008

SAFETY

Know how to stop the engine quickly in case of emergency.

Understand the use of all controls.

Do not exceed the boat manufacturer’s power recommendation, and be sure that the outboard motor is properly mounted.

Never permit anyone to operate the outboard motor without proper instruction.

Before operating the outboard motor, familiarize yourself with all laws and regulations relating to boating and the use of outboard motors.

Do not attempt to modify the outboard motor.

Always wear a life-jacket when on board.

Do not operate the outboard motor without the engine cover. Exposed moving parts can cause injury.

Do not remove any guards, labels, shields, covers or safety devices; they are installed for your safety.

Stop the engine immediately if anyone falls overboard.

Do not run the motor while the boat is near anyone in the water.

Attach the emergency stop switch lanyard securely to the operator.

The engine and exhaust system become very hot during operation and remain hot for a while after stopping. Contact with hot engine components can cause burns and may ignite some materials.

Avoid touching a hot engine or exhaust system.

Allow the engine to cool before performing maintenance or transporting.

Carbon Monoxide Poisoning

Hazard

Exhaust contains poisonous carbon monoxide, a colorless and odorless gas. Breathing exhaust can cause loss of consciousness and may lead to death.

If you run the engine in an area that is confined, or even partially enclosed, the air can become contaminated with a dangerous amount of exhaust gas. To keep exhaust gas from building up, provide adequate ventilation.

If the operator does not attach the emergency stop switch lanyard, and is thrown from his seat or out of the boat, the outof-control boat can seriously injure the operator, passengers, or bystanders. Always properly attach the lanyard before starting the motor.

The engine does not start unless the clip is set on the emergency stop switch.

INDICATOR LIGHT

A spare emergency stop switch clip is provided near the indicator light.

Use the spare emergency stop switch clip to make the emergency engine start when the emergency stop switch lanyard is not available as, for example, the operator falls outboard.

To prevent damage to the outboard from overheating, never run the engine with the propeller out of water.

OPERATION

Break-in Procedure

Break-in period: 10 hours

Break-in operation allows the mating surfaces of the moving parts to wear evenly and thus ensures proper performance and longer outboard motor life.

Break-in your new outboard motor as follows.

First 15 minutes:

Run the outboard motor at trolling speed. Use the minimum amount of throttle opening necessary to operate the boat at a safe trolling speed.

Next 45 minutes:

Run the outboard motor up to a maximum of 2,000 to 3,000 min

(rpm) or 10% to 30% throttle opening.

Next 60 minutes:

Run the outboard motor up to maximum of 4,000 to 5,000 min

(rpm) or 50% to 80% throttle opening. Short bursts of full throttle are acceptable but do not operate the motor continuously at full throttle.

Next 8 hours:

Avoid continuous full throttle operation (100% throttle opening).

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

For boats that plane easily, bring the boat up on plane then reduce the throttle opening to the specified break-in settings called out above.

MOTOR TRIMMED TOO LOW MOTOR TRIMMED TOO HIGH

Improper trim angle results in unstable steering condition.

Do not trim excessively while cruising through rough waves, or it may cause an accident.

Excessive trim angle can result in cavitation and racing of the propeller, and trimming up the motor excessively can cause damage to the water pump.

MOTOR TRIMMED CORRECTLY

Decrease the trim angle on high speed turns to reduce the possibility of propeller ventilation.

Improper motor trim angle can result in an unstable steering condition.

When cruising:

(A) Into a high wind, trim the motor down slightly to lever the bow and

(B) improve boat stability.

With a tail wind, trim the motor up slightly to raise the bow and improve

(C) boat stability.

Through rough waves, do not trim the motor too low or too high to avoid an unstable steering condition.

OPERATION

When the oil pressure warning system is activated:

1.

2.

Stop the engine immediately and check the engine oil level (see page 47 ).

If the oil is up to the recommended level, restart the engine. If the oil pressure warning system stops after 30 seconds, the system is normal.

If the throttle was closed suddenly after cruising at full throttle, the engine speed may drop below the specified idle speed. This could cause the oil pressure warning system to activate momentarily.

3.

If the oil pressure warning system stays activated after 30 seconds, return to the closest boat landing and contact your closest authorized



When the overheat warning system is activated:

1.

2.

Return the shift lever or control lever to the NEUTRAL position immediately. Check to see if water is flowing out of the cooling water check hole.

If water is flowing out of the cooling water check hole, continue idling for 30 seconds. If the overheat warning system stops after 30 seconds the system is normal.

96

If the motor is turned off after running at full throttle, the engine temperature may rise above normal.

If the motor is restarted, shortly after being turned off, the overheat warning system could be activated momentarily.

COOLING WATER INTAKE PORT

3.

If the overheat warning system stays activated, stop the engine.

Tilt up the motor and check the water intakes for obstructions. If there are no obstructions at the water intakes, return to the closest boat landing and contact your closest authorized Honda outboard motor dealer.

OPERATION

〈 Over-rev Limiter 〉

This outboard motor is equipped with an engine over-rev limiter which activates when the engine speed increases excessively. The over-rev limiter can be activated while cruising, tilting up the motor, or when ventilation occurs during a sharp turn.

When the over-rev limiter is activated:

1.

2.

Reduce the throttle opening immediately and check the trim angle.

If the trim angle is correct but the over-rev limiter stays activated, stop the engine and check the condition of the outboard motor and check the propeller for damage.

Correct or service as necessary, by contacting your authorized Honda outboard motor dealer.

〈 Anodes 〉

Painting or coating the anodes will lead to rust and corrosion damage to the outboard motor.

There are also 2 small sacrificial anodes in the water passages of the engine block.

ANODE

(stern bracket)

ANODE

(each side of extension case)

The anodes are a sacrificial material which helps to protect the outboard motor from corrosion.

97

05/10/26 09:59:46 3CZW0612_098

OPERATION

Shallow Water Operation

Excessive trim/tilt angle during operation can cause the propeller to raise out of the water and cause propeller ventilation and engine over-revving. Excessive trim/tilt angle can also damage the water pump and overheat the engine.

When operating in shallow water, tilt the motor up to prevent the propeller and gear case from hitting the bottom

(refer to pages 86 and 91 ). With the motor tilted up, operate the motor at low speed.

Monitor the cooling system indicator for water discharge. Be sure that the motor is not tilted so high that the water intakes are out of the water.

If an excessive amount of throttle is used when operating in forward gear, the motor will return to the transom angle adjusting rod. (G type)

High Altitude Operation

At high altitude, the standard carburetor air/fuel mixture will be excessively rich. Performance will decrease, and fuel consumption will increase.

High altitude performance can be improved by specific modifications to the carburetor. If you always operate the outboard motor at altitudes higher than 1,500 m (5,000 feet) above sea level, have your authorized Honda dealer perform these carburetor modifications.

Even with suitable carburetor jetting, engine horsepower will decrease approximately 3.5 % for each 300 m

(1,000 foot) increase in altitude. The effect of altitude on the horsepower will be greater than this if no carburetor modification is made.

98

Operation of the outboard motor at an altitude lower than the carburetor is jetted for may result in reduced performance, overheating, and serious engine damage caused by an excessively lean air/fuel mixture.

MAINTENANCE

Submerged Motor Servicing

A submerged motor must be serviced immediately after it is recovered from the water in order to minimize corrosion.

If there is a Honda outboard motor dealership nearby, take the motor immediately to the dealer. If you are far from a dealership, proceed as follows:

1.

2.

Remove the engine cover, and rinse the motor with fresh water to remove salt water, sand, mud, etc.

Drain the carburetor (see page

128 ).

3.

EMERGENCY STARTER ROPE

Remove the spark plugs. Remove the timing belt cover and wind the emergency starter rope following the emergency starting procedure

(pages 70 thru.

73 ) and drain the water from the cylinder by pulling the emergency starter rope several times.

4.

5.

Change the engine oil (see page

111 ).

Pour a teaspoon of engine oil into each spark plug hole, then pull the emergency starter rope several times to lubricate the inside of the cylinders.

Reinstall the spark plugs.

If the motor was running when it submerged, there may be mechanical damage, such as bent connecting rods. If the engine binds when cranked, do not attempt to run the motor until it has been repaired.

126

05/10/26 10:04:40 3CZW0612_127

6.

7.

Install the engine cover and LOCK the FIXING LEVER securely (see page 46 ).

Attempt to start the engine.

If the engine fails to start, remove the spark plugs, clean and dry the electrodes, then reinstall the spark plugs and attempt to start the engine again.

If there was water in the engine crankcase, or the used engine oil showed signs of water contamination, then a second engine oil change should be performed after running the engine for 1/2 hour.

If the engine starts, and no mechanical damage is evident, continue to run the engine for 1/2 hour or longer (be sure the water level is at least 100 mm (4 in) above the anticavitation plate).

8.

As soon as possible, take the motor to a Honda outboard motor dealer for inspection and service.

STORAGE

For longer service life of the outboard motor, have your outboard motor serviced by an authorized

Honda outboard motor dealer before storage. However, the following procedures can be performed by you, the owner, with a minimum of tools.

Carburetor Draining

DRAIN SCREW

( ♯ 1 CARBURETOR)

DRAIN SCREW


5.

6.

After draining thoroughly, tighten the drain screws securely. Be sure to drain thoroughly as the gasoline deteriorates as time goes by.

Connect the drain tube to the original position of the ＃ 4 carburetor securely.



Be careful not to spill fuel.

Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make sure the area is dry before storing or transporting the motor.

Do not smoke or allow flames or sparks where fuel is drained or stored.

DRAIN SCREW

Remove the engine cover (see page 46 ). Disconnect the fuel line connector (see page 103 ).

Pull the ＃ 4 carburetor drain tube outside of the under case.

Loosen the drain screw of the ＃ 4 carburetor and drain the carburetor.

Catch the draining gasoline in a suitable container.

Drain the ＃ 1, ＃ 2 and ＃ 3 carburetors in the same manner using the ＃ 4 carburetor drain tube.

Before storing the outboard motor for a prolonged period, we recommend that you remove the fuel line connector and operate the engine at 2,000 to 3,000 min (rpm) until it stops.
