IMPORTANT SAFETY

INFORMATION

The Honda BF75D/BF90D 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 injuries or property damage 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.

OUTBOARD MOTOR SAFETY

• 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.

7



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.

• 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 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 partly enclosed, the air you breathe could contain a dangerous amount of exhaust gas.

Never run your outboard inside a garage or other enclosure.

POWER TRIM/TILT SWITCHES

(LEFT) (RIGHT)

The power trim/tilt switch is located on the control lever. It is a rocker switch with UP and DN (down) positions for changing the angle of the outboard motor.

You can use the power trim/tilt switch anytime whether the boat is underway, stopped, or the ignition switch is in the OFF position. It is necessary for the ignition switch to be in the ON position for the trim meter to indicate the outboard motor angle.



Trim the outboard motor to obtain the

best performance and stability (p.67).

Tilt the outboard motor for shallow water operation, beaching, launching, or mooring.

For dual mount outboard motors, tilt them up at the same time.

POWER TILT SWITCH

The power tilt switch is located on the engine pan. It is a rocker switch with

UP and DN (down) positions for changing the angle of the outboard motor.

The power tilt switch will operate without turning the ignition switch

ON.

This switch is used with the engine stopped to raise the outboard motor for mooring, trailering, or maintenance.

MANUAL RELIEF VALVE

The outboard motor can be tilted manually after opening the manual relief valve. This allows the outboard motor to be tilted up or down when no battery is connected.

Check that nobody is under the outboard motor before opening the manual relief valve. If the manual relief valve is loosened (turned counterclockwise) when the outboard motor is tilted up, the outboard motor will suddenly tilt down.

When the boat is to be moored for a long time, tilt the outboard motor up as far as it will go. Then move the tilt lock lever to the LOCK position, and gently lower the outboard motor until the lever contacts the stern bracket.

FIX

The engine cover latch fastens the engine cover to the outboard motor.

34

TRIM TAB

TRIM TAB BOLT

The trim tab compensates for “torque steer,” which is a reaction of the outboard motor to propeller rotation.

If uncompensated, torque steer would make the outboard motor tend to turn to one side.

When the trim tab is correctly

adjusted (p.78), steering effort is

equal in either direction.

INDICATORS

The indicator lights come on and the buzzer sounds when you turn the ignition switch ON, allowing you to see that they are working. If an indicator does not light during this test, it cannot alert you if that system develops a problem. Have your

Honda Marine dealer check for burned-out bulbs or other problems.



Under normal conditions, the following occur when the ignition switch is turned ON:

1. The ACG, Malfunction, Oil 

Pressure, and Overheat indicators light.

2. The buzzer will beep twice.

3. The Malfunction, Oil Pressure, and

Overheat indicators will go out after the second beep.

4. The ACG indicator will go out after the engine starts.

5. The Oil Pressure indicator will light again after the engine starts and will stay lit to indicate the oil pressure is normal.

PROBLEMS

, on p.118.

All models are equipped with a buzzer that sounds continuously when the red light comes on.

The buzzer will also sound when the

hour counter is reset (p.42).

Engine overheating may be the result of clogged water intakes.

Cooling System Indicator

COOLING SYSTEM INDICATOR

Water should flow from the cooling system indicator while the engine is running. This shows that water is circulating through the cooling system.

If water stops flowing while the engine is running, it indicates a cooling system problem, such as clogged water intakes, which will cause engine overheating.

The cooling system indicator discharge port can also become plugged.

38


OTHER FEATURES

Water Separator Buzzer

The water separator buzzer sounds a rapid, repeating signal when water has accumulated in the water separator.

Overrev Limiter

The engine is equipped with an overrev limiter to prevent the possibility of mechanical damage from excessive engine speed.

The overrev limiter may be activated during operation, limiting engine speed, if the outboard motor is trimmed or tilted up excessively, or when propeller ventilation occurs during a sharp turn.

If the overrev limiter is activated, check the trim angle of the outboard motor.

Check to see if the correct propeller is installed.

NMEA2000 network via an optional interface cable. Contact your dealer for more information.

Operating Hour Notification

System

This outboard motor engine counts the number of operating hours since the last periodic maintenance. When the next periodic maintenance is due, the engine notifies the NMEA2000 network, and a maintenance indication is displayed on an

NMEA2000-compatible device.

After periodic maintenance is performed, reset the hour counter by:

1. Stopping the engine.

2. Setting the gearshift at F or R.

3. Turning the ignition switch ON.



The buzzer will sound once.

4. Pressing the emergency stop switch

5 times within 20 seconds.

The buzzer will sound once when the hour counter is reset.

Periodic maintenance is required when either the operating hours or the time since last maintenance reaches the prescribed limit. Therefore, periodic maintenance may be required based on the number of months since the last maintenance before the alert based on engine operating hours displays (see

MAINTENANCE SCHEDULE on

page 76)

Reset the hour counter whenever maintenance is performed, whether based on the time interval or the number of operating hours.

SAFE OPERATING



PRECAUTIONS

To safely realize the full potential of this outboard motor, you need a complete understanding of its operation and a certain amount of practice with its controls.

Before operating the outboard motor for the first time, please review the

IMPORTANT SAFETY

INFORMATION

on page 7 and the

chapter titled BEFORE OPERATION .

For your safety, do not start or run the engine in a confined or partly enclosed area. Your engine’s exhaust contains poisonous carbon monoxide, a colorless, odorless gas that can collect rapidly. Breathing carbon monoxide can cause loss of consciousness and may lead to death.

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. Avoid continuous operation at a steady speed.

First 15 minutes:

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

OPERATION

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. Operating at maximum

4,000~5,000 rpm should be limited to

50% of the 60 minutes.



30-second 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 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. Operating at maximum

2,000~3,000 rpm should be limited to

50% of the 45 minutes.

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.65-66) 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.

OPERATION

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

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.35) for an

indication of whether the outboard motor is trimmed high or low.

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.

Excessive trim/tilt angle during operation can cause propeller ventilation, overheating, and water pump damage. This type of damage is not covered by the Distributor’s

Limited Warranty

(p.134).

The outboard motor can also be tilted manually after opening the manual relief valve. This feature enables the outboard motor to be tilted up or down when no battery is connected.

For manual tilting, use a screwdriver to turn the valve counterclockwise 1 or 2 turns. Close the valve firmly after positioning the engine.

72

Be sure the valve is closed before operating the outboard motor. If the valve is not closed, the outboard motor will tilt up when operated in reverse.


MULTIPLE OUTBOARD

MOTORS

On boats equipped with more than one outboard motor, all motors normally operate at the same time.

If one or more motor(s) is stopped while the other(s) is running, put the stopped motor in “N” (neutral) and tilt it up so its propeller is above the water's surface.

If the propeller of the stopped motor is left in the water, it may turn as the boat moves through the water, causing a reverse flow of water from the exhaust side. This reverse flow will happen if the stopped engine's propeller is in the water, its gearshift is in “R” (reverse), and the boat is moving forward. Reverse flow can cause an engine malfunction.


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.

SERVICING YOUR OUTBOARD MOTOR

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.

TRIM TAB ADJUSTMENT

The trim tab compensates for “torque steer,” which is a reaction of the outboard motor to propeller rotation.

If uncompensated, torque steer would make the outboard motor tend to turn to one side.

When the trim tab is correctly adjusted, steering effort is equal in either direction.

If steering effort is unequal, remove the gear case grommet and loosen the trim tab bolt then adjust the angle of the trim tab. Retighten the trim tab bolt and reinstall the gear case grommet securely.

OIL LEVEL DIPSTICK

3. Insert the dipstick all the way in, and then remove it and check the oil level shown on the dipstick.

4. If the oil level is low, remove the

oil filler cap (p.81), and add oil to

reach the upper limit mark shown on the dipstick. Use the oil

recommended on p.84.

When you check the oil level with the dipstick, you might notice the engine oil appears milky or the oil level has increased. If you notice either condition, change the engine oil. See the following table for an explanation of these conditions.

Operating Method

Running the engine below

3,000 rpm for more than 30% of the time so the engine does not warm up.

Frequent starting and stopping without allowing the engine to warm up.

Result

• Water condenses in the engine and mixes with the oil, resulting in a milky appearance.

• Unburned fuel mixes with the oil, increasing the volume of oil.

Effect

The engine oil deteriorates, becomes less efficient as a lubricant, and causes an engine malfunction.

Gasoline is highly flammable and explosive.





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.

Never refill the fuel tank inside a building where gasoline fumes may reach flames or sparks. Keep gasoline away from appliance pilot lights, barbecues, electric appliances, power tools, etc.

Spilled fuel is not only a fire hazard, it causes environmental damage.

Wipe up spills immediately.

92

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 with percentages of ethanol or methanol greater than shown above are not covered under warranty.

If your outboard motor will be used on an infrequent or intermittent basis, please refer to the fuel section of the

STORAGE

chapter (p.105) for

additional information regarding fuel deterioration.

Fuel

Depending on the region where you operate your outboard, fuel formulations may deteriorate and oxidize rapidly. Fuel deterioration and oxidation can occur in as little as

15 days and may cause damage to the fuel system. Please check with your servicing dealer for local storage recommendations.

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 in less than 15 days, if the gasoline was not fresh when you filled the fuel tank.

You can extend fuel storage life 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.

The Distributor’s Limited Warranty 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

STORAGE

promote fuel deterioration during storage. If you keep an additional container of gasoline for refueling, be sure that it contains only fresh gasoline.

1. Drain the vapor separator before adding fuel stabilizer.

2. Add Honda Marine fuel stabilizer following the instructions on the label.

3. 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.

4. Turn the engine OFF.

Draining the Fuel System

You can avoid fuel deterioration problems by draining the fuel tank and vapor separator.

STORAGE

CUSHION

(protective material)

OUTBOARD MOTOR STAND

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.

(Port side turned down as shown.)

If it is necessary to store the outboard motor horizontally as shown, drain

the vapor separator (p.105) and drain

the engine oil (p.82) before removing

the outboard motor from the boat.

Rest the outboard motor on a cushion of protective material.

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

REMOVAL FROM STORAGE

Check your outboard motor as described in the BEFORE

OPERATION chapter of this manual.

If the cylinders were coated with oil during storage preparation, the engine may smoke briefly at startup. This is normal.

108


WITH OUTBOARD MOTOR

INSTALLED ON BOAT

When trailering a boat with the outboard motor attached, always disconnect the fuel line from the portable fuel tank.

Use an outboard motor support bar to prevent the outboard motor from moving while trailering the boat.

Refer to the manufacturer’s instructions for using an outboard motor support bar.

The preferred method is to leave the engine in the normal running position, but if there is insufficient road clearance, you can tilt the outboard motor using a commercially available outboard motor support bar available through your dealer. Refer to the manufacturer’s instructions for using an outboard motor support bar.

If oil pressure becomes low, the oil pressure indicator will turn off, and the engine protection system limits engine speed. If you are at cruising speed, engine speed will decrease automatically.

The oil pressure indicator is also equipped with a buzzer that sounds when the oil pressure indicator turns off.

Low oil pressure may be the result of a low engine oil level, or there may be a problem with the engine lubrication system.

If the throttle is closed suddenly after full throttle operation, engine speed may drop below the specified idle rpm, and that could activate the engine protection system momentarily.

BUZZER

117



If low oil pressure activates the engine protection system, stop the engine, check the engine oil level

(p.80), and add oil if needed.

With the engine oil at the recommended level, restart the engine. If the lubrication system is

OK, the oil pressure indicator should come on within 30 seconds, and the engine will respond normally to throttle control lever operation.

If the engine protection system remains activated after 30 seconds, return to the nearest boat landing, and have the outboard motor inspected by an authorized Honda Marine dealer.

SUBMERGED OUTBOARD

MOTOR

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

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

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

2. Drain the vapor separator as

described on p.105.

3. Change the engine oil and oil filter

as described on p.82-84. If there

was water in the engine crankcase, or if the used engine oil showed signs of water contamination, then a second engine oil change should be performed after running the engine for half an hour.

4. Remove the spark plugs (p.85).

Operate the starter to expel water from the engine’s cylinders.

5. Pour 1-2 teaspoons (5-10 cm

3

)

(p.107) of engine oil into each

spark plug hole to lubricate the inside of the cylinders. Reinstall the spark plugs.

If the engine 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 engine until it has been repaired.

6. Attempt to start the engine. Be sure the water level is at least 2 inches

(5 cm) above the antiventilation plate.

If you are attempting to start the engine while the outboard motor is out of the water, use commercially available ear muffs and water hose to supply water.

Running the outboard motor without sufficient cooling water will damage the water pump and overheat the engine.

120



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

If the engine starts and no mechanical damage is evident, continue to run the engine for a half hour or longer. Be sure the water level is at least 2 inches

(5 cm) above the antiventilation plate  to avoid overheating and water pump damage.

7. As soon as possible, take the outboard motor to an authorized

Honda Marine dealer for inspection and service.

Battery

For complete information, refer to the battery manufacturer’s instructions.

Minimum Requirements

12V-55Ah/5HR 

(65Ah/20HR) 

(CCA582A)

• Be careful to avoid connecting the battery in reverse polarity, as this will damage the battery-charging system in the outboard motor.

• Do not disconnect the battery cables while the engine is running.

Disconnecting the cables while the engine is running will damage the outboard motor’s electrical system.


• Battery cable extension: Extending the original battery cable will cause the battery voltage to drop due to the increased length of the cable and number of connections.

This voltage drop may cause the buzzer to sound momentarily when engaging the starter motor and may prevent the engine from starting. If the engine starts and the buzzer sounds momentarily, there may be barely sufficient voltage reaching the engine.

WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds. Wash your hands after handling.

Emission Control System

Information

Source of Emissions

The combustion process produces carbon monoxide, oxides of nitrogen, and hydrocarbons. Control of hydrocarbons and oxides of nitrogen is very important because, under certain conditions, they react to form photochemical smog when subjected to sunlight. Carbon monoxide does not react in the same way, but it is toxic.

Honda utilizes appropriate air/fuel ratios and other emissions control systems to reduce the emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons.

Ignition Timing Control System

The system constantly adjusts the ignition timing, reducing the amount of HC, CO, and NOx produced.

123



PGM-FI System

The PGM-FI system uses sequential multiport fuel injection. It has two subsystems: Engine Control and Fuel

Control. The Engine Control Module

(ECM) uses various sensors to determine how much air is going into the engine. It then controls how much fuel to inject under all operating conditions.

The U.S., California Clean Air

Acts, and Environment Canada

EPA, California, and Canadian regulations require all manufacturers to furnish written instructions describing the operation and maintenance of emission control systems.

The following instructions and procedures must be followed in order to keep the emissions from your

Honda engine within the emission standards.

Tampering and Altering

Tampering is a violation of Federal and California law.

Tampering with or altering the emission control system may increase emissions beyond the legal limit.

Among those acts that constitute tampering are:

• Removal or alteration of any part of the intake, fuel, or exhaust systems.

• Alterations that would cause the engine to operate outside its design parameters.

124


Problems That May Affect

Emissions

If you are aware of any of the following symptoms, have your engine inspected and repaired by your servicing dealer.

• Hard starting or stalling after starting.

• Rough idle.

• Misfiring or backfiring under load.

• Afterburning (backfiring).

• Black exhaust smoke or high fuel consumption.


Replacement Parts

The emission control systems on your

Honda engine were designed, built, and certified to conform with EPA and California emission regulations.

We recommend the use of Honda

Genuine parts whenever you have maintenance done. These originaldesign replacement parts are manufactured to the same standards as the original parts, so you can be confident of their performance. The use of replacement parts that are not of the original design and quality may impair the effectiveness of your emission control system.

A manufacturer of an aftermarket part assumes the responsibility that the part will not adversely affect emission performance. The manufacturer or rebuilder of the part must certify that use of the part will not result in a failure of the engine to comply with emission regulations.

Maintenance

Follow the MAINTENANCE

SCHEDULE

on p.76. Remember that

this schedule is based on the assumption that your machine will be used for its designed purpose.

Sustained high-load operation, or use in unusual conditions, will require more frequent service.
