IMPORTANT SAFETY

INFORMATION

Honda BF25D and BF30D 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.

OUTBOARD MOTOR SAFETY

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.

7

04/03/15 17:55:05 31ZW2600_009


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 Hazard

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

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.

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

chapter titled

on page 7

and the

BEFORE OPERATION.

For your safety, avoid starting or operating the engine in an enclosed area. Your engine’s exhaust contains poisonous carbon monoxide gas which can collect rapidly in an enclosed area and cause illness or 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.

First 15 minutes:

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

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.

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.

Short 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 8 hours:

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

Engine Speed

For best fuel economy, limit the throttle opening to 80%. Use the

throttle friction control (p.

53 and

54 ) 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.

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

SH, LH, SHG, SRG and LRG

Types

Install the outboard motor at the best trim angle for stable cruising and maximum power.

Trim angle too large: Incorrect causes boat to ‘‘squat’’.

Trim angle too small: Incorrect causes boat to ‘‘plow’’.

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

56

will perform best when the antiventilation plate is level with the water.

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.

LHT, SRT and LRT Types

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 under way 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.

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.

When cruising into a high wind, adjust the outboard motor down slightly to level the boat and improve stability. With a tail wind, adjust the outboard motor up slightly.

77

04/03/15 18:07:52 31ZW2600_079


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.

Occasionally you may hear a light

‘‘spark knock’’ or ‘‘pinging’’

(metallic rapping noise) while operating under heavy loads. This is no cause for concern.

If spark knock or pinging occurs at a steady engine speed, under normal load, change brands of gasoline. If spark knock or pinging persists, see an authorized Honda marine dealer.

Running the engine with persistent spark knock or pinging can cause engine damage.

Running the engine with persistent spark knock or pinging is misuse, and the

Distributor’s Limited

Warranty

does not cover parts damaged by misuse.

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 carburetor deteriorates during storage, you may need to have the carburetor and other fuel system components serviced or replaced.

The length of time that gasoline can be left in your fuel tank and carburetor 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 within a few months, or even less if the gasoline was not fresh when you filled the fuel tank.

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

1.

Add fuel stabilizer following the manufacturer’s instructions.

2.

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 carburetor.

3.

Turn the engine OFF.

STORAGE PRECAUTIONS

Select a well-ventilated storage area.

If possible, avoid storage areas with high humidity.

If storing a container of gasoline, such as the portable fuel tank, store it away from any appliance that operates with a flame, such as a furnace, water heater, or clothes dryer. Also avoid any area with a spark producing electric motor, or where power tools are operated.

OUTBOARD MOTOR STAND

89

04/03/15 18:09:59 31ZW2600_091

STORAGE

If the outboard motor will be removed from the boat for storage, we recommend storing it vertically by mounting it on a stand.

CASE PROTECTOR

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

carburetor (p.

88 ), and drain the

engine oil (p.

72 ), before removing

the outboard motor from the boat.

Position the outboard motor with its carburetor side down, and cushion it with protective packing material.

Cover the outboard motor to keep out dust. Do not use sheet plastic 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.

If oil pressure becomes low, the green indicator light will go off, and the engine protection system will limit engine speed. If you are at cruising speed, engine speed will decrease gradually.

Remote-control type is equipped with a buzzer that sounds when the green indicator light goes off.

The buzzer sound stops below an engine speed of 1,400 rpm.

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.

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

(p.

71 ), and add oil if needed.

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

OK, the green indicator light should come on within 30 seconds, and the engine will respond normally to throttle grip or 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.

Carburetor Modification for

High Altitude Operation

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

A very rich mixture will also foul the spark plugs and cause hard starting.

High altitude performance can be improved by specific modifications to the carburetors. If you always operate your outboard motor at altitudes above 5,000 feet (1,500 meters), have an authorized Honda marine dealer perform this carburetor modification.

Even with carburetor modification, engine horsepower will decrease about 3.5% for each 1,000-foot (300meter) increase in altitude. The effect of altitude on horsepower will be greater than this if no carburetor modification is made.

When the carburetors have been modif ied f or high altitude operation, the air-f uel mixture will be too lean f or low altitude use. Operation at altitudes below 5,000 f eet (1,500 meters) with modif ied carburetors may cause the engine to overheat and result in serious engine damage.

For use at low altitudes, have an authorized Honda Marine dealer return the carburetors to original f actory specif ications.

Oxygenated Fuels

Some conventional gasolines are being blended with alcohol or an ether compound. These gasolines are collectively referred to as oxygenated fuels. To meet clean air standards, some areas of the United States and

Canada use oxygenated fuels to help reduce emissions.

If you use an oxygenated fuel, be sure it is unleaded and meets the minimum octane rating requirement.

Before using an oxygenated fuel, try to confirm the fuel’s contents. Some states/provinces require this information to be posted on the pump.

The following are the EPA-approved percentages of oxygenates:

ETHANOL:

ethyl or grain alcohol;

10% by volume.

You may use gasoline containing up to 10% ethanol by volume. Gasoline containing ethanol may be marketed under the name ‘‘Gasohol’’.

MTBE:

Methyl Tertiary Butyl Ether;

15% by volume.

You may use gasoline containing up to 15% MTBE by volume.

METHANOL:

methyl or wood alcohol; 5% by volume.

You may use gasoline containing up to 5% methanol by volume, as long as it also contains cosolvents and corrosion inhibitors to protect the fuel system. Gasoline containing more than 5% methanol by volume may cause starting and/or performance problems. It may also

106

damage metal, rubber, and plastic parts of your fuel system.

If you notice any undesirable operating symptoms, try another service station, or switch to another brand of gasoline.

Fuel system damage or performance problems resulting from the use of an oxygenated fuel containing more than the percentages of oxygenates mentioned above are not covered under warranty.

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 lean carburetor settings and other systems to reduce the emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons.

The U.S. and Calif ornia Clean

Air Acts

EPA and California 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 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.

107

04/03/15 18:13:24 31ZW2600_109


Problems That May Af f ect

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 genuine Honda parts whenever you have maintenance done. These original-design 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.

67 . 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.
