CRUISING

Engine Speed

For best fuel economy, limit the throttle opening to 80%. Use the throttle friction control (p. ) 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

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 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.

OPERATION

Excessive trim/tilt angle during operation can cause propeller ventilation, overheating, and water pump damage.

STORAGE

Fuel

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.

Distributor’s Limited Warranty

The does not cover fuel system damage or engine performance problems resulting from neglected storage preparation.

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

Disconnect the fuel hose from the

1. outboard motor.

DRAIN SCREW

With the outboard motor in a

2. vertical position, place an approved gasoline container below the fuel drain outlet, and use a funnel to avoid spilling fuel. Loosen the drain screw to drain fuel from the carburetor.

Gasoline is highly flammable and explosive.

You can be burned or seriously injured when handling fuel.

Stop the engine and keep heat, sparks, and flame away. Handle fuel only outdoors. Wipe up spills immediately.

After the fuel has drained from the

3. carburetor, tighten the drain screw securely.

STORAGE

Drain the portable fuel tank into an

4. approved gasoline container, or If you need to store fuel in the fuel tank, you can extend fuel storage life by filling the fuel tank with fresh gasoline and adding a fuel stabilizer that is formulated for that purpose. Firmly close the fuel cap vent knob.

TAKING CARE OF UNEXPECTED PROBLEMS

OIL PRESSURE INDICATOR LIGHT GOES OFF AND ENGINE SPEED IS LIMITED

OIL PRESSURE (GREEN)

(tiller handle type)

(GREEN)

(remote control type)

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 types are equipped with a buzzer that sounds when the green indicator light goes 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.

If low oil pressure activates the engine protection system, stop the engine, check the engine oil level (p. ), 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.

TAKING CARE OF UNEXPECTED PROBLEMS

OVERHEATING INDICATOR LIGHT COMES ON AND ENGINE SPEED IS LIMITED

(RED)

If the engine overheats, the red indicator light will come on, and the engine protection system will limit engine speed. If you are at cruising speed, engine speed will decrease gradually.

Remote-control types are equipped with a buzzer that sounds when the red indicator light comes on.

Engine overheating may be the result of clogged water intake screens, or there may be a problem with the cooling system thermostat or water pump.

If the engine is stopped after running at full throttle, and then restarted soon afterward, that could activate the engine protection system momentarily.

COOLING SYSTEM INDICATOR

If overheating activates the engine protection system, idle the engine in neutral, and check the cooling system indicator.

If water is flowing from the cooling system indicator, continue idling for 30 seconds. If the cooling system is OK, the red indicator light should go off within 30 seconds, and the engine will respond normally to throttle grip or control lever operation.

If there is no water flowing from the cooling system indicator, stop the engine, and tilt the outboard motor to inspect the water intake screens. If clogged, clean the water intake screens, return the outboard motor to the running position, restart the engine, and check the cooling system indicator again.

If there is still no water flowing from the cooling system indicator, or 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.

TAKING CARE OF UNEXPECTED PROBLEMS

SUBMERGED 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 dearship nearby, take the motor to the dealer immediately. If you are far from a dealership, proceed as follows:

Remove the engine cover, and

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

Drain the carburetors as described

2. on p. .

Change the engine oil and oil filter

3. as described on p. . 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.

STARTER GRIP

Remove the spark plugs (p. ),

4. and remove the clip from the

emergency stop or engine switch. Pull the recoil starter grip, rotate the flywheel a few revolutions to completely expel any water from the cylinders.

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.

TAKING CARE OF UNEXPECTED PROBLEMS

Attempt to start the engine.

When cranking the engine with an open ignition circuit (spark plugs removed from the ignition circuit), remove the clip from the emergency or engine stop switch to prevent possible damage to the ignition system.

Pour a teaspoon of engine oil into

5. each spark plug hole, then pull the recoil starter grip several times to lubricate the inside of the cylinders.

Reinstall the spark plugs, and put

6. the emergency stop switch clip into the switch.

If the engine fails to start, remove the spark plugs, clean 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 two inches above the antiventilation plate to avoid overheating and water pump damage.

As soon as possible, take the

8. outboard motor to an authorized Honda Marine dealer for inspection and service.

TECHNICAL AND CONSUMER INFORMATION

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 feet (1,500 meters) with modified 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.

TECHNICAL AND CONSUMER INFORMATION

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:

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:

15% by volume.

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

METHANOL:

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

ethyl or grain alcohol;

Methyl Tertiary Butyl Ether;

methyl or wood

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.

TECHNICAL AND CONSUMER INFORMATION

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. Clean Air Act Tampering and Altering

EPA 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 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.

TECHNICAL AND CONSUMER INFORMATION

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 PartsProblems That May Aff ect

The emission control systems on your Honda engine were designed, built, and certified to conform with EPA emission regulations. We recommend the use of genuine Honda 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. . Remember that this schedule

54 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.
