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 a horsepower 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 outboard motor should be 0 2 in
(0 50 mm) below the bottom of the boat. When the outboard motor is mounted on a sailboat, the antiventilation plate should be 5.9 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 according to the type of boat and the configuration of the bottom of the boat. Follow the manufacturer’s recommended installation height.

When the outboard motor is installed extremely low, the idle port may be immersed and the engine may become hard to start or may run poorly. Check that the idle port is high enough from the water level when the engine is stopped with the boat fully loaded.
19
Page 22
INSTALLATION
If the outboard motor is installed too low, the boat will squat and be hard to plane, and the motor will spray water that may enter the boat. It will tend to porpoise, and high-speed stability will be reduced.
If the outboard motor is installed too high, that will cause propeller ventilation.
Optimum installation height varies with boat type and 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 accommodate the outboard motor, contact the boat manufacturer and follow their recommendations for corrective action.

OPERATION

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.
31
Transom Angle
Install the outboard motor at the best transom angle for stable cruising and maximum power.
Transom angle too large: Incorrect causes boat to ‘‘squat.’’
Transom angle too small: Incorrect causes boat to ‘‘bow steer.’’
It is necessary to adjust the transom angle of the outboard motor to compensate for changes in boat load, weight distribution, water conditions, or propeller selection.
Under normal running conditions, the boat will perform best when the antiventilation plate is level with the water surface.
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 (p. ).

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.
You may use regular 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 will be used on an infrequent or intermittent basis, please refer to the fuel section of the STORAGE chapter (p. ) for additional information regarding fuel deterioration.
Occasionally you may hear a light ‘‘spark knock’’ or ‘‘pinging’’ (metallic rapping noise) while operating under heavy loads. This is no cause for concern.

Fuel

Depending on the region where you operate your outboard, fuel f ormulations may deteriorate and oxidize rapidly. Fuel deterioration and oxidation can occur in as little as 15 days and may cause damage to the carburetors and fuel system. Please check with your servicing dealer f or 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 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 in less than 30 days, if the gasoline was not fresh when you filled the fuel tank. 2.
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.

3.
Add fuel stabilizer following the manufacturer’s instructions.
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.

OIL PRESSURE INDICATOR GOES OFF AND ENGINE SPEED IS LIMITED

OIL PRESSURE INDICATOR
If oil pressure becomes low, the green indicator will go off. If you are at cruising speed, engine speed will decrease gradually.
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.
41
With the engine oil at the recommended level, restart the engine. If the lubrication system is OK, the green indicator should come on within 30 seconds, and the engine will respond normally to throttle grip 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 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 dealer nearby, take the motor to the dealer immediately. If you are far from a dealer, 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 carburetor as described
2. on p. .
59
Change the engine oil as described
3. on p. . If there was water in the
42 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 plug (p. ),
4. and remove the clip from the engine stop switch. Pull the starter grip, rotate the flywheel a few revolutions to completely expel any water from the cylinder.
If the engine was running when it submerged, there may be mechanical damage, such as a bent connecting rod. If the engine binds when cranked, do not attempt to run the engine until it has been repaired.

Page 72
TAKING CARE OF UNEXPECTED PROBLEMS
Attempt to start the engine.
7.
When cranking the engine with an open ignition circuit (spark plug removed from the ignition circuit), remove the clip from the engine stop switch to prevent possible damage to the ignition system.
Pour a teaspoon of engine oil into
5. the spark plug hole, then pull the starter grip several times to lubricate the inside of the cylinder.
Reinstall the spark plug, and put
6. the emergency stop switch clip into the switch.
If the engine fails to start, remove the spark plug, clean and dry it, then reinstall the spark plug 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.

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 plug and cause hard starting.
High altitude performance can be improved by specific modifications to the carburetor. 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 carburetor has been modif ied for 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 a modified carburetor 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 carburetor to original f actory specif ications.

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 appropriate air/fuel ratios and other emissions control systems to reduce the emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons.
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 AlteringThe U.S. and Calif ornia Clean
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.
73
Page 76
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 Af f ect
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. and . Remember that this
39 40
schedule is based on the assumption that your machine will be used for its designed purpose. Sustained high­load operation, or use in unusual conditions, will require more frequent service.
