Honda Outboard Motors are 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.

To ensure safe operation-

* Understand the operation of all controls, and know how to stop the

engine quickly- READ THIS OWNER’S MANUAL CAREFULLY.

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

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

Stop the engine immediately if anyone falls overboard.

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

Exhaust contains poisonous carbon monoxide which can’ cause unconsciousness and may lead to death. Never run the outboard in a closed garage or confined area.

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 tank

cap is closed properly and securely.

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.

It is your responsibility to choose a boat suitable for the engine (5 horsepower).

manufacturer’s power recommendation. Damage and injury may result.

1. Installation Position

Do not exceed the boat

Install at the stern at the center line of the boat.

2. Installation Height

For proper propeller depth and engine

cooling, the boat’s transom height must match the motor’s shaft length. The short shaft motor requires a transom height of about 15 in. The long shaft motor requires a transom height of about 20 in. Once the boat is in the water and loaded, check proper motor depth by looking at the anti-cavitation plate: with the motor not running, the plate should be about 100 mm (4 in.) below the surface of the water.

,During operation, check to be sure the anticavitation plate remains under

water at all times and that water flows from the water check hole.

Excessive or imbalanced loading will affect the motor’s water depth.

Loading too far forward will raise the motor out of the water, reducing engine cooling. Loading too much or too far rearward will push the motor deeper, reducing pe’rformance.

ANTI-CAVITATION, PLATE

CAUTION: Insufficient water supply (anticavitation plate out of the j water) may cause overheating that will damage the outboard motor.

3. Motor Attachment

Attach the stern bracket to the transom and tighten the clamp screws.

CAUTION: . . While operating the boat, check

the tightness of the clamp screws occasionally.

Tie a rope through the hole in the stern bracket and secure the other end of the rope to the boat. This will prevent accidental loss of the motor.

4. Motor Angle (cruising)

Adjust the motor so the axis of the propeller is parallel with the water surface.

5. Motor Angle Adjustment

If the propeller axis is not parallel with the water surface, adjust by changing the adjusting rod position. There are four adjusting stages.

1. Push the adjusting rod in (A), twist upwards in (B) and pull out to remove.

2. Inserting the rod in the proper hole, twist it down to lock.

CAUTION: To prevent damage to

4. PRE-OPERATIION CHECKS

1. Check the engine oil level.

CAUTION:

Engine oil is a major factor affecting, engine performance and service life. Nondetergent and low quality oils are not recommended, because they have inadequate lubricating properties.

Running the engine with insufficient oil can cause serious engine damage.

Use Honda 4-stroke oil or an

equivalent high detergent, premium

quality motor oil certified to meet or

exceed U.S. automobile manufac-

turers requirements for Service

Classification SF CC/CD or SG. Motor oils classified SF CC/CD or SG _ will show this designation on the -jo -20 -IO i lb

container.

SAE low-30 is recommended for general, all-temperature use. Other viscosities shown in the chart may be used when the average temperature in your area is within the indicated range.

Position the outboard motor vertically, and remove the engine cover.

Remove the dipstick and wipe with a clean rag.

Reinsert the dipstick, and check the oil level with the dipstick resting on the filler opening (do not screw in). If the oil level is low, fill to the upper level mark.

2. Fuel Level

Check the fuel gauge and refill the tank if the fuel level is low. NOTE: Open the vent knob before removing the fuel filler cap. When the

vent knob is firmly closed, the cap will be difficult to remove. Your engine is designed to use any gasoline that has a pump oc-

tane number (y

) of 86 or higher, or that has a research octane number

of 91 or higher. Gasoline pumps at service stations normally display the

pump octane number. We recommend that you use unleaded fuel because it produces fewer engine and spark plug deposits and extends the life of exhaust system

components.

Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid

getting dirt, dust or water in the fuel tank. Use of a lower octane gasoline

can cause persistent “pinging” or heavy “spark knock” (a metallic rapp-

ing noise) which, if severe, can lead to engine damage.

CAUTION: If “spark knock” or “pinging” occurs at a steady engine speed under normal load, change brands of gasoline. If spark knock or

pinging persists, ‘consult your authorized Honda dealer. Failure to do so is

considered misuse, and damage caused by misuse is not covered by

Honda’s Limited Warranty.

Occasionally, you may experience light spark knock while operating under

heavy loads. This is no cause for concern, it simply means your engine is

operating efficiently.

where gasoline is stored.

Do not overfill the tank (there should be no fuel in the filler neck). After refueling, make sure the tank cap is closed properly and securely. Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make sure the area is dry before starting the engine.

Avoid repeated or prolonged contact with skin or breathing of vapor.

KEEP OUT OF REACH OF CHILDREN.

GASOLINES CONTAINING ALCOHOL

you decide

to use a gasoline containing alcohol (gasohol), be sure its octane rating is at least as high as that recommended by Honda. There are two types of “gasohol”:

one containing ethanol, and the other containing methanol. Do not use gasohol that contains more than 10% ethanol. Do not use gasoline containing methanol (methyl or wood alcohol) that does not also contain cosolvents and corrosion inhibitors for methanol. Never

use gasoline containing more than 5% methanol, even if it has cosolvents

and corrosion inhibitors. NOTE:

Fuel system damage or engine performance problems resulting from the

use of fuels that contain alcohol is not covered under the warranty.

Honda cannot endorse the use of fuels containing methanol since

evidence of their suitability is as yet incomplete.

Before buying fuel from an unfamiliar station, try to find out if the fuel contains ‘alcohol; if it does, confirm the type and percentage of alcohol used. If you notice any undesirable operating symptoms while,using a gasoline that contains alcohol, or one that you think contains alcohol, switch to a gasoline that you know does not contain alcohol.

3. Check the following items.

Check the propeller, the shear pin, and the cotter pin to be sure they are secure and undamaged.

Check the stern bracket to be sure the motor is securely installed.

Check steering handle operation.

Make sure you have the tool kit and spare parts with you (p. 26).

The anode metal for damage, looseness or excessive corrosion.

The anode metal helps to protect the outboard motor form corrosion damage; it must be exposed directly to the water whenever the motor is in

use. Replace the anode metal when it has been reduced to approximately

one half of its original size.

CAUTION: The possibility of corrosion damage is increased if the anode

metal is painted over or allowed to deteriorate.

5. STARTING THE ENGINE

Fuel Line Connection CAUTION: To prevent damage to the outboard from overheating, never

run the engine with the propeller out of the water.

1. Connect the fuel line to the tank and outboard motor, as shown. Be sure the connectors are securely latched.

NOTE:

Position the fuel tank so the tank fuel line connector is no more than 1 meter (3.3 ft) below the motor fuel line connector.

Do.not place the fuel tank more than 2 meters (6.6 ft) away from the motor.

Be sure that the fuel line is not kinked:
