IMPORTANT SAFETYINFORMATION

BEFORE OPERATION.

To safely realize the full potential ofthis outboard motor, you need acomplete understanding of itsoperation and a certain amount ofpractice with its controls.

Before operating the outboard motorfor the first time, please review the

on page and thechapter titled

For your safety, avoid starting oroperating the engine in an enclosedarea. Your engine’s exhaust containspoisonous carbon monoxide gaswhich can collect rapidly in anenclosed area and cause illness ordeath.

Proper break-in operation allows themoving parts to wear in smoothly forbest performance and long servicelife.

Run the engine at trolling speed. Usethe minimum throttle openingnecessary to operate the boat at a safetrolling speed.

Run the engine up to a maximum of2,000 to 3,000 rpm, which is about10% to 30% of maximum throttleopening.

Run the engine up to a maximum of4,000 to 5,000 rpm, which is about50% to 80% of maximum throttleopening.

Short full-throttle bursts are OK, butdo not operate the enginecontinuously at full throttle.

For boats that plane easily, bring theboat up on plane, and then reduce thethrottle opening to the recommendedrpm range.

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

CRUISING

Engine Speed

Trim

OPERATION

LH TypeLHT, LRT and XRT Types

If engine speed becomes unstable athigh speed due to activation of theoverrev limiter, reduce speed andcheck the trim angle of the outboardmotor.

If, for example, the outboard motoris tilted excessively, or propellerventilation occurs during a sharp turn,the engine may overrev, activatingthe overrev limiter.

The engine is equipped with anoverrev limiter to prevent thepossibility of mechanical damagefrom excessive engine speed.

For rough water conditions or largewaves, slow down to prevent thepropeller from rising out of the water.

Install the outboard motor at the besttrim angle for stable cruising andmaximum power.

Trim angle too large: Incorrectcauses boat to ‘‘squat’’.

Trim angle too small: Incorrectcauses boat to ‘‘plow’’.

For best fuel economy, limit thethrottle opening to 80%. Use thethrottle friction control (p. and

) to help you hold a steady speed.

It is necessary to trim the angle of theoutboard motor to compensate forchanges in boat load, weightdistribution, water conditions, orpropeller selection.

Under normal conditions, the boatwill perform best when the

antiventilation plate is level with thewater.

When cruising into a high wind, trimthe outboard motor down slightly tolevel the boat and improve stability.With a tail wind, trim the outboardmotor up slightly.

Press the UP or DN (down) side ofthe switch to adjust the angle of theoutboard motor.

You can use the power trim/tiltswitch at any time, whether the boatis under way or stopped.

Use the power trim/tilt switch to trimthe outboard motor for the bestperformance and stability.

Refer to the trim meter (p. ) for anindication of whether the motor istrimmed high or low.

FUEL RECOMMENDATIONS

Use unleaded gasoline with a pumpoctane rating of 86 or higher.


Running the engine with persistentspark knock or pinging can causeengine damage.

Distributor’s LimitedWarranty

Your outboard motor is certified tooperate on unleaded gasoline.Unleaded gasoline produces fewerengine and spark plug deposits andextends exhaust system life.

Never use stale or contaminatedgasoline or an oil/gasoline mixture.Avoid getting dirt or water in the fueltank.

Occasionally you may hear a light‘‘spark knock’’ or ‘‘pinging’’(metallic rapping noise) whileoperating under heavy loads. This isno cause for concern.

If spark knock or pinging occurs at asteady engine speed, under normalload, change brands of gasoline. Ifspark knock or pinging persists, seean authorized Honda marine dealer.

Running the engine with persistentspark knock or pinging is misuse,and the

DRAIN SCREW

Distributor’s Limited Warranty

Gasoline will oxidize and deterioratein storage. Old gasoline will causehard starting, and it leaves gumdeposits that clog the fuel system. Ifthe gasoline in your fuel tank andcarburetor deteriorates during storage,you may need to have the carburetorand other fuel system componentsserviced or replaced.

The length of time that gasoline canbe left in your fuel tank andcarburetor without causing functionalproblems will vary with such factorsas gasoline blend, your storagetemperatures, and whether the fueltank is partially or completely filled.The air in a partially filled fuel tankpromotes fuel deterioration. Verywarm storage temperatures acceleratefuel deterioration. Fuel deteriorationproblems may occur within a fewmonths, or even less if the gasolinewas not fresh when you filled thefuel tank.

Thedoes not cover fuel system damageor engine performance problemsresulting from neglected storagepreparation.

You can avoid fuel deteriorationproblems by draining the fuel tankand carburetors.

OUTBOARD MOTOR STAND

CASE PROTECTORS

BEFOREOPERATION

Select a well-ventilated storage area.If possible, avoid storage areas withhigh humidity.

If storing a container of gasoline,such as the portable fuel tank(optional equipment), store it awayfrom any appliance that operates witha flame, such as a furnace, waterheater, or clothes dryer. Also avoidany area with a spark producingelectric motor, or where power toolsare operated.

If the outboard motor will beremoved from the boat for storage,we recommend storing it verticallyby mounting it on a stand.

Cover the outboard motor to keep outdust. Do not use sheet plastic as adust cover. A nonporous cover willtrap moisture, promoting rust andcorrosion.

Check your outboard motor asdescribed in the

chapter of this manual.

If the cylinders were coated with oilduring storage preparation, theengine may smoke briefly at startup.This is normal.

If it is necessary to store the outboardmotor horizontally, drain thecarburetor (p. ), and drain theengine oil (p. ), before removingthe outboard motor from the boat.

Position the outboard motor with itscarburetor side down, and cushion itwith protective packing material.

Carburetor Modification forHigh Altitude Operation

Battery

Minimum Requirements


When the carburetors have beenmodif ied f or high altitude operation,the air-f uel mixture will be too leanf or low altitude use. Operation ataltitudes below 5,000 f eet (1,500meters) with modif ied carburetorsmay cause the engine to overheatand result in serious engine damage.For use at low altitudes, have anauthorized Honda Marine dealerreturn the carburetors to originalf actory specif ications.

At high altitude, the standardcarburetor air-fuel mixture will betoo rich. Performance will decrease,and fuel consumption will increase.A very rich mixture will also foul thespark plugs and cause hard starting.

High altitude performance can beimproved by specific modificationsto the carburetors. If you alwaysoperate your outboard motor ataltitudes above 5,000 feet (1,500meters), have an authorized Hondamarine dealer perform this carburetormodification.

Even with carburetor modification,engine horsepower will decreaseabout 3.5% for each 1,000-foot (300-meter) increase in altitude. The effectof altitude on horsepower will begreater than this if no carburetormodification is made.

For complete information, refer tothe battery manufacturer’sinstructions.

Oxygenated Fuels

ETHANOL:

MTBE:

METHANOL:


Some conventional gasolines arebeing blended with alcohol or anether compound. These gasolines arecollectively referred to as oxygenatedfuels. To meet clean air standards,some areas of the United States andCanada use oxygenated fuels to helpreduce emissions.

If you use an oxygenated fuel, besure it is unleaded and meets theminimum octane rating requirement.

Before using an oxygenated fuel, tryto confirm the fuel’s contents. Somestates/provinces require thisinformation to be posted on the pump.

The following are the EPA-approvedpercentages of oxygenates:

ethyl or grain alcohol;10% by volume.

You may use gasoline containing upto 10% ethanol by volume. Gasolinecontaining ethanol may be marketedunder the name ‘‘Gasohol’’.

Methyl Tertiary Butyl Ether;15% by volume.

You may use gasoline containing upto 15% MTBE by volume.

methyl or woodalcohol; 5% by volume.

You may use gasoline containing upto 5% methanol by volume, as longas it also contains cosolvents andcorrosion inhibitors to protect thefuel system. Gasoline containingmore than 5% methanol by volumemay cause starting and/orperformance problems. It may also

damage metal, rubber, and plasticparts of your fuel system.

If you notice any undesirableoperating symptoms, try anotherservice station, or switch to anotherbrand of gasoline.

Fuel system damage or performanceproblems resulting from the use of anoxygenated fuel containing morethan the percentages of oxygenatesmentioned above are not coveredunder warranty.

Emission Control SystemInformation


Source of Emissions

Tampering and AlteringThe U.S. and Calif ornia CleanAir Acts

The combustion process producescarbon monoxide, oxides of nitrogen,and hydrocarbons. Control ofhydrocarbons and oxides of nitrogenis very important because, undercertain conditions, they react to formphotochemical smog when subjectedto sunlight. Carbon monoxide doesnot react in the same way, but it istoxic.

Honda utilizes lean carburetorsettings and other systems to reducethe emissions of carbon monoxide,oxides of nitrogen, and hydrocarbons.

Tampering with or altering theemission control system may increaseemissions beyond the legal limit.Among those acts that constitutetampering are:

Removal or alteration of any partof the intake, fuel, or exhaustsystems.

Alterations that would cause theengine to operate outside its designparameters.

EPA and California regulationsrequire all manufacturers to furnishwritten instructions describing theoperation and maintenance ofemission control systems.

The following instructions andprocedures must be followed in orderto keep the emissions from yourHonda engine within the emissionstandards.

Maintenance

Replacement PartsProblems That May Af f ectEmissions

A manufacturer of an aftermarketpart assumes the responsibility thatthe part will not adversely affectemission performance. Themanufacturer or rebuilder of the partmust certify that use of the part willnot result in a failure of the engine tocomply with emission regulations.

Follow the maintenance schedule onp. . Remember that this scheduleis based on the assumption that yourmachine will be used for its designedpurpose. Sustained high-loadoperation, or use in unusualconditions, will require morefrequent service.

If you are aware of any of thefollowing symptoms, have yourengine inspected and repaired byyour servicing dealer.

Hard starting or stalling afterstarting.

Rough idle.

Misfiring or backfiring under load.

Afterburning (backfiring).

Black exhaust smoke or high fuelconsumption.

The emission control systems onyour Honda engine were designed,built, and certified to conform withEPA and California emissionregulations. We recommend the useof genuine Honda parts wheneveryou have maintenance done. Theseoriginal-design replacement parts aremanufactured to the same standardsas the original parts, so you can beconfident of their performance. Theuse of replacement parts that are notof the original design and qualitymay impair the effectiveness of youremission control system.
