When the green light is lit, oilpressure is OK.
If oil pressure becomes low, thegreen light will go off, and theengine protection system will limitengine speed.
Low oil pressure indicates that theengine oil level is low, or that there isa problem with the engine lubricationsystem.
Water should flow from the coolingsystem indicator while the engine isrunning. This shows that water iscirculating through the coolingsystem.
If water stops flowing while theengine is running, that indicates acooling system problem, such asclogged water intakes, which willcause engine overheating.
The anode is made of a sacrificialmaterial that helps to protect theoutboard motor from corrosion.
There is an anode on theantiventilation plate.

SAFETY ROPE
If the outboard motor is installed toolow, the boat will squat and be hardto plane, it will tend to porpoise, andhigh-speed stability will be reduced.
If the outboard motor is installed toohigh, that will cause ventilation.
Optimum installation height varieswith boat type and bottom shape.Contact the boat manufacturer forany special recommendations that areunique to a specific model of boat.
If the transom needs to be modifiedto accommodate the outboard motor,contact the boat manufacturer andfollow their recommendations forcorrective action.
Attach the stern bracket to the boattransom by tightening the clampscrews.
Attach a rope from the boat to thehole in the stern bracket. This willhelp to prevent accidental loss of theoutboard motor.
Use the transom angle adjustment rod(p. ) to adjust the angle of theoutboard motor so the propeller isperpendicular to the surface of thewater.

O.K.
Excessive trim/tilt angle duringoperation can cause propellerventilation, overheating, and waterpump damage.
For rough water conditions or largewaves, slow down to prevent thepropeller from rising out of the water.
For best fuel economy, limit thethrottle opening to 80%. Use thethrottle friction control (p. ) tohelp you hold a steady speed.
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’’.
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 theantiventilation 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.

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.
Disconnect the fuel hose from theoutboard motor.
With the outboard motor in avertical position, place anapproved gasoline container belowthe fuel drain outlet, and use afunnel to avoid spilling fuel.Loosen the drain screw to drainfuel from the carburetor.

CASE PROTECTOR BEFOREOPERATION
Any other horizontal storage positionmay cause damage or oil leakage.
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 storing horizontally, be sure to foldthe tiller handle, and the outboardmotor rests on its case protectors. Besure all water has drained from theoutboard motor before placing it onits side, so no residual water canenter the engine exhaust port.
Store the outboard motor eithervertically or horizontally with thetiller handle side up.
If the cylinder was coated with oilduring storage preparation, theengine may smoke briefly at startup.This is normal.

OIL PRESSURE INDICATORLIGHT GOES OFF ANDENGINE SPEED IS LIMITED
TAKING CARE OF UNEXPECTED PROBLEMS
OIL PRESSURE INDICATOR LIGHT
If the throttle is closed suddenly afterfull throttle operation, engine speedmay drop below the specified idlerpm, and that could activate theengine protection systemmomentarily.
If low oil pressure activates theengine protection system, stop theengine, check the engine oil level(p. ), and add oil if needed.
If oil pressure becomes low, thegreen indicator light will go off, andthe engine protection system willlimit engine speed. If you are atcruising speed, engine speed willdecrease gradually.
Low oil pressure may be the result ofa low engine oil level, or there maybe a problem with the enginelubrication system.
If the engine protection systemremains activated after 30 seconds,return to the nearest boat landing,and have the outboard motorinspected by an authorized Hondamarine dealer.
With the engine oil at therecommended level, restart theengine. If the lubrication system isOK, the green indicator light shouldcome on within 30 seconds, and theengine will respond normally tothrottle grip operation.

SUBMERGED MOTOR
TAKING CARE OF UNEXPECTED PROBLEMS
A submerged outboard motor mustbe serviced immediately after it isrecovered from the water in order tominimize corrosion.
Remove the engine cover, andrinse the outboard motor withfresh water to remove salt water,sand, mud, etc.
If there is a Honda marine dearshipnearby, take the motor to the dealerimmediately. If you are far from adealership, proceed as follows:
Drain the carburetor as describedon p. .
Change the engine oil as describedon p. . If there was water in theengine crankcase, or if the usedengine oil showed signs of watercontamination, then a secondengine oil change should beperformed after running the enginefor half an hour.
If the engine was running when itsubmerged, there may bemechanical damage, such as a bentconnecting rod. If the engine bindswhen cranked, do not attempt torun the engine until it has beenrepaired.
Remove the spark plug (p. ),and remove the clip from theengine switch. Pull the recoilstarter grip, rotate the flywheel afew revolutions to completelyexpel any water from the cylinder.

Carburetor Modification forHigh Altitude Operation
TECHNICAL AND CONSUMER INFORMATION
When the carburetor 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 carburetormay cause the engine to overheatand result in serious engine damage.For use at low altitudes, have anauthorized Honda Marine dealerreturn the carburetor to originalf actory specif ications.
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.
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 plug and cause hard starting.
High altitude performance can beimproved by specific modificationsto the carburetor. If you alwaysoperate your outboard motor ataltitudes above 5,000 feet (1,500meters), have an authorized Hondamarine dealer perform this carburetormodification.

TECHNICAL AND CONSUMER INFORMATION
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.

Emission Control SystemInformation
TECHNICAL AND CONSUMER INFORMATION
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.
