When the green light is lit, oilpressure is OK.
If the engine overheats, the red lightwill come on, and the engineprotection system will limit enginespeed.
Remote controls are also equippedwith a buzzer that sounds when thered light comes on.
Engine overheating may be the resultof clogged water intakes.
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.
Remote controls are also equippedwith a buzzer that sounds when thegreen light goes off.The buzzing sound stops below anengine speed of 1,400 rpm.

CONTROLS AND FEATURES
COOLING SYSTEM INDICATOR ANODES (each side)
ANODE(G and T types only)
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 engine is equipped with anoverrev limiter to prevent thepossibility of mechanical damagefrom excessive engine speed.
The overrev limiter may be activatedduring operation, limiting enginespeed, if the outboard motor is tiltedexcessively, or when propellerventilation occurs during a sharp turn.
If the overrev limiter is activated,check the trim angle of the outboardmotor.

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.
You may further secure the outboardmotor by bolting the stern bracket tothe boat transom. Use the optionalmounting bolt and nut kit or othergood quality stainless steel bolts, nuts,and washers. Apply silicone sealantto the bolt holes.

The outboard motor’s 12-volt outputis intended for battery charging only.Lights and electrical accessories forthe boat should be connected to thebattery.
The battery should be kept in acorrosion-resistant battery box that issecurely mounted in a location awayfrom the fuel tank and protectedfrom water and direct sunlight.
These types are equipped withbattery cables. The positive (+) cablehas a red band at the batteryconnector. The negative (-) cable hasa black band at the battery connector.
These types are equipped with a 12-volt DC battery-charging receptaclewhich can be wired to a 12-voltbattery to power lights and electricalaccessories for the boat.
Honda BF15D/BFP15D/BF20D andBFP20D outboard motors produce a12-volt, 12-ampere battery-chargingcurrent and are equipped forconnection to a 12-volt battery. Thebattery-charging circuit is protectedby a 20-ampere fuse located in theengine compartment.
Use the transom angle adjustment rod(p. ) to adjust the angle of theoutboard motor so the propeller isperpendicular to the surface of thewater.
For electric starter operation, use a12-volt battery with an ampere-hourrating of at least 35 Ah (27 CCA).

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.

Trim (except T type)
OPERATION
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.
If engine speed becomes unstable athigh speed due to activation of theoverrev limiter, reduce speed andcheck the trim angle of the outboardmotor.For best fuel economy, limit the
throttle opening to 80%. Use thethrottle friction control (p. orp. ) to help you hold a steadyspeed.
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.

Adding a Fuel Stabilizer
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.
You can extend fuel storage life byadding a gasoline stabilizer that isformulated for that purpose, or youcan avoid fuel deterioration problemsby draining all the fuel from the fueltank and carburetor.
When adding a fuel stabilizer, fill thefuel tank with fresh gasoline. If onlypartially filled, air in the tank willpromote fuel deterioration duringstorage. If you keep an additionalcontainer of gasoline for refueling,be sure that it contains only freshgasoline.
Add fuel stabilizer following themanufacturer’s instructions.
After adding a fuel stabilizer, runthe engine in water for 10 minutesto be sure that the treated gasolinehas replaced the untreated gasolinein the carburetor.

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

TAKING CARE OF UNEXPECTED PROBLEMS
(tiller handle type)
(GREEN)OIL PRESSURE(GREEN)
(remote control type)
Low oil pressure may be the result ofa low engine oil level, or there maybe a problem with the enginelubrication system.
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.
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 or control leveroperation.
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.
Remote-control types are equippedwith a buzzer that sounds when thegreen indicator light goes off.The sound stops below the enginespeed 1,400 rpm.
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 automatically.

Remote-control types are equippedwith a buzzer that sounds when thered indicator light comes on.
Engine overheating may be the resultof clogged water intake screens, orthere may be a problem with thecooling system thermostat or waterpump.
If the engine is stopped after runningat full throttle, and then restartedsoon afterward, that could activatethe engine protection systemmomentarily.
If overheating activates the engineprotection system, idle the engine inneutral, and check the cooling systemindicator.
If water is flowing from the coolingsystem indicator, continue idling for30 seconds. If the cooling system isOK, the red indicator light should gooff within 30 seconds, and the enginewill respond normally to throttle gripor control lever operation.
If there is no water flowing fromthe cooling system indicator, stopthe engine, and tilt the outboardmotor to inspect the water intakescreens. If clogged, clean the waterintake screens, return the outboardmotor to the running position,restart the engine, and check thecooling system indicator again.
If there is still no water flowingfrom the cooling system indicator,or 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.

Carburetor Modification forHigh Altitude Operation
TECHNICAL AND CONSUMER INFORMATION
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.

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