IMPORTANT SAFETYINFORMATION

Operator Responsibility

OUTBOARD MOTOR SAFETY

Most accidents can be prevented ifyou follow all instructions in thismanual and on the outboard motor.The most common hazards arediscussed below, along with the bestway to protect yourself and others.

It is the operator’s responsibility toprovide the necessary safeguardsto protect people and property.Know how to stop the enginequickly in case of emergency.Understand the use of all controls.

Attach the emergency stop switchlanyard securely to the operator.

Stop the engine immediately ifanyone falls overboard, and do notrun the engine while the boat isnear anyone in the water.

Always stop the engine if youmust leave the controls for anyreason.

Always wear a PFD (PersonalFlotation Device) while on theboat.

Familiarize yourself with all lawsand regulations relating to boatingand the use of outboard motors.

Be sure that anyone who operatesthe outboard motor receives properinstruction.

Be sure the outboard motor isproperly mounted on the boat.

Do not remove the engine coverwhile the engine is running.

Honda BF25D and BF30D outboardmotors are designed for use withboats that have a suitablemanufacturer’s powerrecommendation. Other uses canresult in injury to the operator ordamage to the outboard motor andother property.

Carbon Monoxide HazardRefuel With Care


Exhaust gas contains poisonouscarbon monoxide. Avoid inhalationof exhaust gas. Never run the enginein a closed garage or confined area.

Gasoline is extremely flammable,and gasoline vapor can explode.Refuel outdoors, in a well-ventilated area, with the enginestopped. Never smoke neargasoline, and keep other flamesand sparks away.

Remove any portable fuel tankfrom the boat for refueling. Keepthe portable fuel tank away fromthe battery or other potential sparksources.

Refuel carefully to avoid spillingfuel. Avoid overfilling the fueltank.

After refueling, tighten the fillercap securely. If any fuel is spilled,make sure the area is dry beforestarting the engine.

Less friction allows the outboardmotor to turn more easily. Morefriction helps to hold steady coursewhile cruising or to prevent theoutboard motor from swinging whiletrailering the boat.

The tilt lever enables the outboardmotor to be raised for shallow wateroperation, beaching, launching, ormooring.

Moving the tilt lever to the TILTposition allows the outboard motor tobe tilted and moving the tilt lever tothe RUN (LOCK) position locks theoutboard motor in the desiredposition. Use the tilt lever totemporarily tilt the outboard motorwhen the boat is operating in shallowwater, or mooring in shallow water.The tilt lever must be in the RUN(LOCK) position before operatingthe outboard motor or the motorcould tilt up when operating inreverse.

To tilt, move the lever to the TILTposition, then raise the outboardmotor until the tilt mechanismengages at 30°, 45°, 75° (p. and

ANODE(time tab)

ANODE(SHG, LHT, SRG, LRG, SRT andLRT types only)

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.

The cooling system indicatordischarge port can also becomeplugged.

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.

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.

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.

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

) to help you hold a steady speed.

Under normal conditions, the boat

will perform best when theantiventilation plate is level with thewater.

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

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

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

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

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.

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

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

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

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

MAINTENANCE SAFETY Safety Precautions

Burns from hot parts.

Injury from moving parts.

Carbon monoxide poisoningfrom engine exhaust.


Some of the most important safetyprecautions follow. However, wecannot warn you of everyconceivable hazard that can arise inperforming maintenance. Only youcan decide whether or not you shouldperform a given task.

Make sure the engine is off beforeyou begin any maintenance orrepairs. This will eliminate severalpotential hazards:

Read the instructions before youbegin, and make sure you have thetools and skills required.

To reduce the possibility of fire orexplosion, be careful whenworking around gasoline. Use onlya nonflammable solvent, notgasoline, to clean parts. Keepcigarettes, sparks, and flames awayfrom all fuel-related parts.

Wear gloves when handling thepropeller to protect your handsfrom sharp edges.Let the engine and exhaust

system cool before touching.

Do not run the engine unlessinstructed to do so.

Be sure there is adequateventilation whenever youoperate the engine.

The trim tab compensates for‘‘torque steer’’ which is a reaction ofthe outboard motor to propellerrotation.

If uncompensated, torque steer wouldmake the outboard motor tend to turnto one side.

When the trim tab is correctlyadjusted, steering effort is equal ineither direction.

If steering effort is unequal, loosenthe trim tab bolt and adjust the angleof the trim tab. Retighten the trim tabbolt securely. If less effort is required to make left

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
