CleaningFlushing With the Honda
Water Hose Connector
Af ter each use in saltwater or dirty
water, thoroughly clean and flush the
outboard motor with f resh water.
Wash the outside of the outboard
motor with clean, f resh water to
remove mud, salt, seaweed, etc.
Disengage the emergency stop switch
clip f rom the emergency stop switch,
and pull the recoil starter rope several
times to expel any water remaining in
the water pump.
Tilt up the outboard motor and
move the tilt lever to the TILT
position. Reinstall the f lush screw and the
propeller (p. ). After flushing, stop the engine,
and disconnect the fuel hose from
the outboard motor. Remove the
hose connector, and leave the
outboard motor in the running
position f or one minute to drain
the water from inside the engine. Touch up any damaged paint, and
coat areas that may rust with Honda
Corrosion Inhibitor, or equivalent.
Lubricate controls with a silicone
spray lubricant.Tilt down the outboard motor.
Remove the f lush screw f rom the
WASH screw hole and install the
water hose connector.
Attach a hose f rom a f resh water
f aucet to the water hose connector
of the f lush kit.
Remove the propeller (P. ).

Flushing Without the Honda
Water Hose Connector
Running the engine without good
water circulation can cause
overheating and water pump
damage.
Distributor’s Limited Warranty It is necessary to run the engine
during the flushing procedure. For
safety, remove the propeller from the
outboard motor (p. ).
Damage caused by running the
outboard motor without sufficient
cooling water is not covered by the
(p. ).
Start the engine and run in the N
(neutral) position at low speed f or
at least 10 minutes.
Tilt down the outboard motor.
Place a container under the
outboard motor, and f ill it with
clean, f resh water. The water level
must be at least 2 inches (5 cm)
above the antiventilation plate.After flushing, stop the engine,
and disconnect the fuel hose from
the outboard motor and leave the
outboard motor in the running
position f or one minute to drain
the water from inside the engine.Tilt up the outboard motor and

							61 Fuel
STORAGE
Adding a Fuel Stabilizer
Depending on the region where you
operate your outboard, f uel
f ormulations may deteriorate and
oxidize rapidly. Fuel deterioration
and oxidation can occur in as little
as 15 days and may cause damage to
the carburetor and f uel system.
Please check with your servicing
dealer f or local storage
recommendations.
Distributor’s Limited Warranty Gasoline will oxidize and deteriorate
in storage. Deteriorated gasoline will
cause hard starting, and it leaves gum
deposits that clog the fuel system. If
the gasoline in your fuel tank and
carburetor deteriorates during storage,
you may need to have the carburetor
and other fuel system components
serviced or replaced.You can extend f uel storage lif e by
adding a gasoline stabilizer that is
formulated for that purpose, or you
can avoid f uel deterioration problems
by draining all the fuel from the fuel
tank and carburetor.
The
(p. ) does not cover fuel system
damage or engine performance
problems resulting f rom neglected
storage preparation.When adding a f uel stabilizer, f ill the
f uel tank with f resh gasoline. If only
partially f illed, air in the tank will
promote fuel deterioration during
storage. If you keep an additional
container of gasoline for refueling,
be sure that it contains only fresh
gasoline. The length of time that gasoline can
be left in your fuel tank and
carburetor without causing functional
problems will vary with such factors
as gasoline blend, your storage
temperatures, and whether the f uel
tank is partially or completely f illed.
The air in a partially f illed f uel tank
promotes fuel deterioration. Very
warm storage temperatures accelerate
fuel deterioration. Fuel deterioration
problems may occur in less than 15
days, if the gasoline was not fresh
when you f illed the f uel tank.Add Honda Marine f uel stabilizer
following the instructions on the
label.
Turn the engine OFF. After adding a fuel stabilizer, run
the engine in water for 10 minutes
to be sure that the treated gasoline
has replaced the untreated gasoline
in the carburetor. 2.

							Gasoline is highly
flammable and explosive.
You can be burned or
seriously injured when
handling fuel.
Stop the engine and keep
heat, sparks, and flame
away.
Handle fuel only
outdoors.
Wipe up spills
immediately.

DRAIN PORT
Draining the Fuel SystemAfter the fuel has drained from the
carburetor, tighten the drain screw
securely. With the outboard motor in a
vertical position, place an
approved gasoline container below
the f uel drain outlet, and use a
f unnel to avoid spilling f uel.
Loosen the drain screw to drain
fuel from the carburetor.Reconnect the drain tube to the air
guide. Disconnect the fuel hose from the
outboard motor.
Disconnect the drain tube from the
air guide, then connect it to the
carburetor drain port as shown. You can avoid f uel deterioration
problems by draining the fuel tank
and carburetor.
Drain the f uel tank into an
approved gasoline container, or if
you need to store fuel in the fuel
tank, you can extend fuel storage
lif e by f illing the f uel tank with
fresh gasoline and adding Honda
Marine f uel stabilizer f ollowing
the directions on the container.
Close the fuel cap vent.
If using the portable fuel tank,
close the f uel f iller cap vent knob.
Store the portable fuel tank in a
cool dry place out of direct
sunlight. 4. 3.

63 Engine Oil STORAGE PRECAUTIONS
STORAGE
CARRYING HANDLELif ting the outboard motor by the
engine cover, or using the installed
outboard motor as a handle or lever
to move the boat, can damage the
outboard motor. Select a well-ventilated storage area.
If possible, avoid storage areas with
high humidity.
If your portable fuel tank contains
gasoline, store it away from any
appliance that operates with a f lame,
such as a f urnace, water heater, or
clothes dryer. Also avoid any area
with a spark-producing electric motor,
or where power tools are operated. Change the engine oil (p. ).To carry the outboard motor, hold it
by the carrying handle, or hold by the
carrying handle and the lug beneath
the engine cover lock lever, as shown.
Remove the spark plug (p. ),
and remove the emergency stop
switch clip f rom the emergency
stop switch.
Pour 1 2 teaspoons (5 10 cm )
of clean engine oil into the
cylinder.
Reinstall the spark plug (p. ). Pull the starter grip several times
to distribute the oil in the cylinder. 1.

							64REMOVAL FROM STORAGE
STORAGE
CASE PROTECTORSBEFORE
OPERATION
Any other horizontal storage position
may cause damage to the outboard
motor or oil leakage.Cover the outboard motor to keep out
dust. Do not use plastic sheet as a
dust cover. A nonporous cover will
trap moisture, promoting rust and
corrosion.
Check your outboard motor as
described in the
chapter of this manual.
If storing horizontally, be sure to fold
the tiller handle, and rest the
outboard motor on its case protectors.
Be sure all water has drained f rom
the outboard motor before placing it
on its side, so no residual water can
enter the engine exhaust port. Store the outboard motor either
vertically or horizontally with the
tiller handle side up.If the cylinder was coated with oil
during storage preparation, the
engine may smoke briefly at startup.
This is normal.

TRANSPORTING
CARRYING HANDLE
OUTBOARD MOTOR SUPPORT BAR
(commerciallyavailable)
Lif ting the outboard motor by the
engine cover, or using the
installed outboard motor as a
handle or lever to move the boat,
can damage the outboard motor. Remove the outboard motor from the
boat and secure the outboard motor
in either the vertical or horizontal
position shown on p. .To carry, hold the outboard motor by
the carrying handle, or hold by the
carrying handle and the lug beneath
the engine cover lock latch, as shown. When trailering a boat with the
outboard motor attached, always
disconnect the fuel line from the
portable fuel tank and tighten the
steering f riction bolt securely (p. ).
The pref erred method is to leave the
engine in the normal running position,
but if there is insufficient road
clearance, you can tilt the outboard
motor using a commercially available
outboard motor support bar available
through your dealer. Refer to the
manufacturer’s instructions for using
an outboard motor support bar.3464
