FUEL AND OIL
GASOLINE
Suzuki highly recommends that you use alco-
hol-free unleaded gasoline whenever possible,
with a minimum pump octane rating of 87
((R+M)/2 method). In some areas, the only
fuels that are available are oxygenated fuels.
Oxygenated fuels which meet the minimum
octane requirement and the requirements
described below may be used in your outboard
motor without jeopardizing the New Outboard
Motor Limited Warranty.
NOTE:
Oxygenated fuels are fuels which contain oxy-
gen-carrying additives such as MTBE or alco-
hol.
Gasoline Containing MTBE
Unleaded gasoline containing MTBE (Methyl
Tertiary Butyl Ether) may be used in your out-
board motor if the MTBE content is not greater
than 15%. This oxygenated fuel does not con-
tain alcohol.
Gasoline/Ethanol Blends
Blends of unleaded gasoline and ethanol (grain
alcohol), also known as gasohol, may be used
in your outboard motor if the ethanol content is
not greater than 10%.
NOTICE
Use of leaded gasoline can cause engine
damage. Use of improper or poor quality
fuel can affect performance and may
damage your motor and fuel system.
Use only unleaded gasoline. Do not use
fuel having lower than the recommended
octane, or fuel that may be stale or con-
taminated by dirt/water etc.
Gasoline/Methanol Blends
Avoid using blends of unleaded gasoline and
methanol (wood alcohol) whenever possible.
DO NOT USE fuels containing more than 5%
methanol under any circumstances. Fuel sys-
tem damage or outboard motor performance
problems resulting from the use of such fuels
are not the responsibility of Suzuki and may not
be covered under the New Outboard Motor Lim-
ited Warranty.
Fuel containing 5% or less methanol may be
suitable for use in your outboard motor if they
contain cosolvents and corrosion inhibitors.
Fuel Pump Labeling
In some states, pumps that dispense oxygen-
ated fuels are required to be labeled for the type
and percentage of oxygenate, and whether
important additives are present. Such labels
may provide enough information for you to
determine if a particular blend of fuel meets the
requirements listed above. In other states,
pumps may not be clearly labeled as to the con-
tent or type of oxygenate and additives. If you
are not sure that the fuel you intend to use
meets these requirements, check with the ser-
vice station operator or the fuel suppliers.
NOTE:
Be sure that any oxygenated fuel blend you
use has octane ratings of at least 87 pump
octane ((R+M)/2 method).
If you are not satisfied with the driveability or
fuel economy of your outboard motor when
you are using a gasoline/alcohol blend, you
should switch back to unleaded gasoline con-
taining no alcohol.
If engine pinging is experienced, substitute
another brand, as there are differences
between brands.
NOTICE
Gasoline kept in the fuel tank for long
periods of time will produce varnish and
gum, which can damage the engine.
Always use fresh gasoline.

FILLING THE FUEL TANK
To fill the fuel tank:
1. Always stop the engine before refilling the
tank.
2. Remove the portable fuel tank from the boat
to refill it.
3. Turn the air-vent screw 1 on top of the fuel
tank cap 2 fully counterclockwise to open
the vent.
NOTE:
VENT SCREW should be CLOSED for trans-
portation and OPEN for OPERATlON and CAP
REMOVAL.
WARNING
Gasoline is extremely flammable and
toxic. It can cause a fire and can be haz-
ardous to people and pets.
Always take the following precautions
when refueling:
Never permit anyone other than an
adult to refill the fuel tank.
If you use a portable fuel tank, always
stop the motor and remove the fuel
tank from the boat to refill it.
Do not fill the fuel tank all the way to
the top or fuel may overflow when it
expands due to heating by the sun.
Be careful not to spill fuel. If you do,
wipe it up immediately.
Do not smoke, and keep away from
open flames and sparks.
NOTICE
Fuels containing alcohol can cause paint
damage, which is not covered under the
New Outboard Motor Limited Warranty.
Be careful not to spill fuel containing
alcohol while refueling. If fuel is spilled,
wipe it up immediately.
4. Locate the pressure relief tab 3 under the
fuel tank cap and turn the cap counterclock-
wise until the tab engages the first lock.
5. Press down on the tab, and release the lock,
then rotate the fuel tank cap 1/4 turn. The
tab will engage the second lock.
6. Press the tab down again and turn to
remove the fuel tank cap.
7. Carefully refill the fuel tank with gasoline.
Do not over fill.
8. Tighten the fuel tank cap until an audible
“click” is heard.

MOTOR INSTALLATION
NOTE:
It is against federal regulations for any marine
dealer to service a motor that exceeds the rec-
ommended maximum horsepower for your
boat.
TILLER HANDLE MODEL
Proper transom height is important for good
performance. A motor mounted on a transom
that is too high causes the propeller to slip
resulting in wasted power or overheating.
A motor mounted on a transom that is too low
will increase drag, causing reduced speed.
Make sure that when the motor is lowered all
the way down, the anti-cavitation plate is
located 0 – 25 mm (0 – 1.0 in.) below the bot-
tom of the boat (See illustration below).
WARNING
Overpowering your boat can be hazard-
ous. Excessive horsepower will have an
adverse effect on hull safety and may
cause operating/handling difficulties. The
boat may also sustain stress and hull
damage.
Never install an outboard motor with
horsepower exceeding the manufac-
turer’s recommended maximum horse-
power listed on the boat’s “Certification
Plate”. Contact your authorized Suzuki
marine dealer if you are unable to locate
the hull “Certificate Plate”.
NOTICE
Operating your outboard motor with the
anti-cavitation plate above water can
cause overheating and severe damage to
your outboard motor.
Do not operate your outboard motor with
the anti-cavitation plate above water.
Center the motor on the transom and secure it
by alternately tightening the clamp bracket
screws by hand. Make sure you accurately cen-
ter the motor, or the boat will pull to one side
during operation.
Install 10 mm bolts, washers and nuts, as illus-
trated and tighten the bolts sequentially. Be
sure to seal the holes to prevent water leakage.

After installing the motor, check to make sure
that steering and tilt movement are not
obstructed by any part of the boat. Also make
sure that the battery cable (if applicable)
doesn’t interfere with movement of the motor.
WARNING
If the motor is not properly secured to the
transom, it can come off.
Be sure to bolt the motor to the transom.
The motor may come off if it is held only
by the clamp screws. Occasionally check
the clamp screws for tightness.
NOTICE
If you attempt to mount the outboard to
the transom without having mechanical
experience or without being certain
where to drill holes, you can seriously
damage the boat.
If you do not have mechanical experience
or are not sure of where to drill holes in
the boat’s transom, you should have your
motor mounted by your authorized
Suzuki marine dealer.
REMOTE CONTROL MODEL
Suzuki strongly recommends that you have
your outboard motor, controls and gauges
installed by your authorized Suzuki Marine
Dealer. He has the tools, the facilities and the
know-how to do the job correctly.
WARNING
Failure to have your outboard motor and
associated controls and gauges properly
installed can result in personal injury or
damage.
Suzuki strongly recommends that you

BATTERY INSTALLATION
BATTERY REQUIREMENT
Choose a 12 Volt cranking-type lead acid bat-
tery that meets the specifications shown below.
450 Marine Cranking Amps (MCA)/ABYC,
or 330 Cold Cranking Amps (CCA)/SAE
or 70 Reserve Capacity (RC) Minutes/SAE
NOTE:
The specifications listed above are the mini-
mum battery rating requirements for starting
the engine.
Additional electrical loads from the boat will
require larger capacity batteries. Consult
your Suzuki dealer to determine the proper
battery sizing for your boat and engine com-
bination.
Dual-purpose (Cranking/Deep-cycle) batter-
ies can be used if they meet the minimum
specifications listed above (MCA, CCA, or
RC).
Do not use a Deep Cycle battery for the main
cranking battery.
The use of Maintenance-Free, sealed, or Gel-
Cell batteries is not recommended because
they may not be compatible with Suzuki’s
charging system.
When connecting batteries in parallel, they
must be of the same type, capacity, manufac-
turer, and of similar age. When replacement
is necessary, they should be replaced as a
set. Consult your Suzuki dealer for proper
battery installation information.
BATTERY INSTALLATION
Secure the battery in a dry area of the boat,
away from vibration.
NOTE:
It is recommended that the battery be
installed in an enclosed battery case.
When connecting batteries, hexagon-nuts
must be used to secure battery leads to bat-
tery posts.
To hook up the battery, first connect the red
lead from the motor to the positive battery ter-
minal, then connect the black lead to the nega-
tive battery terminal.

To remove the battery, first disconnect the black
lead from the negative terminal, then discon-
nect the red lead from the positive terminal.
Connecting and disconnecting the battery as
described above will help minimize the chance
of creating an accidental short circuit and
sparks.
WARNING
If you place the battery near the fuel tank,
a spark from the battery may ignite the
gasoline, causing a fire and/or an explo-
sion.
Do not place the fuel tank in the same
compartment/area as the battery.
WARNING
Batteries produce flammable hydrogen
gas and may explode if they are near
flames or sparks.
Never smoke or cause sparks when work-
ing near the battery. Keep the battery
away from open flames. To avoid creating
a spark when charging the battery, con-
nect the battery charger cables to the
proper terminals before turning the
charger on.
WARNING
Battery acid is poisonous and corrosive.
It can cause severe injury and can dam-
age painted surfaces.
Avoid contact with eyes, skin, clothing,
and painted surfaces. If battery acid
comes in contact with any of these, flush
immediately with large amounts of water.
If acid contacts the eyes or skin, get
immediate medical attention.
NOTICE
The electrical system or its components
may be damaged if proper battery pre-
cautions are not followed.
Be sure to attach battery leads cor-
rectly.
Do not disconnect battery leads from
the battery while the engine is running.
17
USE OF ELECTRICAL ACCESSORIES
To use electrical accessories, you must pur-
chase a 40 AH or larger battery, rectifier and
related items. (Recoil starter model only).
The amount of power (12V DC) available for
accessories depends on the operating condi-
tion of the motor. For getting a detailed informa-
tion, please contact your authorized Suzuki
Marine Dealer.
NOTE:
Use of too much power for electrical accesso-
ries under certain operating conditions can
cause the battery to discharge.
NOTE:
On models equipped with a charge connector,
detach the charge cord from the connector and
install the cap to prevent water entry when not
in use.
NOTICE
If you connect electrical accessories
directly to the power receptacle of the
motor, the electrical accessories could be
damaged.
Connect lights and electrical accessories
for the boat to the battery. Consult your
authorized Suzuki marine dealer for infor-
mation about correct wiring.
PROPELLER SELECTION
AND INSTALLATION
PROPELLER SELECTION
It is essential to use a propeller on your out-
board motor that is properly matched to your
boat’s operating characteristics. The speed of
the engine when you operate your boat at full
throttle depends on the propeller you use.
Excessive engine speed can seriously damage
the motor, while low engine speed at full throttle
will adversely affect performance. Your operat-
ing load will also affect propeller selection.
Smaller loads generally require larger-pitch pro-
pellers; larger loads generally require smaller-
pitch propellers. Your authorized Suzuki Marine
Dealer will assist you in selecting a suitable pro-
peller for your boat.
You can determine if your propeller is appropri-
ate for use with your boat by using a tachome-
ter to measure engine speed when operating
your boat at full throttle, under minimum load
conditions. If you are using an appropriate pro-
peller, the engine speed will be within the fol-
lowing range:
If the engine speed is not within this range, con-
sult your authorized Suzuki Marine Dealer to
determine which propeller size is best for you.
If you change propellers, be sure to perform the
above check again, to confirm that the engine
speed under full throttle is within the specified
range.
NOTICE
Installing a propeller with either too much
or too little pitch will cause incorrect
maximum engine speed, which may
result in severe damage to the motor.
Ask your authorized Suzuki marine
dealer to assist you in selecting a suit-
able propeller for your boat.

PROPELLER INSTALLATION
To install a propeller on your outboard motor,
use the following procedure:
1. Coat the propeller shaft splines 1 liberally
with Suzuki water resistant grease to help
prevent corrosion.
2. Place the stopper 2 on the shaft.
3. Align the propeller 3 with the propeller shaft
splines and slide the propeller onto the shaft.
4. Place the spacer 4 and washer 5 on the
shaft.
5. Install the propeller nut 6 and tighten it with
a torque wrench to 29 – 31 N·m (2.9 – 3.1
kg-m/21.0 – 22.5 lb-ft).
6. Align the grooves in the propeller nut with
the hole in the shaft, then insert the cotter
pin 7 and bend the pin ends over to lock it in
place.
To remove the propeller, reverse the above pro-
cedure.
WARNING
Failure to take proper precautions when
installing or removing the propeller can
result in severe personal injury.
When installing or removing the propeller:
Always shift into “Neutral” and remove
the emergency stop switch lock plate
so that the motor cannot be started
accidentally.
Wear gloves to protect hands, and
“lock” the propeller by placing a block
of wood between the blades and the
anti-cavitation plate.
ADJUSTMENTS
TRIM ANGLE ADJUSTMENT
To help maintain steering stability and good
performance, always maintain the proper trim
angle as shown in the illustration. The appropri-
ate trim angle varies depending on the combi-
nation of the boat, engine, and propeller, as well
as operating conditions.
Trim angle too large (Boat tends to “porpoise”)
Trim angle too small (Boat tends to “plow”)
