IDENTIFICATION
NUMBER LOCATION
The model and identification numbers of your
outboard motor are stamped on a plate
attached to the clamp bracket. It is important to
know these numbers when you place a parts
order or if your motor is stolen.
FUEL AND OIL
GASOLINE
Suzuki highly recommends that you use alco-
hol-free unleaded gasoline whenever possible,
with a minimum octane rating of 91 (Research
method). However, blends of unleaded gasoline
and alcohol with equivalent octane content may
be used, provided the guidelines that follow are
met.
NOTE:
Oxygenated fuels are fuels which contain oxy-
gen-carrying additives such as MTBE or alco-
hol.
NOTICE
Use of leaded gasoline can cause engine dam-
age. 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 contaminated by
dirt/water etc.
Suzuki recommends that you install a water-
separating fuel filter assembly between your
boat’s fuel tank(s) and outboard motor(s). Fuel
filtration systems of this type will help prevent
water that may be present in your boat’s fuel
tank(s) from contaminating your motor’s elec-
tronic fuel injection system. Water contamina-
tion can cause poor engine performance and
can also cause damage to the electronic fuel
injection system components.
Your Authorized Suzuki Marine Dealer can pro-
vide you advice about water-separating fuel fil-
ter systems and installation.
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, are commer-
cially available in some areas. Gasoline con-
taining a maximum of 10% ethanol may be
used in your outboard motor without jeopardiz-
ing the New Outboard Motor Limited Warranty.
Gasoline/Methanol Blends
Blends of unleaded gasoline and methanol
(wood alcohol) are also commercially available
in some areas. DO NOT USE fuels containing
more than 5% methanol under any circum-
stances. Fuel system 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 Limited Warranty.
Fuel containing 5% or less methanol may be
suitable for use in your outboard motor if they
contain cosolvents and corrosion inhibitors.

6
Pump Labeling for Gasoline/Alcohol
Blends
In some states, pumps that dispense gasoline/
alcohol blends are required to be labeled for the
type and percentage of alcohol content, 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 alcohol and additives. If you are
not sure that the fuel you intend to use meets
these requirements, check with the service sta-
tion operator or the fuel suppliers.
NOTE:
If you are not satisfied with the operation or fuel
economy of your outboard motor when you are
using gasoline/alcohol blends, you should
switch back to unleaded gasoline containing no
alcohol.
Be sure that any gasoline/alcohol blend you use
has octane ratings of at least 91 octane
(Research method).
If engine pinging is experienced, substitute
another brand as there are differences between
brands.
Unleaded gasoline will extend spark plug life.
 WARNING
Gasoline is extremely flammable and toxic. It
can cause a fire and can be hazardous to peo-
ple 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.
NOTE:
The fuel tank supplied with this motor is its ded-
icated fuel reservoir and should not be used as
a fuel storage container.
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.
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.

7
ENGINE OIL
Oil quality is a major contributor to your
engine’s performance and life. Always select
good quality engine oil.
Suzuki recommends use of a SAE 10W-40
NMMA certified FC-W oil. If NMMA certified
FC-W oil is not available, select a good quality
4-cycle motor oil from the following chart
according to the average temperatures in your
area.
NOTE:
In very cold weather (below 5°C (41°F), use
SAE (or NMMA FC-W) 5W-30 for easier start-
ing and smooth operation.
GEAR OIL
Suzuki recommends the use of SUZUKI OUT-
BOARD MOTOR GEAR OIL. If it is not avail-
able, use SAE 90 hypoid gear oil which is rated
GL-5 under the API classification system.
NOTICE
Use of poor quality engine oil can adversely
affect engine performance and life.
Suzuki recommends that you use Suzuki
Marine 4-Cycle Engine Oil or its equivalent.

BATTERY INSTALLATION
BATTERY REQUIREMENT
Choose a 12 Volt cranking-type lead acid bat-
tery that meets the specifications shown below.
650 Marine Cranking Amps (MCA)/ABYC,
or 512 Cold Cranking Amps (CCA)/SAE
or 160 Reserve Capacity (RC) Minutes/SAE
or 12 Volt, 100 AH
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.

12
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.

tact 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 precautions are
not followed.
• Be sure to attach battery leads correctly.
• Do not disconnect battery leads from the
battery while the engine is running.

13
USE OF ELECTRICAL
ACCESSORIES
The amount of power (DC12V) available for
accessories, however, depends on the operat-
ing condition of the motor. For getting a detailed
information, please inquire of 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.
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 the performance. Your
operating load will also affect propeller selec-
tion. Smaller loads generally require larger-
pitch propellers; larger loads generally require
smaller-pitch propellers. Your authorized Suzuki
Marine Dealer will assist you in selecting a suit-
able propeller 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.
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 suitable propeller for
your boat.

PROPELLER INSTALLATION
To install a propeller on your outboard motor,
use the following procedure:
1. Coat the propeller shaft splines 1liberally
with Suzuki water resistant grease to help
prevent corrosion.
2. Place the stopper 2on the shaft.
3. Align the propeller 3with the propeller shaft
splines and slide the propeller onto the shaft.
4. Place the spacer 4and washer 5on the
shaft.
5. Install the propeller nut 6and tighten it with
a torque wrench to 50 – 60 N·m (5.0 – 6.0
kg-m/36.0 – 43.5 lb-ft).
6. Insert the cotter pin 7and bend it so that it
can’t come off.
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.
ADJUSTMENT
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”)
• Proper trim angle
Trim range
Tilt range

15
 WARNING
Trim angle greatly affects steering stability. If
the trim angle is too small, the boat may
“plow” or “bow steer”. If the trim angle is too
large, the boat may “chine walk” from side to
side or “porpoise” up and down. These condi-
tions, which result in loss of steering control,
can cause occupants to be thrown overboard.
Always maintain proper trim angle based on
the combination of your boat, engine, and pro-
peller, as well as operating conditions.
 WARNING
When the motor is tilted beyond the maximum
trim position, the swivel bracket will not have
side support from the clamp bracket and the
tilt system will be unable to cushion the
engine if the lower unit strikes an obstruction.
This could lead to occupant injury.
Do not operate the engine above 1500 r/min or
operate the boat in a planing attitude with the
motor tilted beyond the maximum trim posi-
tion.
NOTICE
If you operate the boat with the motor trimmed
beyond the maximum trim position, the water
intake holes may be above the water line,
causing severe engine damage due to over-
heating.
Never operate the boat with the motor
trimmed beyond the maximum trim position.
Make a test run in the boat to determine if the
trim angle needs to be adjusted. Adjust the trim
angle using the Power Trim and Tilt system. If
necessary, you can change the limit of down-
ward travel that can be achieved using the
Power Trim and Tilt by moving the tilt pin to
another position.
While operating your boat with the motor
adjusted to the proper trim angle, observe the
position of the needle on the TRIM GAUGE pro-
vided as optional part. When making future trim
angle adjustment, use the TRIM GAUGE as a
guide.
(Optional part)

16
TRIM TAB ADJUSTMENT
This adjustment is used to compensate for the
possible tendency of your boat to veer slightly
to port or starboard. This tendency could be
due to such things as propeller torque, motor
mounting position, etc.
To adjust the trim tab:
1. Loosen the bolt Athat holds the trim tab in
place.
2. If the boat tends to veer to port, move the
rear end of the trim tab toward the port side.
If the boat tends to veer to starboard, move
the starboard side.
3. Tighten the bolt that holds the trim tab in
place.
After adjusting the trim tab, check to see if the
boat still tends to veer to one side. If necessary,
readjust the trim tab.
THROTTLE TENSION ADJUSTMENT
The tension of the remote control handle can be
adjusted according to your preference. To
increase the tension, turn the throttle tension
adjuster Aclockwise. To decrease the tension,
turn the adjuster counterclockwise.
IDLE SPEED ADJUSTMENT
The idle speed has been factory adjusted
between 650 – 750 r/min in neutral.
NOTE:
If idle speed cannot be set within the specified
range, contact your authorized Suzuki Marine
Dealer.
SETTING OF TILT UPPER LIMIT POSITION
If the outboard motor contacts the motor well of
the boat during full tilt up operation, the upper
limit setting should be reset.
Perform this set-up after the current position
setting has been canceled, as explained in the
following procedure.
