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 alcohol.
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.
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/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%.
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.
• Unleaded gasoline will extend spark plug life.

7
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
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.
ENGINE OIL
Oil quality is a major contributor to your
engine’s performance and life. Always select
good quality engine oil.
Suzuki recommends the use of SAE 10W-40 or
10W-30 SUZUKI MARINE 4-CYCLE ENGINE
OIL. If SUZUKI MARINE 4-CYCLE ENGINE
OIL is not available, select a NMMA certified
FC-W oil or 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
HYPOID GEAR OIL. If it is not available, 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 (ECSTAR) or
its equivalent.

SUZUKI KEYLESS START
SYSTEM
(IF EQUIPPED WITH
KEYLESS START SYSTEM)
This system allows you to start the engine by
means of communication between the key-fob
and the keyless control unit when you have the
key-fob with you, instead of using the mechani-
cal key.
The engine can be started when the distance
between the key-fob and the keyless control
unit is within the communication range of 1 m
(39.4 in.).
In addition, this system is equipped with immo-
bilizer feature.
NOTE:
Please consult with a Suzuki Marine Dealer for
the installation of the Keyless Start System.
Also refer to the “Keyless Start System Instruc-
tion Manual” supplied with the product for
detailed operating instructions.
IMMOBILIZER SYSTEM
In this system, the key-fob and the keyless con-
trol unit uses radio communication to check if
the key-fob ID is registered in the Keyless Start
System.
If the key-fob ID is not registered, the system
prevents the engine from starting using the key-
fob.
Key-fob
Keyless control unit
KEY-FOB
Two (2) key-fobs are supplied with the Keyless
Start System.
WARNING
Radio waves from the keyless control
unit may interfere with the operation of
electrical medical equipment such as
pacemakers. Failure to take the precau-
tions listed below can increase the risk of
severe injury or death due to radio wave
interference.
Anyone who uses electrical medical
equipment such as a pacemaker should
consult the medical equipment supplier
to inquire if radio waves from the keyless
control unit can interfere with the medical
equipment.

16
NOTE:
The key-fob falls under the category of
restricted electronic devices for use in flight.
WARNING

fob while you are in flight. When putting
the key-fob in a bag, etc., protect the but-
tons from accidently being pressed.
NOTICE
The radio waves emitted from the key-fob
may cause interference with other wire-
less communication devices such as
mobile phones and remoter controllers.
Do not operate the buttons on the key-fob
more than necessary.
 CAUTION
Attempting to disassemble (except for
battery replacement), repair, or modify
the key-fob may cause ignition, electric
shock, or injury.
Do NOT attempt to disassemble (except
for battery replacement), repair, or modify
the key-fob.
NOTE:
• Do NOT erase or tamper with the conform-
ance certification mark.
• A maximum of six (6) key-fobs can be regis-
tered in one keyless control unit.
• The battery life of the key-fob is about two (2)
years, which can vary depending on use.
• The key-fob is always in transmission mode
in order to communicate with the keyless
control unit. For this reason, the battery may
run down quickly if it receives strong radio
waves from televisions or personal comput-
ers, etc.
NOTICE
The key-fob is comprised of sophisti-
cated electronic components that can
become damaged and may fail to func-
tion properly if you do not take proper
precaution.
