WARNING
You must take precautions to reduce the chance of
accidents and injuries resulting from the use of your
outboard motor and boat. Some of the important
safety precautions you should take are:
ŸBefore first use of your outboard motor, read
this owner's manual carefully to become fa-
miliar with the outboard motor's features, safety
requirements, and maintenance requirements.
ŸBefore each use of your boat, perform a daily
inspection. Specific items to check are listed in
the INSPECTION BEFORE BOATING section.
ŸNever run the outboard motor indoors or in an
enclosed area. Exhaust emissions contain
poisonous carbon monoxide fumes which can
cause unconsciousness and may lead to death.
ŸNever operate your boat while under the
influence of alcohol or other drugs.
ŸPractice operating your boat at slow and
moderate speeds until you become thor-
oughly familiar with the operating and han-
dling characteristics of your motor/boat
combination. Do not operate your outboard
motor at maximum performance until you are
thoroughly familiar with these characteristics.
ŸBe sure that you and your passengers always
wear life jackets on board.
ŸWhen loading your boat, distribute weight
evenly between the bow and stern, and the
port and starboard sides.
ŸObserve periodic maintenance require-ments-
your authorized Suzuki Marine Dealer is
trained and equipped to perform this service.
ŸDo not modify your outboard motor. Modifi-
cations or removal of original equipment may
make the motor unsafe.
ŸLearn and obey the navigation rules of the
locality in which you operate your boat.
ŸMake sure you have the necessary emer-
gency equipment on board such as a flotation
device for each passenger, fire extinguisher,
signaling devices, anchor, paddles, bilge
pump, rope, first-aid kit, tool kit, emergency
starter rope, flashlight, extra fuel and oil, etc.
ŸInstruct your passengers about emergency
procedures. Make sure they understand the
basics of how to operate the boat, how to use
emergency equipment, and what to do in case
of trouble.
ŸDo not hold onto the motor cover or any other
parts of your outboard motor while getting on
or off your boat.
ŸCheck the weather forecast before boating to
avoid bad weather.
ŸUse extreme caution when replacing a part
on your outboard motor or selecting and
installing accessories. Use of inappropriate
or poor quality replacement parts or accesso-
ries can create unsafe operating conditions,
or result in damage to the motor. Suzuki
strongly recommends that you use genuine
Suzuki replacement parts and accessories as
damage caused by use of parts and ac-
cessories other than genuine Suzuki re-
placement parts and accessories will not be
covered under warranty.

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.
CAUTION
If leaded gasoline is used, engine
damage may result. Use only unleaded
gasoline.

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 contain
alcohol.
Gasoline/Ethanol Blends
Blends of unleaded gasoline and ethanol (grain
alcohol), also known as gasohol, are commer-
cially available in some areas. Gasoline contain-
ing a maximum of 10% ethanol may be used in
your outboard motor without jeopardizing 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 circumstances. 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.
Pump Labelling for Gasoline/Alcohol
Blends
In some states, pumps that dispense gasoline/
alcohol blends are required to be labelled 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 content 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 station
operator or the fuel suppliers.
