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.

WARNING
Gasoline is extremely flammable and
toxic. Always observe the following pre-
cautions 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.
CAUTION
Always use fresh gasoline. Gasoline kept
in the fuel tank for long periods of time
will produce varnish and gum, which can
damage the engine.
CAUTION
Be careful not to spill fuel containing
alcohol while refueling. Fuels containing
alcohol can cause paint damage, which is
not covered under the New Outboard
Motor Limited Warranty.
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
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.
CAUTION
The choice of engine oil is a major factor
affecting engine performance and life.
