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.
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.
NOTE:
The separate fuel tank (optional part) is its ded-
icated fuel reservoir and should not be used as
a fuel storage container.
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.
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.
