• 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 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’s performance and life. Always select
