(5) Stop filling when the fuel just becomes
visible in the bottom of the filler tube. Do
not “top off” the tank, because gasoline
could spill out.
(6) Wipe up any spilled fuel immediately.
(7) Close the fuel tank filler cap by pushing it
until it locks in place. Make sure that the
fuel tank filler cap is securely closed.
Ring Free Fuel Additive
Gasoline is a precise blend of many different
substances, each chosen to give certain char-
acteristics. Gasoline blends have been
changing in recent years in response to con-
cerns about pollution and resulting emissions
regulations. One of the most obvious changes
has been the elimination of lead from fuels.
As gasoline has changed, the amount of addi-
tives such as aromatics and oxygenates has
increased. These additives are important for
the engine in passenger cars, but they can
have detrimental effects in marine engines.
While many additives available may reduce
deposits, Yamaha recommends the use of
Ring Free Fuel Additive, available from a
Yamaha Boat Dealer. Ring Free Fuel Additive
has repeatedly proven its ability to clean com-
bustion deposits from inside the engine, nota-
bly in the critical piston-ring-land area, and
fuel system components. Follow product la-
beling for use instructions.
