Ring Free Fuel Additive
q When the air vent screw is loosened,
gasoline vapor will be released. Gaso-
line is highly flammable, and its vapors
are flammable and explosive. Refrain
from smoking, and keep away from
open flames and sparks while loosen-
ing the air vent screw.
Gasoline is a precise blend of many different
substances, each chosen to give certain
characteristics. Gasoline blends have been
changing in recent years in response to con-
cerns about pollution and resulting emis-
sions regulations. One of the most obvious
changes has been the elimination of lead
from most fuels.
As gasoline has changed, the amount of ad-
ditives such as aromatics and oxygenates
has increased. These additives are impor-
tant for the engines in passenger cars, but
they can have detrimental effects in marine
engines, because of increased deposits in
the combustion chamber. When enough de-
posits collect, piston rings begin sticking.
Performance drops and engine wear in-
creases dramatically.
q This
product emits exhaust gases
which contain carbon monoxide, a col-
orless, odorless gas which could cause
brain damage or death when inhaled.
Symptoms include nausea, dizziness,
and drowsiness. Keep cockpit and cab-
in areas well ventilated. Avoid blocking
exhaust outlets.

If there is an air vent screw on the fuel
tank cap, loosen it 2 or 3 turns.
While many additives available may reduce
deposits, Yamaha recommends the use of
Ring Free Fuel Additive, available from
your Yamaha dealer. Ring Free Fuel Addi-
tive has repeatedly proven its ability to clean
combustion deposits from inside the engine,
notably the critical piston-ring-land area, and
fuel system components. Follow product la-
beling for use instructions.
