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 most fu-
els.
damage or death when inhaled. Symp-
toms include nausea, dizziness, and
drowsiness. Keep cockpit and cabin ar-

As gasoline has changed, the amount of addi-
tives such as aromatics and oxygenates has
increased. These additives are important for
the engines in passenger cars, but they can
have detrimental effects in marine engines,
because of increased deposits in the combus-
tion chamber. When enough deposits collect,
piston rings begin sticking. Performance
drops and engine wear increases dramatical-
ly.

If there is a fuel joint or a fuel cock on the

bustion deposits from inside the engine, nota-
bly the critical piston-ring-land area, and fuel
system components. Follow product labeling
