Controls
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.

operation before starting the engine.
The controls should work smoothly, without
binding or unusual free play.
