CHAPTER 3
ENGINE EXHAUST SYSTEM
Your engine expels the by-products of the engine operation through
an exhaust system, just like cars do. In boats however, this exhaust
system mixes the debris left over after the power stroke of the engine
with the hot water that is expelled after cooling the engine.
Basically the exhaust
fl
ows through the powerhead before expelling
the exhaust through the vertical drive housing either just above the
propeller, or through the prop shaft.
ENGINE FUEL SYSTEM
All engines require a source of fuel in order to run. The fuel that an
engine uses, is not only comprised of gasoline (in some cases diesel),
but also air. This mixture of gas and air are combined into a ratio,
best suited for your engine and boat. If this system fails, the engine
will have no fuel to compress and ignite. It is important to make sure
your fuel system is functioning properly.
!
WARNING
GASOLINE VAPORS CAN EXPLODE. BEFORE STARTING THE
ENGINE, CHECK ENGINE COMPARTMENT FOR GASOLINE LEAKS
OR VAPORS.
