CARBON CANISTER
T h e d o m e s t i c E PA
compliant fuel tank system
contains a carbon canister.
It is located in the engine
room (bilge or sump).
Its environmental mission is to catch and  lter any
impurities that are attempting to exit the fuel system
via the fuel tank vent hose.  is component should
last the life of the fuel system and requires no periodic
maintenance other than periodically checking the hose
clamps for tightness.
VENTILATION SYSTEM
Stern drive gasoline pro-
p
elled engines require
a continuous supply of
fresh air in order to gen-
erate peak horsepower
and rpm. To deliver fresh
air for the engine a per-
manently mounted vent
system is integrated into
the boat’s a deck on both
port and starboard sides.
 is is called the natural
ventilation system.
When the engine is started
fresh air is drawn through
the vent system. As the de-
mand for air increases in
relationship to the engine
revolutions per minute
(rpm’s) the engine induc-
tion system supplies the
required additional air supply by inhaling more air.
As part of the gasoline combustion process fuel vapors
can accumulate in the bilge and cause a possible explo-
sion or  re. To o set the possibility of this happening a
powered ventilation system exits fuel vapors and pos-
sible CO through a blower with hoses that are strategi-
cally placed in the lower third of the engine compart-
ment.  ere is one blower per engine. Gasoline vapors
naturally seek the bilge bottom and the blowers evacu-
ate any fuel vapors out the exhaust side of the ventila-
tion system.  is is known as the powered ventilation
system. If you are working in the sump make sure you
do not step on the black 4” blower hoses.
Check the vents periodically for any obstructions or
foreign objects such as nests or spider webs. If the pro-
pulsion system is running at a lower than normal cruis-
ing rpm or seems to lack power or the vessel is slow to
plane check the fresh air supply to the engine including
the engine air  lters.
