Exhaust Emissions
BE ALERT TO CARBON MONOXIDE POISONING
Carbon monoxide is present in the exhaust fumes of all internal com-
bustion engines including the outboards, stern drives and inboard
engines that propel boats, as well as the generators that power vari-
ous boat accessories. Carbon monoxide is a deadly gas that is odor-
less, colorless and tasteless.
Early symptoms of carbon monoxide poisoning which should not be
confused with seasickness or intoxication, include headache, dizzi-
ness, drowsiness, and nausea.
WARNING
!
Avoid the combination of a running engine and poor ventila-
tion. Prolonged exposure to carbon monoxide in sufficient
concentration can lead to unconsciousness, brain damage, or
death.
GOOD VENTILATION
Ventilate passenger area, open side curtains, or forward hatches to
remove fumes.
1 Example of desired air flow through the boat.
