Exhaust Emissions

BE ALERT TO CARBON MONOXIDE POISONING
Carbon monoxide is present in the exhaust fumes of all internal combustion
engines. This includes the outboards, sterndrives and inboard engines that
propel boats, as well as the generators that power various boat
accessories. Carbon monoxide is a deadly gas that is odorless, colorless
and tasteless.
Early symptoms of carbon monoxide poisoning which should not be
confused with seasickness or intoxication, include headache, dizziness,
drowsiness, and nausea.
Avoid the combination of a running engine and poor ventilation.
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.
POOR VENTILATION
Under certain running and/or wind conditions, permanently enclosed or
canvas enclosed cabins or cockpits with insufficient ventilation may draw
in carbon monoxide. Install one or more carbon monoxide detectors in your
boat.
Although the occurrence is rare, on a very calm day, swimmers and
passengers in an enclosed area of a stationary boat that contains or is near
a running engine may be exposed to a hazardous level of carbon
monoxide.
