Exhaust Emissions - Mercury 40 Jet Manual

GENERAL INFORMATION

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.
Carbon monoxide poisoning can lead to unconsciousness, brain
damage, or death. Keep the boat well ventilated while at rest or
underway and avoid prolonged exposure to carbon monoxide.
GOOD VENTILATION
Ventilate passenger area, open side curtains, or forward hatches
to remove fumes.
Example of desired air flow through the boat
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.
