WHILE BOAT IS STATIONARY
Stop your engine immediately whenever anyone in the water is
near your boat. Serious injury to the person in the water is likely
if contacted by a rotating propeller, a moving boat, a moving
gearcase, or any solid device rigidly attached to a moving boat
or gearcase.
Shift into neutral and shut off the engine before allowing people to
swim or be in the water near your boat.

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.
