Exhaust Emissions - Mercury 135 Verado FourStroke Operation And Maintenance Manual

GENERAL INFORMATION
Operating a damaged outboard could cause additional damage to other parts
of the outboard or could affect control of the boat. If continued running is
necessary, do so at greatly reduced speeds.
Operating a boat or engine with impact damage can result in product
damage, serious injury, or death. If the vessel experiences any form of
impact, have an authorized Mercury Marine dealer inspect and repair the
vessel or power package.

Exhaust Emissions

BE ALERT TO CARBON MONOXIDE POISONING
Carbon monoxide (CO) is a deadly gas that is present in the exhaust fumes of
all internal combustion engines, including the engines that propel boats, and
the generators that power boat accessories. By itself, CO is odorless, colorless,
and tasteless, but if you can smell or taste engine exhaust, you are inhaling
CO.
Early symptoms of carbon monoxide poisoning, which are similar to the
symptoms of seasickness and intoxication, include headache, dizziness,
drowsiness, and nausea.
Inhaling engine exhaust gases can result in carbon monoxide poisoning,
which can lead to unconsciousness, brain damage, or death. Avoid exposure
to carbon monoxide.
Stay clear from exhaust areas when engine is running. Keep the boat
well‑ventilated while at rest or underway.
