Exhaust Emissions - Mercury Ocean Runner 290 Owner's Manual

The boat should also be checked for any hull fractures, transom
fractures, or water leaks.
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 low speed.
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.
