Section 3 - On The Water
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 the passenger area, open the side curtains or forward hatches to remove fumes.
1. Example of desired air flow through the boat.

Poor Ventilation

Under certain 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 open
area of a stationary boat that contains or is near an operating engine may be exposed to
a hazardous level of carbon monoxide.

Basic Boat Operation

Drain Plug and Bilge Pump

The engine compartment in your boat is a natural place for water to collect. For this reason,
boats are normally equipped with a drain plug and/or a bilge pump. It is very important to
check these items on a regular basis to ensure that the water level does not come into
contact with your power package. Components on your engine will be damaged if
submerged. Damage caused by submersion is not covered by the Mercury MerCruiser
Limited Warranty.
