1. DO NOT allow the boat to remain stationary with
the engines running for an extended period of
time. Do not stand or swim near the exhaust
output or drives when the engine is idling.
2. Use extreme caution while operating the en gines
in confined areas such as enclosed slips, congest-
ed piers, or in any area where the exhaust outlets
are facing or near a bulk head or wall structure of
any kind. Operation under such conditions could
easily lead to exhaust gases (carbon monoxide)
entering even though you may have all the
hatches, windows, doors and portholes closed.
3. Never operate your generator while the boat is
moored against any other boat, dock or wall
structure that is against or near the exhaust outlet.
Again, operation under such conditions could
easily lead to exhaust gases (carbon monoxide)
entering your boat or the boat to which you are
moored, even though you may have all the
hatch es, windows, doors, and portholes closed.
4. Under certain conditions, exhaust gases can enter
the boat through the sink drains. Each sink drain
has a water trap installed to help prevent this. To
be effective, the sink drains must have water in
them. Normal use of the sinks will provide the
water needed for this to occur.
5. Persons sleeping can be easily overcome by
carbon monoxide because they are unaware of its
presence. Sleeping with the engines or generator
running is not recommended. If persons are
sleeping aboard while underway, or while the
generator is running, those awake should monitor
for carbon monoxide accumulation in the cabin;
especially the sleeping areas. Open forward facing
windows or deck hatches to provide fresh air
ventilation. Keep hatches, windows, and doorways
that face aft or towards the exhaust discharge
closed.
NEVER operate the propulsion engine(s) or
generator while everyone on board is sleeping.
Fatal carbon monoxide poison ing can occur.
6. If possible, ventilate your cabin while under way.
Open a forward hatch or window to allow air to
travel through the cabin. Do not operat e the boat
with the cabin door(s) or windows that face aft,
open. The natural vacuum created during opera-
tion may allow exhaust gasses to be drawn into
the cabin.
Engines, Drives and Instrumentation - Section E
Carbon Monoxide - Cabin Doors Warning Label
NOTICE
The forward deck hatch, portlights and port and
starboard windows are designed to allow
ventilation when placed in open position.
7. Inspect the engine exhaust system frequently for
water and exhaust gas leakage, hose deteriora-
tion, and loose hose clamps. See Section R -
General Maintenance for additional information.
8. Have a certified marine engine service techni c ian
inspect your exhaust system whenever your boat
is in for service, or if you notice a change in the
sound of your engines.
For additional information, refer to Section B-2 - Car-
bon Monoxide.
B. Carbon Monoxide Monitors
A carbon monoxide (CO) monitor(s) will sound an alert
should carbon monoxide reach an unsafe level in the
cabin. The CO monitors are standard equipment and
are generally located in the aft cabin, forward cabin
and main cabin. CO monitors locations will vary
depending on V series model. Refer to the CO
monitor's manu facturer literature included with the
owner's packet.
Never disarm a CO detector. If a CO detector
alarms, immediately ventilate the area and
check passengers for symptoms of CO
intoxication. See your Four Winns dealer for
assistance in diagnosing the cause for the
alarm.
