Carbon Monoxide Monitor; Engine & Drive System - Four winns 338 Vista Owner's Manual

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.

NOTICE
Current deck hatches are designed to allow
ventilation when latched in a partially 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 competent marine engine service techni-
cian 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 -
Carbon Monoxide.
B. Carbon Monoxide Monitor
A carbon monoxide (CO) monitor(s) will sound an
alert should carbon monoxide reach an unsafe level
in the cabin of your Vista
standard equipment and are located in the aft cabin
and forward cabin. Refer to the manu facturer's
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.
