Opening and closing ports, hatches, doors, and win- N. Altitude and Sea Conditions
dows may raise or lower CO levels on board a boat.
See Figures H5 and H6.
Changes in altitude greater than 5,000 feet contribute to
inefficient engine performance and may require adjust-
ments to the ignition systems, fuel systems, or changing
the propeller’s size.
1.
Failure to make adjustments to ignition systems, fuel
systems, and propeller size may cause an increase
in CO production.
Figure H5: Desired air flow through the boat.
2.
Heavy sea conditions tend to load engines resulting
in reduced performance and thereby increasing their
CO production.
O. Portable Generator Sets
Gasoline powered portable generators are available in
the marine market place and are not an option available
through Four Winns. Portable generators will produce
CO. These sets discharge their exhaust products in lo-
cations which can lead to an increase in the accumula-
tion of carbon monoxide in the accommodation space.
This equipment is not recommended for use on Four
Winns boats.

P.
Maintenance - Engine Performance
Exhaust fumes from engines contain carbon
monoxide. Boats with canvas deployed are
more likely to collect exhaust fumes. Avoid
brain damage or death from carbon monox-
ide. Keep cockpit and cabin areas well venti-
lated. Signs of exposure include nausea, diz-
ziness, and drowsiness. If using a catalytic
heater, provide ventilation. Do not use cata-
Efficient engine performance is vital to minimizing CO
production. The following items are those considered to
have the greatest effect on increased CO production:

Fuel Systems - Fuel that is contaminated, stale or
incorrect octane number.

Boats having fuel burning appliances in accommodation
areas should be provided with adequate ventilation and
maintained to function properly.

M. Ventilation of Accommodation Spaces
Accommodation spaces need to be ventilated to intro-
duce fresh air into the spaces. Ventilation method; e.g.
windows, hatches, doors, and blowers; used to accom-
plish this may, under certain conditions, bring hazard-
ous levels of CO into the accommodation spaces. Care
should be taken to be aware of all prevailing conditions
when using these ventilating methods.
Incorrect idle mixture adjustment.
Dirty or worn injectors.

Ignition System
Fouled or worn spark plugs.
