General
Even with the best of boat design and construction plus
utmost care in inspection, operation, and maintenance,
hazardous levels of CO may still be present in accom-
modation spaces under certain conditions. Continuing
observation of passengers for symptoms of CO intoxi-
cation can be supplemented by an alarm type CO detec-
tion device in the accommodation space.

b.
Worn piston rings and valves.
Engine temperature - Cold running engines in-
crease CO production. Engine cooling water
system design and selection of thermostat(s)
are primary considerations affectingengineop-
erating temperature. Generally, an engine pro-
duces less CO if it operates at a relatively high
temperature within manufacturer’s specifica-
tions.
NOTICE
ACO detector is not a gas/fuel vapor detector.
Gas/fuel vapor detectors do not monitor the
buildup of carbon monoxide in an enclosed
area. For further information on the design,
construction, and testing of boats in consider-
ation of carbon monoxide, see ABYC TH-23.

d.
Exhaust Back-Pressure - Certain alterations to
the exhaust system may increase engine ex-
haust back pressure and CO production.
Restricted engine room or compartment venti-
lation.
