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.
N. Altitude and Sea Conditions
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 propellers size.
1. Failure to make adjustments to ignition systems, fuel
systems, and propeller size may cause an increase
in CO production.
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
Efficient engine performance is vital to minimizing CO
production. The following items are those considered to
have the greatest effect on increased CO production:
1. Fuel Systems - Fuel that is contaminated, stale or
incorrect octane number.
2. Carburetors/Injectors
a. Dirty or clogged flame arrester.
b. Malfunctioning automatic choke plate or faulty
adjustment of manual choke plate.
c. Worn float needle valve and seat.
d. High float level.
e. Incorrect idle mixture adjustment.
f. Dirty or worn injectors.
3. Ignition System
a. Fouled or worn spark plugs.
b. Worn points or incorrect gap on points.
c. Shorted or opened circuit high tension spark plug
cables.
d. Incorrect ignition timing.
4. General
a. Worn piston rings and valves.
b. Engine temperature - Cold running engines in-
crease CO production. Engine cooling water
system design and selection of thermostat(s)
are primary considerations affecting engine op-
erating temperature. Generally, an engine pro-
duces less CO if it operates at a relatively high
temperature within manufacturers specifica-
tions.
c. Exhaust Back-Pressure - Certain alterations to
the exhaust system may increase engine ex-
haust back pressure and CO production.
d. Restricted engine room or compartment venti-
lation.
Q. Maintenance - External Conditions
External conditions that contribute to inefficient engine
performance are:
1. Fouled hull bottom.
2. Damaged and fouled running gear (propeller and
trim tabs).
3. Incorrect selection of propeller size.
