Heavy sea or out of trim conditions tend to load en-
gines resulting in reduced performance and thereby
increasing their CO production.

Worn piston rings and valves
S. Portable Generator Sets
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.
Never use a portable generator on a boat.
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 cause accumulation of carbon mon-
oxide in the accommodation space. Do not use gaso-
line powered portable generators on Four Winns®
boats.

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

Maintenance - Engine Performance
U. Maintenance - External Conditions
Efficient engine performance is vital to minimizing CO
production. The following items are those considered to
have the greatest effect on increased CO production:
External conditions that contribute to inefficient engine
performance can include:
1.
2.
Fuel Systems - Fuel that is contaminated, stale or
incorrect octane number

2.
Fouled hull bottom
Damaged and fouled running gear (i.e., shaft, strut
propeller, rudder and trim tabs)
Carburetors/Injectors
a.
b.
Dirty or clogged flame arrester
3.
Incorrect selection of propeller size
Malfunctioning automatic choke plate or faulty
adjustment of manual choke plate
V. Maintenance - Exhaust System Integrity
Gas tight integrity of exhaust systems must be main-
tained to insure that leakage of CO within the boat does
not occur. Disassembly may be required to carry out a
thorough inspection. Repair or replace components
as indicated. Inspect the following:
