.   Heavy sea or out of trim conditions tend to load
engines resulting in reduced performance and
thereby increasing their CO production.
4.   General
a.
b.
Worn piston rings and valves
S.   Portable Generator Sets
Engine temperature - Cold running engines
increase CO production. Engine cooling water
system design and selection of thermostat(s)
are primary considerations affecting engine
operating temperature. Generally, an engine
produces 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 locations which can lead to an increase
in the accumulation of carbon monoxide in the
accommodation (occupied) space. Do not use
gasoline powered portable generators on Four
c.    Exhaust Back-Pressure - Certain alter ati ons
to the exhaust system may in crease engine
exhaust back pressure and CO production.
d.
Restricted engine room or compartment
ventilation

U.   Maintenance - External Conditions
T.   Maintenance - Engine Performance
External conditions that contribute to inefficient engine
performance can include:
Efficient engine performance is vital to minimizing
CO production. The following items are those consid-
ered to have the greatest effect on increased CO
production:
1.
2.
Fouled hull bottom
Damaged and fouled running gear
1.
Fuel Systems - Fuel that is contaminated, stale
or incorrect octane number
(i.e., shaft, strut propeller, rudder and trim tabs)
3.
Incorrect selection of propeller size
2.
Carburetors/Injectors
a.   Dirty or clogged flame arrester
V.   Maintenance - Exhaust System Integrity
b.
Malfunctioning automatic choke plate or faulty
adjustment of manual choke plate
Gas tight integrity of exhaust systems must be
maintained 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:
c.    Worn float needle valve and seat
d.   High float level
e.   Incorrect idle mixture adjustment
1.
Gaskets at cylinder head connection
f.
Dirty or worn injectors
2.
Casting and pipe fittings in the dry section
3.
Ignition System
a.   Fouled or worn spark plug.
3.   All joints
b.
c.
Worn points or incorrect gap on points
4.
Hoses
Shorted or opened circuit high tension spark
plug cables
5.   Clamps
d.
Incorrect ignition timing.
6.
Mufflers and their drain plugs
7.
Thru-hull fittings
8.
Hangers and other supports
