V. Maintenance - Exhaust System Integrity
X. Maintenance - Bulkhead and Deck Integrity
Gas tight integrity of exhaust systems must be main- 1. Seal all visible openings (e.g., cracks, crevices,
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:
holes, including openings around wiring and piping
runs) in bulkheads and decks that separate ma-
chinery compartments from occupied compart-
ments. These openings can permit migration of
CO vapors.

Seal bulkhead voids and openings at wiring and
piping runs in return air ducting, plenums, and air
handling equipment enclosures, especially those
adjacent to machinery compartment bulkheads.

8. Hangers and other supports
W. Maintenance - Ventilation Systems
3. Check that water traps and condensate drains are
present. These may be in the form of a double
loop in the drain line or prefabricated p-traps. Any
drain that discharges below the waterline when the
boat is underway is sealed, by virtue of its design,
against CO intrusion.
Boats are equipped with ventilation systems to elimi-
nate gasoline vapors. Blowers and fans may also be
provided for ventilation and to mitigate the migration of
CO into occupied compartments. Attention should be
paid to the following:
Z. Maintenance - Liquid Drains
1.
Keeping ventilation intakes clear of debris
Sink, shower and condensate drains can be a source
of CO ingress. Ensure that water traps are present
and contain fluid. These traps may be in the form of a

AA.CO Detection System
Four Winns has included two CO detectors as a stan-
dard feature. One of the CO detectors is located in the
forward V-berth and the other is located in the aft/mid
cabin. Check systems and maintain in accordance with
the manufacturer’s instructions.
