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.

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
