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.
Z. Maintenance - Liquid Drains
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.double.loop.in.the.drain.line.or.prefabricated.p-traps...
Any.drain.that.terminates.below.the.waterline.is,.by.
virtue.of.its.design,.sealed.against.CO.intrusion...
Some.drains.that.are.below.the.waterline.when.boat..
is.underway.will.be.above.the.waterline.when.the..
boat.is.at.rest..The.location.of.drains,.relative.to.the.
waterline,.can.be.affected.by.the.dynamics.of.boat.
motion.(i.e.,.underway.or.at.rest).
AA. Carbon Monoxide Detection Systems
Four.Winns.has.included.two.CO.detectors.as.a.
standard.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.
CO monitors should be professionally installed
and calibrated. Failure to do so may result in
the improper function of the CO detector.
Never disarm a CO detector. If a CO detector
alarms, immediately ventilate the area and
check passengers for symptoms of CO
intoxication. See your Four Winns dealer for
assistance in diagnosing the cause for the
alarm.

and.maintenance.of.boat.systems,.hazardous.levels.
W. Maintenance - Ventilation Systems
Boats.are.equipped.with.ventilation.systems.to.
eliminate.gasoline.vapors..Blowers.and.fans.may.also.
be.provided.for.ventilation.and.to.mitigate.the.migra-
tion.of.CO.into.occupied.compartments..Attention.
should.be.paid.to.the.following:
1.. Keeping.ventilation.intakes.clear.of.debris
2.. Replacing.damaged.hardware
3.. Maintaining.the.integrity.of.the.ducting.material.
and.its.connections
4.. Ensuring.that.position.of.ducting.intake.is.not.
obstructed.or.restricted,.collapsed,.kinked,..
or.crushed.
5.. Eliminating.sags.in.ducting.that.can.form..
a.water.trap
6.. Checking.hangers.and.other.supports
7.. Ensuring.blower/fan.is.operational
8. Ensuring that airflow is present at discharge
9.. Inspecting.wiring.to.equipment
X. Maintenance - Bulkhead and Deck Integrity
1.. Seal.all.visible.openings.(e.g.,.cracks,.crevices,.
holes,.including.openings.around.wiring.and..
piping.runs).in.bulkheads.and.decks.that.separate.
machinery.compartments.from.occupied.compart-
ments..These.openings.can.permit.migration.of.
CO.vapors.
2.. Check.gaskets.and.sealing.surfaces.on.hatches,.
doors,.and.access.panels.
Y. Maintenance - Air Conditioning Systems
These.systems.can.be.a.source.of.CO.ingress..
and.migration.of.CO.vapors.
1. Keep grilles and filters clean.
2.. 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.
