Figure K1: Day Berth Window
Failure to properly ventilate the boat while the
engines or generator are operating may permit
carbon monoxide to accumulate inside the
accommodation (occupied) spaces. Refer to
Section E- - Engine Exhaust and Section B-
Gasoline vapors can explode resulting in injury
or death. Before starting the engine, check
the engine compartment bilge for gasoline or
vapors, and operate blower for four () min-
utes, and verify blower operation. Run blower
when vessel is operating below cruising speed.
ALWAYS operate the bilge blower while the
engines are at idle.
-
Carbon Monoxide for additional information.
NOTICE
Be sure hatches are secured while underway.
Damage to the hatches may result.

K - 3 HULL DRAINAGE SYSTEMS
A. Transom Drain
Periodic.inspection.and.cleaning.of.the.ventilation.
ducts.is.necessary.to.ensure.adequate.air.circulation..
A.buildup.of.leaves,.twigs,.or.other.debris.can.se-
verely.reduce.ventilation..Be.sure.bilge.water.does.not.
accumulate.to.a.level.that.would.obstruct.the.ventila-
tion.ducts.
A.transom.drain.with.plug.is.provided.in.the.engine.
compartment.to.allow.water.drainage..When.the.boat.
is.out.of.the.water,.the.boat.and.trailer.should.be.
positioned.so.any.bilge.water.accumulation.during.dry.
storage will flow towards the transom.
Blower.operation.can.be.tested.by.placing.a.hand.over.
the.vents..DO.NOT.rely.on.the.sound.of.the.blower..
Be.sure.a.substantial.amount.of.air.is.being.exhausted.
by.the.bilge.blower..Check.the.bilge.blower.system.
often,.preferably.before.each.cruise.
Be sure the drain plug is securely in place
prior to launching the boat. Upon shipment of
the boat, the drain plug is usually taped to the
steering wheel.
Should.blower.noise.and.vibration.be.excessive,.
loosening.the.bilge.blower.mounting.screws.and.then.
tightening.evenly.usually.reduces.noise.considerably.
