7.3.5 Bil

y
stems
Your boat is equipped with 1 main bil
g
e pump and
1
(O
ptional
)
emer
g
enc
y
bil
g
e pump. For locations
of
the bil
g
e pump s
y
stems, consult
y
our Mechanical
Arran
g
ement Drawin
g
or the
S
anitar
y
Sy
stems Drawin
g.
The Bil
g
e Pump
Sy
stem consists o
f
a pump and a
f
loat
switch. When the water level rises
f
ar enou
g
h to activate
the float switch, this activates the pump which lowers the
water level down to a point that the
f
loat switch stops the
power. Fi

7.3.7 Ventilation
V
entilation is a ver
y
important issue with
y
our boat, with
the potential
f
or
C
arbon Monoxide buildup
(S
ee Boatin

S
afet
y
Section
)
, alon
g
with the simple comfort of fresh
air or air conditionin
g
, ventilation is a standard that is a
necessit
y.
O
n
y
our boat, there are essentiall
y
three t
y
pes o
f
ventila-
tion, the air conditionin
g
s
y
stem
(

)
, the blower,
and the Bomar hatches, which suppl
y
y
ou with fresh
air when opened.
S
ince the air conditionin
g
s
y
stem is
A
C
powered
(
see A

and the hatches
require no power, we will detail the blower
