These are limited to allowin
g
over flow or air to escape
the fuel and the holdin
g
and water tanks aboard
y
our boat.
This is one wa
y
that
g
aseous waste products, as well as
in some instances, liquids are disposed. However,
y
ou
should alwa
y
s avoid usin
g
the fuel tank vent as a wa

to
tell i

y
our tanks are

ettin

are a dan

erous hazard.

Basicall
y
, all pumps are somewhat associated with the
Waste

anitation s

stem, but in this section we will
focus on the pumps that are directl
y
associated with the
process o
f
pumpin
g
waste overboard. The suppl
y
f
unc-
tion o
f
these pumps are discussed in other sections
.
Note: The Overboard Discharge Valve should remain closed at
all times except when in use.

P
ro
b
a
bly
t
h
e most
i
mportant pump s
y
stem on
y
our
b
oa
t
is the bil
g
e pump s
y
stem. Your boat is supplied with on
e
bil
g
e pump and one hi
g
h velocit
y
emer
g
enc
y
bil
g
e pump.
All are part of the Gra
y
water s
y
stem. This emer
g
enc
y
bil
g
e pump has the pumpin
g
capacit
y
o

g
allons a
minute from
y
our bil
g
es. Your other bil
g
e pumps var
y
accordin
g
to boat model and size, please refer to th
e
documentation
f
or
y
our bil
g
e pumps
f
or the pumpin
g
c
apacities.
We are concerned about
y
our sa
f
et
y
. You should review
all information contained in this manual, as well as, the
manufacturer’s manuals concernin
g
all s
y
stems on
y
our
boat, but the bil
g
e pump s
y
stem will be one that is crucial
to learn. These pumps have the function of clearin
g
water
from the bil
g
es of
y
our boat. You must ensure that the
y
are kept clean and
f
unctional in order
f
or these pumps to
c
omplete that task.
