g

g
enerall
y
located in the center bil
g
e compartment of
y
our boat. It
is mounted about 12” o
ff
the bottom o
f
the bil
g
e. This is
wh
y
it is referred to as a Hi
g
h Water Pump. We discussed
in the DC Electric section about the float switch and
the operation o
f
the pump, so,
y
ou alread
y
understand
that the water level has to be above a hi
g
h water level
to operate this pump. Fi
