a
t

our

is the bil

stem. Your boat is supplied with on
bil

All are part of the Gra

stem. This emer

apacities.
We are concerned about
our sa
et
. You should review
all information contained in this manual, as well as, the
manufacturer’s manuals concernin
all s
stems on
our
boat, but the bil
e pump s
stem will be one that is crucial
to learn. These pumps have the function of clearin
water
from the bil
es of
our boat. You must ensure that the
are kept clean and
unctional in order
or these pumps to
omplete that task.
