may be on the bow or the gunnel. See
Guide to Individual Models in this Own-
er’s Manual to determine the location of
bilge pump-out. (They are often adja-
cent to ballast overow/vents.) Pump-
outs should never be obstructed.
Operation:
The bilge system is controlled by
a switch on the dash panel. The bilge
pumps on all V-drive models will be in
the automatic mode when the ignition
key is turned ON. Some models may
have two (2) switches, one for the for-
ward bilge and one for the aft. In these
instances, the switches will be marked.
The manual and automatic bilge dis-
charge system is never completely OFF.
When in the automatic (default) posi-
tion, a sensor alerts the system to dis-
charge water from the bilge area.
Boat operators are advised to leave
the switch in the automatic position,
unless there appears to be excess water
in the bilge as viewed through the cen-
ter plate. In that event, the bilge pump
can be manually activated by turning
the bilge pump switch to the manual
ON position.
Return the switch to the automatic
position when nished emptying the
bilge. Leaving the switch in manual
mode can result in damage to the pump
and may not be covered by warranty!
Return the bilge switch to automatic any
time it has been turned to manual to re-
move water from the bilge. Operators
should monitor the water level through
the center drain and ensure that the bilge
pump(s) does not continue to operate af-
ter the bilge is emptied. Note that a small
amount of water in the bilge is acceptable,
except when winterizing the bilge system.
Failure to follow instructions may result in
damage to the bilge system, which may not
be covered under warranty!
Drain plugs should be loosened and
removed when the boat is out of the wa-
ter to allow additional drainage of the
bilge system. Always ensure that the
transom drain plugs have been tightened
in place prior to launching the boat into
the water. Failure to do so can result in
water intruding and overwhelming the
system, sinking the boat.
Transom plugs should be opened only when
the boat is ashore. Removing the plugs al-
lows additional drainage of the bilge sys-
tem. The transom plugs must always be
