Before starting the engine, press the bilge pump
switch so that the switch light comes ON. Make sure
the pump is working by opening the engine
compartment, listening to hear the pump running
and check to see that liquid is being pumped out
from the hull discharge (See Fig. 2.10.1). If the bilge
has more liquid than normal, see Maintenance
Section for locating and correcting the problem.
Except for checking the operation of the bilge pump
using the ON position, leave the switch in the OFF
(AUTO) position. In the OFF (AUTO) position, when
the bilge liquid is deep enough to activate the float
switch, the bilge pump turns on and pumps out the
bilge liquid until the float switch drops and shuts off
the pump.
SINKING HAZARD – Ensure the bilge pumps are
operating properly.
! WARNING
Run bilge pumps in the manual position only as
long as necessary to remove water. Running bilge
pumps dry can damage the pump motor.
! CAUTION
