Regulations prohibit discharging fuel or oily waste
in navigable waters. Discharge is defined as any
action which causes a film, sheen or discoloration
on the water surface, or causes a sludge or emulsion
beneath the water surface. A common violation is
bilge discharge. Use rags or sponges to soak up
fuel or oily waste, then dispose of it properly ashore.
If there is much fuel or oil in the bilge, contact a
knowledgeable marine service to remove it. Never
pump contaminated bilge overboard.
Fill fuel tank(s) less than rated capacity. Allow for
fuel expansion.

enough water in the bilge to raise the float switch
to its highest position; and deactivated when the
water recedes. The pumps should NOT be left in
the MANUAL mode unless the bilge is being
pumped out for servicing.
The emergency bilge pumps and high water float
switches are wired to the systems monitor located
on the dash at the control station (see “SYSTEMS
