Overboard discharge
Important: Overboard discharge of untreated sewage within 12
miles of shore on the east coast and within 9 miles of shore on
the west coast is prohibited by law. Check the local authorities
for proper discharge procedures in your area. If your boat is
going to be used on inland waters, have your dealer seal the
overboard discharge portion of your waste system.
If regulations permit, the macerator can be used to pump waste
from the holding tank overboard. The MACERATOR circuit breaker
at the battery selector switch panel protects the power supply to the
macerator. The macerator pulls the waste from the holding tank,
grinds the waste into small particles, and pumps the waste over-
board through a hull discharge fitting above the water line.
Follow these procedures to operate the macerator:
1. Switch on the MACERATOR switch in the head compartment.
2. Allow the macerator to run until the holding tank is empty, but
not longer. Running the macerator when the tank is empty
will cause damage to the pump.
3. When you hear the pump speed up (indicates tank is empty),
immediately turn the switch off.
Note: If the macerator won’t turn on, check the circuit breaker
at the battery switch panel. If resetting the breaker doesn’t
allow the macerator to turn on, see your dealer to determine
the cause of the problem.
