ROUTINE MAINTENANCE
7-20 53 COUPE
Some local regulations require overboard discharge systems to be
physically secured in a closed position during use of the boat in
waters designated as “no discharge” areas. Check with local boating
regulations. Refer to the system user manual for additional informa -
tion.
NOTICE
7.8 DRAINAGE SYSTEM
The drainage system consists of the forward, mid, and aft bilge pumps; the shower
sump box (graywater macerator drain box); and passive drains.
Before leaving the boat, check all bilge pumps and surrounding bilge areas for
debris that might clog the pumps. Follow the testing procedure in the float switch
user manual to confirm that the switches are turning the pumps on and off prop -
erly. Do not leave your boat unattended until any inoperative bilge pumps
are repaired.
The shower sump box collects drainage, filters some debris, and discharges the
solution overboard ( Figure 7-8 ). The sump box is located in the mid-bilge area,
accessible through the master stateroom floor hatch. Both shower drains, and
condensation from the interior air conditioners, run into the sump box.
The shower sump box should be inspected monthly and cleared of any clogging
debris. Refer to the sump box user manual for clearing instructions.
