7.9 Drainage System Maintenance
It is essential that the following items be done periodically to maintain proper drainage of your boat:
Clean the cockpit drain scuppers and flappers of accumulated marine growth that may hold the flapper
open.
Clean the hardtop and radar arch leg drain holes. This is especially important just before winter lay-up.
Clean the bilge pump strainers of debris and check the bilge for foreign material that can cause the
automatic switch to malfunction.
Frequently test the automatic bilge pump switch for proper operation. This is accomplished by turning
the test knob on the side of the switch until the pump is activated. You can also use a garden hose to flood
the bilge until the water level is high enough to activate the pump.
Flush all gravity drains with fresh water to keep them clean and free flowing.
Clean and inspect the shower and cabin sink drain sump system. Remove accumulated debris and flush
with fresh water. Frequently test the automatic pump switches for proper operation.
Clean and flush the fishbox and cooler storage boxes with soap or a bilge cleaner and fresh water after
each use to keep them clean and fresh.
Operate the thru-hull valves once a month and service as required.
ALL DRAINS AND PUMPS MUST BE PROPERLY WINTERIZED BEFORE WINTER LAY-
UP.
NEVER USE HARSH CHEMICAL DRAIN CLEANERS IN MARINE DRAIN SYSTEMS.
PERMANENT DAMAGE TO THE HOSES AND FITTINGS MAY RESULT.
