9.7 Drainage System Maintenance
It is essential that the following items be done
periodically to maintain proper drainage of your
boat:
• Clean the cockpit drain rails with a hose to
remove debris that can block water drainage.
• Clean the hardtop 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
switches for proper operation. This is accom-
plished by using a garden hose to ood the
bilge until the water level is high enough to
activate the pumps.
• Flush all gravity drains with fresh water to keep
them clean and free owing.
• Clean and ush shboxes, coolers and storage
boxes with soap or a bilge cleaner and fresh
water after each use to keep them clean and
fresh.
• Operate all seacock valves at least once a
month to keep them operating properly.
Note: 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.
