7.6 Drainage System Maintenance
It is essential that the following items be done periodically to
maintain proper drainage of your boat:
• Clean the cockpit and bridge drain rails with a hose to
remove debris that can block water drainage.
• Clean the hardtop or tower 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 accomplished by lifting the float
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 freshwater to keep them clean
and free flowing.
• Clean and inspect the shower and air conditioning drain
sump system. Remove accumulated debris and flush with
freshwater. Frequently test the automatic pump switch for
proper operation.
• Clean and flush the fishbox and cooler storage boxes with
soap or a bilge cleaner and freshwater after each use to
keep them clean and fresh.
• Operate the thru-hull valves once a month and service as
required.
Note: All drains and pumps must be properly winterized
before winter lay-up.
Note: Never use harsh chemical drain cleaners in marine
drain systems. Permanent damage to the hoses and
fittings may result.
