Water strainer (typical)
7. Check to be sure that the O-ring under
the cap is intact and replace if neces-
sary.
8. Apply a waterproof grease that is sili -
con- or Teflon-based (do not use petro -
leum-based grease) to the cap threads
and o-ring seasonally, to assure easy
cap loosening for inspections and clean-
ing.
9. Install the filter basket.
10. Install the cap, and tighten by hand.
11. Snug the cap with the spanner wrench.
12. Open the seacock.
13. Start the related engine or pump, and
check the system for leaks.
14. If the strainer is leaking, immediately
close the related seacock and verify
the filter cap is installed correctly with a
good o-ring.
The raw water system must be winterized
before storage. For more information, refer
to section 12, Seasonal Maintenance.
Drainage Systems
Perform these routine maintenance proce-
dures to maintain your drainage system:
• Clean the cockpit drain rails with a hose
and water to remove all debris.
• Clean the hardtop leg drain holes, espe-
cially before winter storage.
• Clean the bilge pump of any debris.
• Check the bilge for debris that can block
the function of the automatic switch.
• Test each automatic bilge pump float
switch each time the boat is used, for
proper operation. Hold two fingers over
the raised circular areas of the switch
for approximately 10 seconds to activate
the pump. Alternatively, add water to the
bilge until the water level is high enough
to activate the pump.
• Test the high water alarm each time the
boat is used. Press the TEST button on
the alarm panel, located in the starboard
cabin lower electrical cabinet.
• Flush all gravity drains with fresh water
periodically, to keep them clean and
free-flowing.
• Clean and inspect the shower and sink
drain sump system periodically; the
sump may be accessed by lifting the
cabin floor hatch. Remove accumulated
debris and flush with fresh water.
CAUTION
!
DO NOT use harsh chemical drain
cleaners in drain systems; permanent
damage to the hoses, fittings and
system can result. Drains and pumps
must be properly winterized before
winter lay-up.
• Operate the thru-hull valves once a
month and service as required.
• Check the drain system regularly to en-
sure it is free-flowing and that the hoses
on the thru-hull fittings are secure and
not leaking.
• Keep the o-ring on the insert end of the
washdown hoses lubricated. Apply a
mild liquid soap such as a liquid dish
soap or boat wash to the insert on the
hose end. For a long-term lubrication
solution, apply petroleum jelly such as
Vasoline. Apply a light coat to the hose
connection and insert it into the wash-
down port. Depending on your location
and usage, a monthly application may
be necessary.
