Seasonal Maintenance
• Clean the exterior upholstery with a good
vinyl cleaner and dry thoroughly. Spray the
weather covers and boat upholstery with a
spray disinfectant. Enclosed areas such as
the shower basin, storage locker areas, etc.
should also be sprayed with this disinfectant.
14.2 Winterizing
Fresh Water System
The entire fresh water system must be completely
drained. Disconnect all hoses, check valves, etc.
and blow all the water from the system. Make sure
the lters and fresh water tank are completely
drained. Use only very low air pressure when
doing this to prevent possible system damage.
Because of the check valve mechanism built in the
pump, blowing the lines will not remove the water
from the fresh water pump. Remove the inlet
and outlet hoses on the pump. Turn the pump on
and allow it to pump out any remaining water....
about a cupful.
A recommended alternative to the above-men-
tioned procedure is the use of commercially avail-
able non toxic, fresh water system antifreeze.
After draining the fresh water tank, lines and
lters, pour the antifreeze mixture into the fresh
water tank, prime and operate the pump until the
mixture ows from all fresh water faucets. Be sure
to open all water faucets, including the fresh water
washdown hose. Make sure antifreeze has owed
through all of the fresh water drains.
For additional information refer to the Fresh Water
System and Drainage Systems chapters.
Raw Water System
Completely drain the raw water systems including
the sea strainers in the stern bilge. Disconnect
all hoses and blow the water from the system.
Use only very low air pressure when doing this
to prevent possible system damage. Because of
the check valve mechanism built in the raw water
washdown pump, blowing the lines will not remove
the water from the raw water pump. Remove
the inlet and outlet hoses on the pump. Turn the
pump on and allow it to pump out any remaining
water....about a cupful.
A recommended alternative to the above-men-
tioned procedure is the use of commercially avail-
able nontoxic, potable water system antifreeze. If
potable water antifreeze is used, pour the mixture
into a pail and put the raw water intake lines into
the solution. Run the pumps one at a time until
the antifreeze solution is visible at all raw water
faucets and discharge ttings and drains. Be sure
antifreeze has owed through all of the raw water
drains.
Make sure to run the sh box pumps until all the
water is removed from the sh boxes and the
pump. Then pour potable water antifreeze in each
sh box and activate the pumps until antifreeze is
visible at the discharge thru-hull ttings. To avoid
damage to the pump, be careful not to run the
pump dry for more than a few seconds.
Make sure all water is removed from the livewell
and that the drain is clear and free owing. In-
stall the livewell drain plug, pour potable water
antifreeze in livewell and activate the recirculation
pump until antifreeze is visible at the discharge
tting. Remove the drain plug and wipe down the
inside of the baitwell.
Refer to the Raw Water System chapter for ad-
ditional information on the raw water system.
Marine Toilet
The marine toilet must be properly winterized by
following the manufacturer’s winterizing instruc-
tions in the marine toilet owner’s manual. Drain
the intake and discharge hoses completely using
low air pressure if necessary. The head hold-
ing tank and overboard discharge pump must
be pumped dry and one gallon of potable water
antifreeze poured into the tank through the deck
waste pump out tting. After the antifreeze has
been added to the holding tank, open the over-
board discharge valve and activate the overboard
macerator pump until the antifreeze solution is
visible at the discharge thru-hull.
Notice:
Make sure you follow the marine toilet manu-
facturer’s winterizing instructions exactly.
Portable Marine Toilet
The portable head must be properly winterized by
following the manufacturer’s winterizing instruc-
tions in the portable head owner’s manual.
Notice:
Make sure you follow the marine toilet manu-
facturer’s winterizing instructions exactly.
