Winterizing; Portable Head; Marine Toilet - Monterey M3 Owner's Manual

Seasonal Maintenance
• Thoroughly clean the interior of the boat.
Vacuum all carpets and dry clean drapes and
upholstery.
• Remove cushions, open as many locker doors
as possible. Leaving as many of these areas
open as possible will improve the boat's ven-
tilation during the storage period.
NOTICE:
It is recommended that a mildew preventer
be hung in the head compartment or cabin
before it is closed for storage.
• Clean the exterior upholstery with a good vinyl
cleaner and dry thoroughly. Spray the weather
covers and boat upholstery with a spray dis-
infectant. Enclosed areas such as the in-floor
compartments, storage locker areas, etc.
should also be sprayed with this disinfectant.

14.2 Winterizing

Fresh Water System
The entire freshwater system must be completely
drained. Disconnect all hoses and blow all the
water from the system. Make sure the freshwater
tank is 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 freshwater pump.
Remove the outlet hose 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
available nontoxic, freshwater system antifreeze.
After draining the potable water tank, lines and
water heater, pour the antifreeze mixture into the
freshwater tank, prime and operate the pump un-
til the mixture flows from all freshwater faucets.
Make sure antifreeze has flowed through all of the
freshwater drains.
For additional information please refer to the
Freshwater System chapter.
Ballast System
Make sure the ballast tank was completely pumped
out before the boat was hauled, if not, pump it
out. Make sure to monitor the tank as it pumps
out and turn the pump off immediately when
pumping is complete. Remember that the pump
will be damaged if it is allowed to run dry for more
than a 15 or 20 seconds.
Close the thru-hull valve and remove the lid on the
intake strainer for the ballast pump. Pour 1 gallon
of potable water anti-freeze into the strainer while
running the ballast pump in the Fill position on
the switch. Turn the pump off immediately when
the strainer empties. Then install the strainer lid
and open the thru-hull valve. This will protect
the pump and the ballast system water lines from
freezing.
Refer to the Ballast System chapter for additional
information on the ballast water system.
Engine Raw Water Systems
Drain all of the sea strainers, heat exchangers and
raw water supply and discharge lines for the en-
gine raw water supply pump. On seawater cooled
engines, make sure to drain both sides of the
engine block, exhaust manifolds and other com-
ponents by following the engine manufacturer's
winterizing instructions. Make sure all seawater
has drained from the exhaust system. Once this
is accomplished, pour a non toxic marine engine
antifreeze mixture into a large pail and put the
engine raw water intake lines into the solution.
Run the engine until the antifreeze solution is vis-
ible at the transom exhaust port or the propeller
exhaust hub, then shut the engine off.
NOTICE:
Properly winterize the engine and fuel sys-
tem by following the engine manufacturer's
winterizing procedures located in your en-
gine owner's manuals or contact a Monterey
dealer.

Portable Head

The portable head must be properly winterized by
following the manufacturer's winterizing instruc-
tions in the portable head owner's manual.

Marine Toilet

The marine toilet must be properly winterized by
following the manufacturer's winterizing instruc-
tions in the marine toilet owner's manual. The
fresh water supply will be winterized with the
fresh water system. Drain the discharge hoses
completely turning off the fresh water supply so
the bowl stays dry and flushing the toilet several
times. The head holding tank and macerator
discharge pump must be pumped dry and three
gallons of potable water antifreeze poured into
