FRESH WATER SYSTEM
Modern boats can have complicated plumbing systems, including water-cooled refridgerators,
air-conditoning units, electric flush
toilets and many pumps designed
to move water. Each of these items
requires proper winterization.
The boat's holding tank
should be pumped out prior to
haul out, and a septic cleaner run
through from the head to the holding tank. Products like Head-omatic's 'Shock Treat' are ideal for
this purpose.
Next - drain water from every
area of the boat. This list should
include:

heads and other potable water fittings: propylene glycol has
been proven to damage neoprene and nylon components.
Running antifreeze through pumps that use neoprene diaphragm risks future damage. Many modern pumps employ a
centrifugal design that allows them to safely pump antifreeze.
Modern marine toilets can also be problematic: the joker valve
(the valve that allows waste out and prevents it from flowing
back into the bowl) is particularly susceptible to damage from
antifreeze.

1) Fresh water tank (water pump
and open faucets until the tank is
empty)
2) Disconnect the shore water line
3) Drain the bilge completely (a sponge can help remove the
last few mm)
4) Drain the hot water tank by opening the drain cock.
Bypass the hot water tank so that any antifreeze run through
the lines won't enter the hot water tank
5) Disconnect the water lines at the lowest point and allow
the lines to drain
6) Drain every sea-water strainer by opening the drain nut
7) Pump out any water in the head
8) Drain the shower sump
9) Use compressed air to blow through the water lines
10) Run antifreeze (the same polypropylene glycol used for
the engine) through the lines. I tend to use a hand-pump, but
the boat's electrical pumps can be used as well
11) Run antifreeze through the head, by disconnecting the
water inlet and pouring antifreeze in as the pump/flush is
engaged.
12) Pour antifreeze in the shower drain into the sump and run
the pump until it flows overboard
13) Pour antifreeze in the bilge areas and run the pumps until
it flows overboard
14) Pour antifreeze into the livewell areas and run the pumps
15) Pour antifreeze into the air-conditioner pump inlet and
run the pump until it flows overboard
16) Run antifreeze through any other fresh water source:
cockpit showers, wash-down faucets, refrigerator lines, etc

Many modern boats utilize PEX tubing (crosslinked
polyethylene pipe) which is very versatile and well suited to
the marine environment. It is inexpensive to buy and install
and a simple system to maintain. It tends to stretch rather than
crack or break when frozen water expands inside, but still
must be drained and winterized to prevent long-term damage
(especially in the connectors).
A note here on running antifreeze through pumps, lines,

BATTERIES
Flooded cell batteries must be maintained correctly in
order to winterize properly. The fluid inside a flooded battery
changes its chemical composition depending on its state of
charge: a fully charged battery is primarily sulphuric acid,
where a discharged (partially drained) battery is full of water.
Water freezes, while sulphuric acid does not. So, of prime
importance is ensuring that batteries are fully charged before
the boat is left in freezing temperatures.
In order to keep the batteries in a charged state, they
should be disconnected while stored. Theoretically, a disconnected battery will have the same charge once reconnected in
the spring as it does when put in storage in the fall.
Prior to winter storage, and when reconnecting in the
spring, the battery should be load tested and the battery terminals should be torqued to the manufacturer's specifications.

This is what can happen to batteries that freeze. Photo: Rolls Battery
