12.5. FRESHWATER SYSTEM
This system is best winterized with one of the non-toxic antifreezes available for use in
boat and recreational freshwater systems. It is an easy method, which replaces fresh water
with a non-toxic antifreeze mixture.
Caution! Be sure to use correct non-toxic antifreeze.
1. Allow the hot heater water to cool, and open the pressure release valve on top. Disconnect the hot
and cold water hoses and allow the tank to drain either in a bucket or into the bilge. Connect and clamp
the hot and cold water hoses together using a short length of 1/2" pipe in order to bypass the heater.
2. Mix the appropriate amounts of antifreeze and water, as directed on the label, to deliver the
degree of protection desired. Put 1-1/2 to 2 gallons of the solution into each water tank.
3. Open both tank selector valves on the manifold.
4. Turn on the pump and open all fixtures until antifreeze runs through. Be sure to open the hot
water selector valve in order to supply antifreeze to the hot water hoses and through the bypass loop.
5. At this point, the freshwater system should be completely protected by antifreeze against freezing
to a degree indicated by the strength of the solution placed into the supply tanks.
6. New boats delivered have their freshwater systems filled with antifreeze as described above, and
are protected to -30 degrees F.
12.6. HEAD
Several days before completing haul-out procedures, fresh water should be allowed to
stand in the head unit to dissolve any salt accumulation in the hoses and pump. Remove
all water from the head. Special lubricants for the pump's internal mechanism are
available. Check with your marine hardware dealer for a recommended brand. Never put
oil, gas, kerosene, or alcohol in the head or they will ruin the internal valve.
Completely pump out all waste from the holding tank and pour in a cleansing, deodorizing
solution. If possible, allow this to sit in the tank overnight, then completely pump out and
drain the entire system. If antifreeze is used in the system, check in the manufacturer's
literature for the recommended type.
12.7. ENGINE
Winterization by a marine mechanic is highly recommended to ensure that your engine is
properly protected.
Consult the Engine Owner's Manual for your specific engine's guidelines for winterizing.
Follow the instructions carefully to ensure the engine is adequately protected.
The general procedure is to replace raw seawater with an antifreeze solution mixed to
protect the engine in your local area and to check the heat exchanger side to ensure that it
contains an adequate antifreeze solution as well.
