mixture flows from all fresh water faucets. Be sure to open all hot and cold water faucets, including
the fresh water spray head in the stern bait station sink and the water supply valve for the head. Make
sure antifreeze has flowed through all of the fresh water drains.
The shower drain sump system must be properly winterized. Clean debris from the drain and sump
and flush for several minutes with fresh clean water. After the system is clean, pump the drain sump
as dry as possible. Then pour a potable water antifreeze mixture into the shower drain until
antifreeze has been pumped through the entire system and out of the thru-hull.
For additional information please refer to the Fresh Water System chapter.
Raw Water System
Completely drain the raw water systems. 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-mentioned procedure is the use of commercially available
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 fittings and drains. Be sure
antifreeze has flowed through all of the raw water drains.
Make sure to run the stern fishbox macerator pump until all the water is removed from the fishbox
and the pump. To avoid damage to the pump, be careful not to run the pump dry for more than 10
seconds.
Generator Raw Water Systems
Drain the sea strainer, heat exchangers and raw water supply and discharge lines for the optional
generator raw water supply pumps. Make sure all sea water has drained from the exhaust system.
Some, but not all, generator engine mufflers could have a drain plug that must be removed to
properly drain the muffler. Once this is accomplished, pour a nontoxic marine engine antifreeze
mixture into a large pail and put the generator raw water intake lines into the solution. Run the
generator until the antifreeze solution is visible at the exhaust port, then shut the engine off.
Properly winterize the generator engine and fuel system by following the engine manufacturer’s
winterizing procedures located in your engine owner’s manuals or contact a Pursuit dealer.
Marine Toilet
The marine toilet must be properly winterized by following the manufacturer’s winterizing
instructions in the marine toilet owner’s manual. Drain the intake and discharge hoses completely
using low air pressure if necessary. The head holding tank and macerator discharge pump must be
pumped dry and one gallon of potable water antifreeze poured into the tank through the deck waste
pump out fitting. After the antifreeze has been added to the holding tank, open the overboard
