The shower/cabin 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 Plumbing Systems 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 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 discharge valve and activate the macerator pump until the
antifreeze solution is visible at the discharge thru-hull.
Make sure you follow the marine toilet manufacturer's winterizing instructions exactly.
AIR CONDITIONER
Disconnect and drain the air conditioner intake and discharge hoses. Remove all water from the sea strainer
and thru-hull fitting. Allow all water to drain from the system. 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, drain the sea strainer and pour the mixture into a pail and put the raw water
intake line into the solution. Run the air conditioner until the antifreeze solution is visible at the discharge
fitting on the hull side.
