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.
1. Prior to hauling the boat, run the engine to achieve normal operating temperatures in
order to open the thermostat.
2. Close the raw water intake thru hull and remove the hose from the valve hose barb.
3. Insert the intake hose in a bucket of antifreeze solution and run the engine briefly until
all raw water is flushed thru the exhaust system and only the antifreeze solution is
expelled from the exhaust.
4. Be sure the thru hull valve is opened after the boat is hauled.
FUEL SYSTEM
Consult your engine manual to clean any engine mounted fuel filters.
Drain any water from the bottom of the fuel/water separator.
The fuel tank should be kept full for winter storage with about 5% expansion room left at
the top. Empty fuel tanks encourage the formation of condensation.
BATTERIES
Clean battery terminals and cable ends thoroughly of any corrosion with a baking soda
and water solution, and apply a light protective layer of petroleum jelly.
Batteries should be fully charged before storage, and the fluid level maintained. Store
batteries in a warm, dry place. Do not store batteries directly on a stone or cement floor.
SEACOCKS
Open and drain all seacocks after boat is hauled. Open all seacocks for winter storage.
BILGE
Completely pump out bilge of any water and clean out any debris present. Bilge pumps
should be pumped dry and hoses disconnected, to ensure that no water is left in the
system.
