and a recommended quantity of diesel fuel stabilizer (only) added to the fuel for winter
storage. Do not add methyl hydrate to diesel fuel, for it will damage the engine.
When the time comes for actual lay-­‐up of the yacht and after the yacht is hauled out,
drain the seawater side of the cooling system and the exhaust system completely. Then
close the engine water intake valve. Disconnect the intake hose and place the end of the
hose in a container of pure ethylene glycol or "permanent" antifreeze. Run the engine
until the antifreeze mixture comes out of the exhaust port. Stop the engine and open all
engine drain plugs as an added safety measure. The coolant in the closed system should be
checked to determine if the solution is of sufficient strength for the winter.
After the antifreezing process, the intake hose should be replaced and made fast to the
intake seacock. Once again, this is the best time to re-­‐open the water intake valve and to
prepare a note to check the valve in the spring prior to starting the engine.
It is recommended that the water pump be removed and kept at home during the
winter or that the impeller be removed and stored in a warm place. Both options are to
prevent permanent "set" in the blades of the impeller which may result from exceptionally
cold weather. An impeller is best stored in a plastic bag with talcum powder. The talc not
only serves as a good preservative, but acts as a lubricant as well.
Finally, insert a wooden plug or oily cloth into the exhaust port at the transom and loosen
the alternator belt. The engine will now be prepared for the winter storage period. If there
are any doubts about proper procedures, you should contact your Dealer, the engine
manufacturer or a qualified mechanic.
