Protecting Internal Engine Components

NOTE: Make sure the fuel system has been prepared for storage. Refer to
Fuel System, preceeding.
IMPORTANT: Refer to Maintenance - Spark Plug Inspection and
Replacement for correct procedure for removing spark plug boots.
Place the outboard in water or connect flushing attachment for
circulating cooling water. Start the engine and let it run in neutral to
warm up.
With engine running at fast idle, stop the fuel flow by disconnecting the
remote fuel line. When engine begins to stall, quickly spray Quicksilver
or Mercury Precision Lubricants Storage Seal into carburetor until
engine stops from lack of fuel.
Remove the spark plugs and inject a five second spray of storage seal
around the inside of the cylinder.
Rotate the flywheel manually several times to distribute the storage
seal in the cylinder. Reinstall spark plug.

Gearcase

Drain and refill the gearcase lubricant (refer to Maintenance - Gearcase
Lubrication).

Positioning Outboard For Storage

Store outboard in an upright (vertical) position to allow water to drain out
of outboard.
If outboard is stored tilted up in freezing temperature, trapped cooling
water or rain water that may have entered the propeller exhaust outlet in
the gearcase could freeze and cause damage to the outboard.

Battery Storage

Follow the battery manufacturer's instructions for storage and
recharging.
Remove the battery from the boat and check water level. Recharge if
necessary.
Store the battery in a cool, dry place.
Periodically check the water level and recharge the battery during
storage.
