Protecting Internal Engine Components

NOTE: Make sure the fuel system has been prepared for storage. Refer to Fuel
System, preceding.
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 kinking 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 Gearcase Lubricant).

Draining Hose Flush Attachment (If Equipped)

If the outboard is stored in freezing temperatures, the hose and flush
attachment should be drained of water. Refer to Maintenance ‑ Flushing
the Cooling System ‑ Models with Hose Flush Attachment.

Positioning Outboard for Storage

Store outboard in an upright (vertical) position to allow water to drain out of the
outboard.
Storing the outboard in a tilted position can damage the outboard. Water
trapped in the cooling passages or rain water collected in the propeller
exhaust outlet in the gearcase can freeze. Store the outboard in the full down
position.

Battery Storage

Follow the battery manufacturer's instructions for storage and charging.
