, preceding.
System
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 Gearcase Lubricant).

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.
• Remove the battery from the boat and check water level. Charge if
necessary.
• Store the battery in a cool, dry place.
• Periodically check the water level and charge the battery during storage.
