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
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
Lubrication).
Positioning Outboard for Storage
Store outboard in an upright (vertical) position to allow water to
drain out of the outboard.
NOTICE
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
recharging.
