Protecting Internal Engine Components

Remove the spark plugs and add approximately 30 ml (1 oz) of engine oil
or inject a five second spray of storage seal into each spark plug hole.
Rotate the flywheel manually several times to distribute the oil in the
cylinders. Reinstall spark plugs.
Change the engine oil.

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.
