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.
