Positioning Outboard For Storage

Store outboard in an upright (vertical) position to allow water to drain out of outboard.
If outboard is stored tilted up in freezing temperature, trapped cooling water or rain water that may have entered
the propeller exhaust outlet in the gearcase could freeze and cause damage to the outboard.

Battery Storage

• Follow the battery manufacturer's instructions for storage and recharging.
• Remove the battery from the boat and check water level. Recharge if necessary.
• Store the battery in a cool, dry place.
• Periodically check the water level and recharge the battery during storage.
