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 inside of each cylinder.
Rotate the flywheel manually several times to distribute the oil in the
cylinders. Install spark plugs.
Change the engine oil.

Gearcase

Drain and refill the gearcase lubricant (refer to Gearcase Lubrication).

Positioning Outboard for Storage

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.
To prevent problems which can be caused by oil entering the cylinders
from the sump, only store the outboard in one of the three positions
shown.
