Positioning Outboard for Storage
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.
1. Carry, transport, or store the outboard only in the following two positions. These positions will prevent oil from draining out
of the crankcase.
a - Upright position
b - Tiller handle up position
2. Never carry, store, or transport the outboard in the positions shown below. Engine damage could result from oil draining
out of the crankcase.
