●
To prevent problems which can be

the attitude shown when transporting
and storing it. If storing or transporting
the outboard motor on its side (not up-

the engine oil.

Do not place the outboard motor on its
side before the cooling water has

Store the outboard motor in a dry, well-
ventilated place, not in direct sunlight.
