Wet sumps.
IIRC, my Honda 8 owners manual, they say to set it down only on it's
carry handle, which gives it a slight downward tilt, but for long term
storage is best to have upright.

Since we've got another going on outboards, another question comes
to mind viz-a-viz two stroke vs four stroke storage.

Do the four stroke motors have a dry sump, if not can you store the
motor in any position without loss of crankcase oil?
