    This is exactly how OMC did it for their 2 cylinders from ~1957 and
    onward. Before that omc said to choke the engine to stop it. Not that
    great for starting again afterward because it pretty much floods the engine.
    If you waited long enough the engine would probably drain all of the
    flooded gas into the lake.
