cooling water pump may freeze and
severely damage the pump, impeller,
and associated parts. To avoid this,
submerge the lower half of the engine
into the water, or tilt the engine and
operate the electric starter motor for
5 seconds with the stop switch lock
plate taken away to allow the water to
drain completely.
