You said the oil pressure went down to zero. Sounds kind of strange.
A friend in the marine business once told me that a problem like this
(one that occurs after the engine was worked on) is always related some
how to the last repair. I would guess they might have bumped the oil
pressure sending unit or its wire. Give the wire a look and see if its
a tight fit. Before I did anything major at this point, if the
sending unit and wire looks OK, I would replace the sending unit and/or
remove the sending unit and temporarily attach a mechanical guage to
the engine and get a real pressure reading. The reasoning behind this
if the face you said the enging sounded fine even after the pressure
went down to zero.
