I'm just in the midst of buying a used Yanmar 3GM30 engine (I got a deal .
The mechanic I hired to check it out pointed out that the oil pan has NO
drain plug! He did mention that he had drilled and tapped a few Yanmar's
oil pans for a drain fitting to drain it out.

Do you know of anybody else that has done this - I suspect that the oil pan
may have a thicker spot / dummy plug for just this operation?
