I use a vacuum pump on the Yanmar which works well. My question is why the heck these expensive engines do not have oil pan plugs. There is plenty of room to drain into a container in many boats. Screwing around with pumps seems to be a pointless, time wasting, and unnecessary endeavor. Is there some silly law prohibiting drain plugs?
