Went to look at the boat my son boat today and spent some time going over it while sitting on a sandbar in the St. Croix River.
The engine (5.0) manual says to use a vacuum pump to extract the oil from the crankcase. Doesn't look like it's reasonable to drain into the bilge, but I'm wondering how well sucking the oil out gets the bottom of the pan clean.
