It has come to my attention....oil evac units????

I wonder if thay was stock

Can't be too hard to rig something like that up

Not sure if it came that way or not. There was a clip through the end cap that you would just connect in the bilge somewhere near the left side manifold for normal use. It was very handy! That was never an issue for me, the rest the boat was. They "Boats" are great when used regularly!
