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

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!

little bit of googling shows it was an option at some point, and was made standard later on

i think i like the idea...but since i just bought the evac pump, im gonna run with it
