Strange. I have seen a boat that plumbed the engine freshwater intake to a cockpit vent so you could see if the cooling system stops pushing water. If it is water, it is possible that is what it is, but I doubt the factory ever did that.
Have you traced the hose of the back of the vent to see where it leads?
