    I recently acquired a 1995 180 BR. It has a forward thru hull on the starboard side with tubing that extends down past the driver seating area and into the bilge. I can find no explanation for the existence of this thru hull and I see no pump in the bilge. Can someone tell me what this is for??

    How far forward and what size/type of hose? Is the hose just laying there "open" in the bilge?

    My starboard forward through hull fitting is a fuel tank vent hose. It's a fairly large diameter hose. The hose is behind a removable piece of carpeted panel and descends down to the forward Bilge after a anti-siphon loop. If I remove the flooring plate over the tank I can see where the vent hose connects to a 90 degree elbow at the tank. The fitting looks nothing like a bilge pump through hull though. It's a round chromed fitting about an inch across with a small hole facing the waterline and a screen inside the hole. It's just aft of my windshield on a 200 Overnighter.

    No clue if that info will be helpful to you.

    Can you trace back down the hose, into the bilge, to identify what it connects to?
