Outlet Port to Nowhere

[hriehl1]

I have a 1-inch (or so) outlet fitting in the port hull near the anchor locker... much like my bilge-pump outlets. The hose to it was cut off by the PO 3 or four inches from the interior of the outlet, I have no idea what it may have been for.

I'm not comfortable having what is essentially an open hole in my hull, even if near the rubrail. Are there fittings one can put on the plastic outlet ports to essentially seal them off (like a cap over the barbed hose-fitting)? I'm really not interested in removing the fitting altogether with the accompanying glasswork to repair the hole that would result.

Thanks for any thoughts.

If helpful, I can post inside and outside photos when I'm next at the boat but I think it is just a standard thru-the-hull fitting for bilgewater pump-out.

Continued thanks... this board has been very helpful to me in laying out my fall, winter and next spring timeline of projects.

Hmm.. it wouldn't be a vent hose for an old/original holding tank would it? In a previous life, mine was originally installed in the anchor locker space and i have the exact same hose in mine. Personally, I'm going to be fiberglassing/filling/fairing mine. I don't want any plugs to potentially fail, but that's just my paranoia of "whatever can go wrong, will go wrong" kicking in

I was thinking the same thing: Maybe it was a vent outlet for a water tank or holding tank; that's not an uncommon area for them.

Someone else may have a solution that I am not aware of, but typically through hulls have either NPS (straight) threads (so that you can thread a seacock on), or are barbed so there isn't a good/simple way to cap them (if you search, I had a thread asking this a few years ago).

That's not to say you could not come up with a way.

On the other hand, maybe it will turn out that you want to (re-)use it for vent.

If it is up just below the deck then I don't see it as a significant safety issue. You can add a piece of hose and cap off the end of the hose with a plug (wood dowel?) and hose clamp. You are now as secure as when it was in use. You are sealing it off from an occasional wave in the worst case.

I still say we need to machine up some solid bronze plugs for situations like this......

I need a thread cutting lathe.

I am guessing it was a vent for fresh water. The fresh water tank is now a small flexible type that would not need a vent since it collapses as it is emptied so would not need a vent... but that flexible bag-tank certainly was not original equipment on a 1968 boat.
