My goal is to replace the marine head with a portipotti, which will eliminate the need for the through hull. What do I do with it then. Should I get it plugged and what is the proceedure for doing so? Or should I leave it and have the hoses go where? Thanks in abvance. Danny 86 TR/FK

Hmmm... My goal is to replace the portapotti with a marine head ! I'm thinking ahead (pun?) to some planned multi-week cruises in the San Juan Islands (Washington) and the Sea of Cortez (Mexico) where I want extended storage capacity and the ability to pump overboard in the absense of disposal facilities. (Mexico, offshore)
I've also heard (un-verified) that porta-potti's aren't 'legal' in Canadian waters.

As far as your thru-hull... why not leave a good-quality bronze thru-hull and put a bronze pipe cap on the thru-hull fitting? Probably as reliable as anything short of patching the hull itself... speaking of which, here's a link for good how-to article on permanently plugging a thru hull.

Use the thru hull for your marine air conditioner.....

Don't know why you would want to replace a marine head with a potti, but for sure I agree with Bruce just cap it don't permenantly plug it. Who knows what may come up later. As Oscar said, use it for your AC or maybe add a washdown pump and hook it to the thru hull rather than use fresh water from tanks.

I had my galley to-hull glassed over during my bottom job. The turn-cock and to hull are still there I just plugged the exit and glassed over it. If I were to ever need it I would take that opportunity to upgrade to a proper thru-hull.

I recomend that you remove the hose and cap the fitting. If you ever sell the boat the next owner will have the option of going back to a sea head.

I agree with what others have said. In most instances a functioning head with a holding tank adds value to the boat, a porta-potti subtracts. If you are operating in an area where pumpout facilities are not available, then I would make the conversion in a way that permits you to "convert back" is you decide to sell the boat. Keep you options open. That would include capping the thru-hull. Simply remove the hose and screw on the right sized cap, making sure to wrap the thread wih plumbers' tape (teflon coated) first.
