So, a friend bought a sailboat............without asking my opinion of it first. Let's be kind and say the boat needs, uh, work.
Since this is a live-aboard, the first order of business is a working head. Installed now is your standard issue Jabesco and I will replace it with the same as well as replacing the waste impregnated hoses and stainless clamps. The boat is in the water.
Now my question, since I believe in Murphy's Law and live by my Dad's motto, "Hope for the best, expect the worst" I want to temporarily plug the through-hull fitting for waste, (which of course is below the waterline) to protect the boat from flooding in the event I break the seacock or suffer some other misadventure.
My thought is to use a plug like is used to plug plumbing pipes to test for leaks.
You have no idea how much I would appreciate guidance on this operation.
