how to plug an unused thruhull
Seeking recommendations on how to best plug an unused 1/2 inch thru hull. It does already have a 1/2 inch male hose fitting. I'm thinking my best option is a short peice of hose and plug the other end with something?

The former owner of my boat jamed a wood plug into the thur hole and then filled it with 5200. Well he had 5200 everywhere, took over 4 hours to remove.

Glass it over. You did say it was unused...

Any other method is potentially prone to failure.

Aye, glass over, fair, match color, polish ... never know it was there!

Next season ... new toy, maybe a/c, genset, sumthin' 'spensive ... oh heck, need water to cool this thing ... guess I'll get 'er hauled and put in a thruhull.

Well, why should Bob be the only one this stuff happens to! :)

Hell - I've got 12 of those underwater. What difference can one more or one less make?

I would double clamp a hose onto it, long enough to loop above the waterline and clamp a wooden plug to the end. Keep the valve shut until you find a new use for it.

Fit a wee stop **** to it, and close the valve?

Glassing and painting sounds tiresome.

aye ... a Folgers coffee can fulla 5200 ... invert ... sploosh ... no worries mate. :)

Why Bob, that's the stupidest thing I've ever heard ... go give yerself a spankin'.

Sorry folks ... it's hot and Bob's just tryin' to avoid another day of sandblasting ... BTW, anyone want a few tons of used sand fulla cat turds????

It depends...if you're positive you're not going to need it for anything... glass it over... if you have future plans that may require a through-hull... do what TB said.

Bob - no use for the sand - but I can lend you a cat

Dang! Perhaps I should advertise ... Free beach and assorted sailing cat stuff. :D
