Graeme - thank you so much for your cheery note :-) I appreciate your
helping us out and describing the assembly details.
I hadn't looked at the valve closely and at first glance thought it was
screwed into the thru-hull instead of being a true seacock integral to the
thru-hull fitting. I obviously need to poke my head in there and study it a
bit.
Inasmuch as the thru-hull itself is well-bedded with no leakage, perhaps I
can find a different way of dealing with the weeping and then add another
shutoff valve in series with the seacock so as not to disturb the thru-hull.
No worries, I'll play with it the next time I haul out, and in the meantime
the slight weeping is captured quite nicely inside that vinyl tube.
Thanks again for your help. JoeS.

Joe, the SW1000 head intake seacock is through foam composite. Therefore
the hole for the fitting is bored through the hull then foam cut out
10-20mm all around. The foam is backfilled with resin "bog" to form a
firm surface for the fitting to screw down on. The fitting is finally
bedded in with Sikkaflex to seal. It may be removed by unscrewing but
the tough Sikkaflex will make the fitting difficult to remove through
the hull. The Sikkafex seal can be broken by turning the fitting with a
Stilsons Plumbing Wrench but this will damage the thread and it will
need to be replaced. Kind Regards, Graeme.

My head intake seacock had been weeping slightly, which resulted in
corrosion between the stainless handle and the valve stem which
eventually ate away the rectangular (bronze?) stempiece to which the
handle is attached.
I've left the valve in the open position, removed the handle, and
clamped a vinyl hose onto the valve body over the valvestem. The top of
the vinyl hose is above the waterline and there is no leakage into the
boat (yes, the hose is full of water up to the waterline). Guess I'll
get ambitious and replace the valve the next time I haul the boat, and
thus the question:
Anything special about removing that valve, as I assume I can remove it
without disturbing the thru-hull by simply unscrewing it?
TIA,
Joe Siudzinski
