Thanks for the advice. I went out to the boat and checked my repair this morning. BONE DRY!
HS, are you saying that with a gob of beeswax over the intake, I can spin the old valve off and replace it? I'm a bit nervous about applying too much pressure and maybe snapping off the nipple that sticks out of the hull. I have soaked the fitting with seafoam in hopes that it will break free easy. I will take your advice on the quality of the replacement for sure.
One crazy idea I had: the slip next to me is vacant. What if I took the main halyard and attached it to a cleat on the vacant slip finger and then winched it in. I'm thinking it would heal the boat enough to raise the intake out of the water. I could then hopefully replace the valve without worry of taking on more water.
Anyway, here is the culprit:
and the temporary repair
Picure quailty is kinda poor, used another camera.
Thanks again for the advice, oh, and where do you get those "tampons"? I googled them and only found a manufacturer, no distributor yet, although I haven't checked out West, or others yet either.
