Frozen Sea Cock Issue

[J. David Bartenfield]

I need helpful advice.

I’ve got a frozen sea cock on my AC inlet through hull.  On the boat side of the through hull is the sea cock with a  5/8 hose attached that leads to a ball valve then a strainer then on to the AC.  The hose is about 4” long and has folded and is severely kinked and I need to replace it to get water to the AC.

The through hull is about a foot below the waterline.  If I clip the hose water is going to come in.

I think I need to stop the water at the outside long enough to replace and clamp the hose.  WHAT IS THE BEST WAY TO DO THIS?  The through hull inlet is about a 1” opening and I can reach it below the waterline from outside.

I’ve heard a plastic bag over the inlet?  

Any advice on how I can safely go about stopping up that through hull from the outside without hauling the boat is appreciated.

David, 

I've successfully regreased a 1" seacock while the boat was in the water. Use a foam rubber stopper pushed into the outside of the hull. Picture can be seen here:  https://www.landfallnavigation.com/truplug-original-plug.html?gclid=Cj0KCQjw6ZOIBhDdARIsAMf8YyEA0hj_2X98yz0tHG1iMn0MkiLyNRlRuJdfPDbRbn6_8aKy39dGnZkaAgYWEALw_wcB

Cut the bulk away and only use the tip. Wave action could pull it out if the entire cone is used. Worked much better than I had expected.
