Freeing a stuck blakes seacock lever

Aaaah Steve, why did we not think of doing it yesterday when you were sitting on the sand.

Too busy trying to reverse further onto it

Highly unlikely with the Blakes installed in a Westerly.

Blakes are good - but not indestructible. A few years back a Westerly in the marina here nearly sank when an old Blakes seacock gave way due to long-term galvanic corrosion. Thankfully she was spotted before entirely submerged.

What do you suppose was the mechanism by which an old Blake's , presumably bronze, seacock could have suffered from galvanic corrosion? It must have been in contact with, or connected to, another more cathodic metal or alloy to create the galvanic cell. What would that have been?

Mine would be on someone that decided to connect it to the ground or negative pole of his boat electrical system with other dissimilar metals in the loop.

Easier to replace it with a modern fitting. I have two seized toilet blakes on mine, they are both going in the bin when I lift out

If you put them in the For Sale section for a donation to RNLI or whatever someone else would buy them. Maybe me
