My seacocks also looked good when I changed them, but read:
https://www.myhanse.com/new-seacocks-thruhulls_topic10598_page1.html?KW=seacocks
and you will see on the pictures, that my seacocks after seven years had started to develop reddish rings under the nuts.This is a sign of beginning de-zinkification (read the post).
On the surface my seacocks looked just like yours.
The cost of new Trudesign seacocks are modest, and in my opinion you are gambling with your safety if you plan to continue with the old seacocks.
Your seacocks are probably DNZ/Marine grade brass, but search the net for the lifespan of DNZ. The ball valves are DN20 Kitchen grade brass, which should never have been put in a boat.
I hope that Santa will place a packet with new Trudesign seacocks under your X-mas tree.Wink

Thank you for the advice.
Did you cut the thru-hull with a cutting machine or did you broke it by hand?

It was impossible to loosen the hoses, so I used an angle-grinder to solve the problem. I had to cut the last bit off the hose too. See pictures in the link.
In the link there are two Hanse owners telling about seacocks falling apart because of corrosion.
