I am looking to replace the seacock on my water intake for my 1974 E27 during a haul out. The seacock is in rough shape as you can see. I'm reading that the thru hull is a 1/2" so I'm wondering what size, style, and type of seacock I would need to replace. I'm open to replacing the thruhull as well. Most of the green corrosion could actually be wiped off the thruhull thread and the condition seems to be ok. It would be way less work to only replace the seacock, but I know there's a chance I could damage the thru hull in the process. I'm not sure of the age of the seacock and thruhull, but if I had to guess it was replaced in the 90s during a refit. Any suggestions are welcomed!
