I am replacing all of the Seacocks [9] and discovered this.

This is a new one.

What happened?
The old genset, now gone, had pencil Zinc to protect it.
I found one in the Previous Owners supplies and I changed it, but the PO, never changed it.
Kohler said change every 300 hour of use or 1 per season.
1500 hr of use, when I changed it.
Boat sinking failure waiting to happen.
Good thing I am now a Seacock/Thru hull expert since I read this advice.

New Kohler is now well protected.
Jim...
PS: Working our way back to new sails soon.
