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.:facepalm:

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.:yikes:

Good thing I am now a Seacock/Thru hull expert since I read this advice.

New Kohler is now well protected.:biggrin:

Jim...

PS: Working our way back to new sails soon.

Is the generator electrically connected to the seacock? I’m sure the pencil zinc will protect the generator itself, but unless there’s a wire from that to the seacock the seacock won’t be any more protected than before.

Before the discovery if I would have put a bonding wire to AC valve, then yes no bronze loss..
