That makes perfect sense. I've never taken the after edge of the rudder down to bare wood; thus, missed the plugs. Thanks much for the description.

Odd re the nuts at the end. Wonder what it implies? Extreme pressure on the rods at the bitter end? For boats of our size, the rudder is massive, but thats counter intuitive. Electrolysis? Seems this would have attacked the lower gudgeon first.

Curious to know what you think as you keep working thru. How is the weld where the rod contacts the post holding up?

Do you have the rudder entirely apart? i.e. could you take snaps of the bronze skeleton itself?

Not sure I'd bother with the fill. I've tried to fair the leading edge of Murres rudder with epoxy, but after a few months it blows off from all the water pressure there.

Thanks again.

I have an annode bolted to the prop shaft, which has nearly disentgrated, looks like it's doing it's job. Unless the rudder is grounded to the boat, you may be right, it could be electrolysis. The thru bolts aren't welded to the rudder frame tubing. They have a beveled head on the fore side and sit into a tapered recess in the rudder frame. I had to drive them out from the aft side of the rudder using a long drift punch. I'll get you some pictures this week.
