I posted these last year but for anybody who is interested here is a link to the pictures of my rudder being rebuilt.
https://drive.google.com/folder/d/0B8pEh5lnvP1yVUdWUDNxVGFUcDA/edit Steve Uthoff at Annapolis Fiberglass and Gelcoat did a fantastic job. He did find some interesting problems including the lack of ANY bonding of the SS web to either side of the rudder. No corrosion on the web though. Looked like most of the water was comming down the shaft. He ground out a v-groove around the shaft and filed it with g-flex.
