RE: Willy's rudder
Larry, Marin,Yes and yes. Had both problems some time ago. See in the photo I took the disc zink off the center of the rudder and put a different type near the top. It won't rattle when it gets a bit consumed. It's no longer in the propwash either. And recently I had the cutlass bearing slide about 1" aft. Pushed it back in, checked the dimple, pulled it back out and drilled the dimples over half way through the bronze cutlass sleeve. It ain't go'in nowhere now.
