We're out of the water to diagnose and (hopefully) fix the cause of a frustrating problem - any guesses?

Of course we will take the opportunity to make a proper inspection, scrub and paint, and take care of a few other things.

Can't wait to see your solution and process to resolve the rudder issue. I'm thinking to start, string line fixtured in top and bot gudgeon right on center, then caliper to check alignment at middle ones. Will show gross misalignment, but much less small misalignments in centerline orientation of individual gudgeons. For the rudder, string will need to be fixtured off center same on top and bottom pins, once in the plane of the rudder, then again 90 deg (perp to rudder). In this case, you might be able to pick up angular misalignment because the pins are longer than the gudgeons (measure carefully top and bot of ea pin). In case of rudder, might be easier instead of string, if you had a long rigid straight edge. If you had a long straight shaft or pipe smaller than the gudgeon, could have couple of bushings machined to fit over and closely into gudgeons, then as you install it you would see how it was approaching the next one to find individual angular misalignment. Other crazy ideas, how about a cylindrical laser pointer carefully fixtured in a machined bushing, tape across surface of next gudgeon and see where the dot hits on the tape? I'm betting you have other great ideas on how to approach it. Then the million $ question, what to do about it. Maybe just ream some or all gudgeons out, say 0.005" on dia? Try to find some uber waterproof grease to pump in and give it another go?
