I have finally corrected the absolute mess I made of the rudder installation. The lower bushing was heavily worn and loose, an inch of rudder tip play in all directions. There was no grease fitting installed in the log at all.
At first I tried to inject a graphite impregnated epoxy mixture into the bearing to tighten it up, but instead of purchasing the correct release wax for the shaft I used cheap car wax. the shaft became epoxied into the bushing and the amount of force required to get it back out cracked the plastic bushing sleeve, ruining the entire bushing assembly. I had to use a 20lb. cast dumbbell weight as a hammer to free it. Much cursing ensued.
The bushing itself is a reduced o.d. 2-3/8 bore standard bronze bushing, and the sleeve is actually a piece of machined 2-1/2" pvc pipe glassed into the hull. I was surprised that a piece of cheap sch40 pvc pipe was used for this application. I assume it was never intended to be beaten so savagely.
I made a new bushing and sleeve using sch80 pipe:

Now onto the next problem, the old rudder is made of steel, wood and heavy fiberglass. It naturally sinks and hangs from the boat from the top cap. The new rudder is made of lightweight foam with a thin shell and is very buoyant, pressing up against the hull instead. I modified the skeg area and made a flattened round area to accept a ride bushing made of nylon to bear this load. the packing box also has an identical bushing between it and the steering arm to capture the rudder and prevent any vertical movement in either direction:

Another thing I found interesting is that this is not patterned off of the 32-2 rudder, it has a different shape that the previous owner and Foss company cooked up. I sure hope it works for the amount of effort it was to install.
If any other EY member is in need of a new 2-3/8 rudder bushing I can create another easily for a reasonable price, I could not find anything like it for sale anywhere.
Anyway that is my rudder adventure, one I hope to never to embark on again! But I am in this thing too far to quit now.
