Ajax, I'm jealous you are already sailing.....DUDE, I don't even have a Rudder!!!!!! 
Here' the answer to the bronze rudder cap. My explanation was obviously confusing.....No, it is not supposed to be tapered, and it's just a tiny bit out of round. No issues with depth, etc. Guess that during manufacture, the cap was not "perfectly" rounded (but then, neither is my rudder shaft I'm sure).
So answer is, not tapered, just a bit of bronze material left that keeps it from being perfectly round at 2.354 diameter. I called Rudy and left message, but need to try him again to see what he suggests.
Also for Rudder Install: Advice please
Stickboy, you mentioned you've done this before on P30. what is correct way to install?
Is it the following?
Before installing (with epoxy, I understand you want to do a dry run to find out if you need 1 or 2 washers to take up the up and down slop. After determining correct number of washers/spacers, is this the correct order?
1. Bottom bushing put all the way to bottom of rudder shaft at top of rudder (before getting rudder "near the boat")
2. Put epoxy on bottom rudder bushing/rudder tube at the boat
3. Insert Rudder shaft into rudder tube
4. Elevate rudder
5. install top bushing (with epoxy) and washer/spacer(s) (1 or 2 to take up "space")
6. Install bronze rudder cap and bolt.
7. stand back..........
Clean Epoxy residue?
Question: How do you ensure that you don't get residual epoxy "everywhere" or in places that would basically freeze up the movement. I ask this because I'm concerned about being "sloppy" and having epoxy get where I don't want it.
You might avoid alot of epoxy mess by installing the bushings with epoxy and cleaning residual mess, BUT,
****. If you install (epoxy) bottom bushng in the rudder tube, then try to slip rudder shaft all the way through the rudder tube, I can see alot of pressure and manipulation (and time!) trying to "thread the needle". Also, think that it would be just harder to do, or screw up something else, since this is supposed to be a tight fit anyway.
So, what's the right way?
Got my PCV kit from Indigo!!!
