There are products that are, supposedly, made for such work: CPES (by Rotdoctor) and Git-Rot (BoatLife). Supposedly CPES penetrates better. Both of them penetrate better than the normal epoxy resin.
However, I have no personal experience on how well they preserve the wood. I used Git-Rot in the past on a project almost exactly like yours (rudder on my C&C 24; it seems that they are very similar). The rudder is still in one piece (10 years later), but I cannot tell if it is because or despite what I did.

Others can correct me here but it seems to me the best approach would be to remove the gudgeon, enlarge the holes and dig out any punky plywood and let the area dry out and re-fill them 1st with clear epoxy (soaks in) and then with thickened epoxy. Then once it's cured re-drill the holes. Same idea as putting holes through your cored deck.

That makes perfect sense. The surveyor said the lower gudgeon was leaking. When I get it down I'll open it up and put a heat lamp on it. Things like this make me thankful to have a 25. What a bigger pain it'd be if I had to deal with a foam cored rudder with a rusted post. Do I seal the gudgeon with silicone, or is there a fitting that needs to be replaced?
