So, I am assuming that when they designed the one peice gudgeions that they didn't intend it to be used as a retrofit on older boats, correct?
It seems that with a lost sand casting process someone could make up a 'retrofit casting' to replace existing one with a better design and easier installation, or even just mill it. Does lack of volume prohibit this?
It wasn't designed for the US boat or the North American market at all. It was transferred directly over from the H-16 sold in Europe. In fairness though, everywhere I've seen it sold comes with a disclaimer that it is not a direct replacement. Co-incidently many boats I've seen with this backfit also have an inspection port at the stern. I'm guessing a lot of transoms have been mangled in the process. The truth is that there is really nothing wrong with the original design. It is a big chunk of stainless steel and very sturdy. This one piece gudgeon buys you no improvement whatsoever that I can see.
