Hi,
I did not get a picture of the gudgeon in this post. Is it fiberglass or the stainless steel type? If stainless steel, if the correct grade is used, and even with an attachment for a zink, the replacement will be cheap. It will take more than an hour (more likely four), as the fabricator has to shape the steel piece to the shape of the hull in the location of the broken one. The steel gudgeon probably corroded. The fiberglass gudgeon is more difficult to make as I have some experience with that when I decided to make the middle gudgeon more in line (the factory assembled it 1.25" off to the side originally) on Polaris (W32). The W fiberglass gudgeon will not corrode but they are difficult to build and reinstall. I would charge more for this project, as the rudder needs to be taken off and then reinstalled with the pin in place with the Delrin shims as close as possible so that they will not wear away too soon. It would have been easier to build a long pin going through all three gudgeons, but then there is the prop aperture. - What is the going shop rate for boat yards anyway?
