Hello sail sfbay,
Your my first and only reply. I do not have any photos. What I need is a Transom Plate. They were manufactured by Sillette Ltd in the UK. They were fitted on many British catamarans with a single drive leg (outdrive in US English). It is mounted on the transom and accepts the output shaft from the transmission which goes through a bearing and on the other side is the ujoint and the input shaft for the drive leg. The whole thing is sealed from the inside of the boat and is lubricated by the gear oil in the drive. They were used on Prout, Gemini and others. Mine needs to be replaced but they haven't been manufactured for a few years and I haven't been able to find a replacement. Without it my boat is useless. Any leads, ideas or help would be appreciated.
