I am a semi retired tech. who found this site very recently. I have been very impressed with the responsible answers to ?. I do not chime in if I do not have knowledge or access to answers. in my collection of parts and service manuals. dating from 1940 to 2000. Mostly John/Rude, OMC SD, and Mercruiser SD. I very much appreciate the absolute adherance to safety. and common sense. I do have a lot of old parts in my shed, and special tools. I am trying to put an inventory together but time does not allow at this time. If I am able to assist anyone please feel free to get in touch with me. I am however going to be out of town frequently, as I also am a licensed Capt.. Hope to talk to many of you soonly and help you with whatever I can. Good sailing Bill
