Crew,I'd be interested in any information on the Yanmar diesel installed in my 78 H27. I'd like to know if there is a source for an owner's manual for the engine. One for the boat would be a nice to have item as well. Anyone know of a source?By the way, I've posted a couple of things on this site and truely appreciate the time you all have taken to answer my questions. As a sailor for over 30 years and going on my fifth boat, I look forward to sharing my knowledge whenever I can. Experienced in woodwork, machining and welding (TIG, MIG, and stick with SS, AL, and steel) as well as building engines for classic cars (though not a Yanmar - yet) I may be of some assistance to you guys.Here to exchange.Thanks for the help.Michael.
