I saw here that the Water Mota Sea Scout MK 2 was ''based on'' the Lehman 2712E, does that mean they are the same engine? I had called Water Mota and they said they do not have anything to do with these engines any more, they referred me to Stevensons Marine but they do not answer either of their phones or reply to my emails, the same for American Diesel. The boat is in the Caribbean and I want to have my engine rebuilt completely so I need the parts for this and the manuals, does anyone have any ideas?
