Maurice, Not sure which website you are looking for. American Diesel, who marinize the current Ford Lehmans is at http://www.eaglesnest.net/americandiesel/. There is a company called Mermaid - Northeast Engines that has a Lehman maintenance manual section of their website. The main site is at http://www.northeastpower.com/index.htm and the maintenance info is at http://www.northeastpower.com/maint1.htm. Steve Williford DF44 Cloud Nine Oak Harbor, WA
