Another Good book Suggestion
In addition to the Nigel Calder book on diesel engines that Dan recommended, I heartily recommend Nigel Calders book titled, Boatowner's Mechanical and Electrical Manual, This covers a variety of other boat systems that you need to know and learn about. It also has a section on Diesel engines.It covers things like battery chargers, marine electronics, transmissions, propellers, shaft, stuffing boxes, strut, cutless bearing, rigging, plumbing and water systems, and much more. The book lists for $49.95 but on sale at West Marine sometimes.Wayne Estabrooks s/v Wind Drift
