If you own a small marine diesel engine that you depend on�at least occasionally�this book was written for you. Nigel Calder, a diesel mechanic of many years experience, a good writer, and perceptive teacher, has written a guide that is clear, logical, and acutally interesting. A boatowner born with a monkey wrench in his hand will find Marine Diesel Engines useful and agreeable; a mechanical illiterate will find it a godsend. Here, in nine extensively illustrated chapters is everything you need to keep you diesel engine running cleanly and efficiently�saving you a world of frustration, discomfort, and even peril, not to mention time-and-a-half weekend mechanics charges.
