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.
One of
the best books on marine diesels to appear in some time.--Ocean
Navigator
The most
up-to-date and readable book weve seen on the subject.--Sailing
World
Even if
you never intend to put a spanner near your engine, and know your
mechanics home phone number by heart, this book deserves a place
on any diesel-powered boat.--Motor Boat & Yachting, London
Clear,
logical, and even interesting to read.--Cruising World
