MARINE DIESEL ENGINES

MAINTENANCE - TROUBLESHOOTING - REPAIR

Here, in this goldmine of a book, is everything you need to keep your diesel engine running cleanly and efficiently

Nigel Calder, a diesel mechanic of many years´ experience, explains how diesel engines from 10-100 hp work, and lifts the veil of mystery that surrounds such engines. As he says:

´There is no reason for a boatowner not to have a trouble free relationship with a diesel engine. All one needs is to set the engine up correctly in the first place, to pay attention to routine maintenance, to have the knowledge to spot early warning signs of impending trouble, and to have the ability to corect small problems before they bemome large ones`.

Clear and logical, this extensively ilustrated guide will tell you all you need to know to enable you to be your own diesel mechanic. Boatowners born with a monkey wrench in their hand will find this book immensely useful; mechanical illiterates will find it a godsend.
