It provides practical guidance to undertake everyday maintenance on your diesel engine; it demonstrates how to complete a service and locate and resolve common faults; explains the theory required to understand each of the boat's main systems and shares the practical skills and techniques that engineers spend many years learning. This invaluable resource will be of great interest to those who own and run narrow boats, those starting out and more veteran boat owners.
