"It's not the fixing that is so hard, it's finding out just what needs fixing." The person who can do this is called a technician. The technician has put in hours upon hours of study to gain a thorough knowledge of the product and has developed an understanding of principles of operation. The technician approaches each mechanical or electrical problem as a challenge, systematically testing to determine the extent of repairs needed. With a good attitude toward the customer, honest repair practices, and technical studies, you can acquire the skills for making outboard repairs. For the student outboard technician, this manual explains the technical theory of operation necessary to prepare for training and certification at a factory training center. Reading this manual will be profitable because the basic understanding you gain will help you troubleshoot outboard systems. With greater understanding of electronic systems, such as OptiMax and Ficht Fuel Injection, you will be able to make accurate repairs that meet emission control requirements. The novice mechanic should use this text in conjunction with a factory service manual. First, read the theory in this text that relates to the repairs to be made. Then, with the aid of the factory service manual for that outboard, make the repairs, applying the theory learned. This text makes following the technical repair procedures given in the service manual easier to understand because you will know what must take place in the outboard at the completion of repair. And this text will help clarify the reasons behind the technical instructions given by the outboard manufacturer.Stagner, Eugene W. is the author of 'Understanding the Outboard Motor', published 2002 under ISBN 9780130943187 and ISBN 0130943185.
