The Adlard coles book of maintenance and repair for outboard motors

AS WITH MOST TECHNICAL THINGS on a boat, the outboard engine is simple to use but can seem obscure and complex as soon as it breaks down. However, on taking a closer look and with a bit of guidance, all can become clear. That is the aim of this book. It explains engine technology in simple terms, with drawings that allow you to visualise how it works.
The best way to avoid engine breakdown is by carrying out regular maintenance. With a little guidance, a task that appears tedious and time-consuming can in fact be relatively quick and easy. The maintenance and repair worksheets in this book are designed to allow beginners as well as the mechanically knowledgeable to work on their outboard engines with confidence. All these tasks, whether maintenance or repair, are explained with precise illustrations showing the steps for each procedure. All the tasks are coded as either simple, technical or complex depending on your level of skill and experience.
The book is divided into four parts. The first covers the technical elements of outboard engines. The second part contains maintenance/repair worksheets that will allow you to maintain your engine efficiently. The third section reviews the most common causes of engine breakdown. A troubleshooting list allows you to diagnose and fix the most common outboard engine problems. Finally, the fourth part reviews the different steps to follow in one of the most important maintenance routines: winterising. Designed along the same lines as the step-by-step maintenance/repair worksheets, this chapter will show you how to winterise your engine in one short afternoon.
