“Outboard Engines” fills the gap between owner’s manuals that don’t even tell you how to change a spark plug and professional shop manuals that detail how to do a complete rebuild. It covers basic principles and techniques for a wide variety of outboards (four-stroke as well as two-stroke) with the emphasis on maintenance and advanced troubleshooting. Ed Sherman’s clear explanations and diagrams take you step by step through the basics and beyond, helping you track down even the most elusive problems a modern outboard can throw in your way. His methodical approach can save you a world of frustration and peril, as well as time and-a-half weekend mechanics’ charges.
