The first edition of Outboard Engines set the standard for a clear, easy-to-follow primer on engine basics, troubleshooting, care, and repair. This new edition, significantly expanded, brings the subject up to date, with full coverage of the new four-stroke engines, conventional electronic and direct fuel-injection systems, oil-mix systems in the new clean two-strokes, and more. You'll save time and money doing your own engine repairs and maintenance.
