Outboard Engines 2nd Edition: Maintenance, Troubleshooting, and Repair — by Ed Sherman
Four-stroke outboards and exotic, computer-controlled fuel-injection systems have become mainstream. What hasn't changed, however, is that proper maintenance and an intimate knowledge of the inner workings of your outboard are prerequisites for trouble-free boating and maximum engine longevity..
Outboard Engines 2nd Edition fills the gap between owner's manuals that don't even tell you how to change a spark plug and professional shop guides that detail how to do a complete rebuild. It covers basic operating principles, maintenance procedures, and troubleshooting techniques for two- and four-stroke engines from 2 to 300 horsepower.
With Ed Sherman's help, you'll be perfectly capable of performing your own engine maintenance, repairing minor problems, and diagnosing problems you can't tackle yourself. His methodical approach can save you a world of frustration?and peril?as well as time-and-a-half weekend mechanics' charges.
