The Diesel Engine Manual for the Rest of Us If you were surprised to learn that your boat’s engine has no spark plugs, you’re not alone. If you’re like the rest of us, you want to know how your engine works and how to keep it working, but you haven’t come across a simple, nontechnical treatment of the subject. Until now, that is.

Developed by the Royal Yachting Association--whose seamanship courses are considered the worldwide gold standard for boating education--the book has been fully revised and adapted for North American boatowners. You’ll find: Simple yet complete information on how your engine works and the half-dozen things to check first when it fails to work as it should Easy-to-follow, step-by-step instructions for troubleshooting, maintenance, and repairs Everything powerboaters and diesel-auxiliary sailboat owners need to know to use their engines with confidence
