The only book to examine the development of early marine engines with a focus on the two-cycle machines popular in the Midwest, New England, and Canada. Covers history of key companies, biographies of inventors, techonology, construction methods, material on collecting and retoring, and a list of about 800 companies throughout the U.S. and Canada that once built marine engines. This is the latest, updated of a classic title first published in 1982. Ongoing response to this book led the author to undertake a four-year project that led to the two-volume Engines Afloat, from Early Days to D-Day, which will be published in the spring of 1999.
