Join us for the largest marine engine show in the nation–the annual Antique Marine Engine Expo at Mystic Seaport. The transition from sail to engine power was a momentous event for the maritime industry and the world. Experience it firsthand as collectors from around the country come together to show full size and miniature 19th- and early 20th-century marine engines. Inboards, outboards, steam, gasoline, diesel, electric, and naphtha engines will all be on display in the Museum’s Henry B. duPont Preservation Shipyard. Additional engines dating from 1889 to 1963 and manufactured by Evinrude, Johnson, Herreshoff, Palmer, and Kriebel will be exhibited in the North Boat Shed.

More than 300 exhibits will be presented by over 100 exhibitors. Many engines will be operated for your viewing and listening pleasure, and a large selection of marine models will also be on display to delight the young at heart.

Weekend activities include a set-and-weigh anchor demonstration featuring a 1914 Economy Sparta donkey engine aboard the L.A. Dunton and the firing of several engines in the Shipyard, including a six-cylinder D-90 Lathrop diesel engine from the 1940s and a two-cylinder Wichmann semi-diesel from Norway. There will also be a 1917 Hercules engine demonstration behind the Museum’s Hoop Shop.
