This 15cc single-cylinder, water-cooled model boat engine is an OHV (overhead valve) 4-stroke designed to burn gasoline on a magneto spark ignition. It was manufactured in England in the 1960s. The crankcase, cylinder, head and flywheel are from cast aluminum, and the internal parts are machined from bar stock. The crankcase holds oil for lower end lubrication and a small amount of oil is added to the gasoline for upper end lubrication. The engine is 7″-long, 6.5″-wide, 8″-high, and weighs 4 lbs. 11 oz.
