The Skylark 2-cycle marine engine was designed and built by Gerald Smith, of the UK, in the 1980s. Mr. Smith manufactured over 300 engines from 1922 to the mid-1980s. Of the fourteen 10cc Skylarks that he built, only 3 were water-cooled for marine applications. He designed and produced his own magneto, castings, spark plugs, carburetors, and timers, and then furnace enameled the parts for the finishing touches. This two-stroke engine burns gasoline on spark ignition.
