Notes The archetypal beginners engine from Stuart, not quite as popular as the 10V vertical version but still with many examples made. Many parts are interchangeable with the 10V. The "Score", a twin-cylinder version, is quite rare (most people who wanted to make a twin made the Double 10 which was designed for powering larger boat models).
