The Frisco Standard 1/4 scale marine engine was built by Ron Schindele, of AZ, in 2013. This is a 1/4 scale model of the 16 HP 2-cylinder Frisco Standard, built by the Standard Gas Engine Company of San Francisco, CA in the early 1900s. The original engine had a 6.25 bore and 7.5 stroke with a maximum running speed of 325-405 revolutions per minute. Though normally run on gas, Ron designed his model to burn propane with a 6V igniter ignition. It is an alternate firing engine however, the second cylinder fires 180 degrees after the first creating an unusual cadence while in operation. Frisco Standard engines were made in marine, hoisting, or stationary type engines, but they were most commonly used as marine engines.
