The oscillating steam engine, built by John Penn & Sons, is located aboard the famed paddle steamer Diesbar. Diesbar is the second oldest of a fleet of nine paddle steamers in Dresden. What makes the Diesbar unique is its coal fueled engine and single deck design. The John Penn and Sons engine that runs the steamer is the oldest operational marine steam engine in the world. It has been in operation for over 165 years.

This outboard motor, designed and built by Ole Evinrude (1877-1934) at the Evinrude Motor Company in Milwaukee, Wisconsin, was quickly accepted by the boating public of the United States. Bess Evinrude called the prototype a "coffee grinder," but it moved a boat through water better than the huge steam- or foot-driven motors available in 1907. She encouraged him to build and sell ten, then twenty, soon resulting in the redirection of their automotive equipment business to outboard motors.
