 Enterprise had a Ravenhill, Salkeld & Co. direct-acting horizontal single-expansion 2-cylinder direct acting steam engine driving a single propeller. Steam was provided by a pair of tubular boilers. The engine produced 690 indicated horsepower (510 kW) which gave the ship a maximum speed around 9.9 knots (18.3 km / h; 11.4 mph). Enterprise carried 95 long tons (97 t) of coal. As built, her funnel was mounted in the middle of the battery for protection, which impaired the working of her guns until it was relocated forward of the battery in November 1864. She was barque-rigged with three masts and had a sail area of 18,250 square feet (1,695 m2). Her best speed under sail and steam was 9.8 knots (18.1 km / h; 11.3 mph).
