Originally it was intended to fit the 700 nhp Napier engine from the iron-frigate Simoom, but it was decided that as St Jean d'Acre was a new ship, they would order a new engine. She was therefore fitted with a 600 nhp Penn two-cylinder horizontal single-expansion trunk engine. The cylinders were 70.75 in diameter, with a stroke of 3.5 ft. On her Stokes Bay trials on 3 December 1853 the engine generated 2,136 ihp.

In May 1854 she formed part of the Allied Fleet serving in the Baltic against Russia in the Crimean War. In 1855, she joined the fleet in the Black Sea. On 7 July 1855 Captain George King

She was reclassed as a 99-gun ship in 1862 and 81-guns in 1863.

She was sold to Castle's shipbreakers at Charlton in January 1875, and broken up October 1875.
