Period cutaway diagram of a triple-expansion steam engine installation, circa 1918. This particular diagram illustrates possible engine cutoff locations, after the Lusitania disaster and others made it clear that this was an important safety feature. A marine steam engine is a steam engine that is used to power a ship or boat.
An outboard motor is a propulsion system for boats, consisting of a self-contained unit that includes engine, gearbox and propeller or jet drive, designed to be affixed to the outside of the transom. They are the most common motorised method of propelling small watercraft.
With both inboards and stern drives there is a fire and explosion hazard from gasoline fuel vapors within the engine compartment. Typically these boats must run a blower for several minutes prior to starting the engine, and when idling or moving below cruise speed. The blower exchanges the air within the engine compartment with fresh outside air.
V12 marine diesel engines . Human-powered paddles and oars, and later, sails were the first forms of marine propulsion. Rowed galleys, some equipped with sail, played an important early role in early human seafaring and warfares. The first advanced mechanical means of marine propulsion was the marine steam engine, introduced in the early 19th ...
An inboard motor is a marine propulsion system for boats. As opposed to an outboard motor, where an engine is mounted outside the hull of the craft, an inboard motor is an engine enclosed within the hull of the boat, usually connected to a propulsion screw by a driveshaft. Marine diesel engines used in international shipping are the largest ...
SS Humboldt Engine Room, illustrated in Harper's New Monthly Magazine, No. XII, May 1851, Vol. II. Steamship generally refers to a larger steam-powered ship, usually ocean-going, capable of carrying a (ship's) boat. The SS Humboldt engine room, to the right, is a concept drawing during the construction of the ship. The term steam wheeler is ...
The Deltic-powered Hunt-class mine countermeasures vessel HMS Ledbury. Development began in 1947 and the first Deltic model was the D18-11B, produced in 1950. It was designed to produce 2,500 hp (1,900 kW) at 2000 rpm for a 15-minute rating; the continuous rating being 1,875 hp (1,398 kW) at 1700 rpm, based on a 10,000-hour overhaul or replacement life.

An engine order telegraph or E.O.T., also referred to as a Chadburn, [1] is a communications device used on a ship (or submarine) for the pilot on the bridge to order engineers in the engine room to power the vessel at a certain desired speed.
