Inboard Engines: Inboard propulsion systems for marine vessels. There are several types of engines available for marine use. These can be inboard engines or outboard motors. They can be electric motors or gasoline (petrol) or diesel internal combustion engines.

There are several types of engines available for marine use.  These can be inboard engines or outboard motors.  They can be electric motors or internal combustion engines.  Internal combustion engines are either gasoline (petrol) or diesel powered.  Gasoline engines can be either carbureted or fuel injected.

An inboard motor is an engine that is enclosed within the hull of the boat, connected to a propeller (prop) or a jet pump with an impeller.  This is sometimes called a stern drive or inboard / outboard drive.  An inboard drive with propeller propulsion will have a gearbox and a leg that has a drive shaft connected to the propeller.  The skeg at the bottom end of the leg also acts as a rudder when the engine is not running.  With a jet drive the pump with the impeller is connect to the engine and swivels to provide steering.
