On fast sport boats with a length under 10 m (33 ft) the so-called Z-drive is frequently the mode of propulsion, which is meant to combine the advantages of inboard motors with those of outboard motors - low noise levels in combination with high maneuverability. The real drive (propeller and transmission) is located outside the boat. Generally, the connection between the engine and the transmission is made through an flexible coupling in association with a cardan shaft.
