The Sterdrive is a propulsion system for boats where the engine is mounted in the rear and faces the aft. An Outdrive is made up of a transom assembly, gimbal housing, Drive Shaft Housing, Lower unit gear housing and propeller. The engine connects to the U-Joint all working together to spin the propeller in order to move the boat forward. The most common system is the Mercruiser brand by Mercury Marine.
