what is an outdrive engine on a boat?

There are three ways to identify how a boat is propelled. Outboard = engine and drive all in one unit, hangs from stern, easily removable. Inboard = Engine mounted inside the boat, connected to a transmission, which has a shaft that goes through the bottom of the boat that the propeller is attached to, steered using a rudder. Inboard/Outboard = The engine is mounted inside the boat, the drive unit, or transmission, is mounted on the outside and is also used to steer the boat by turning left and right. On an inboard/outboard, or I/O as they’re called, the unit on the outside of the boat is called the outdrive. On the outdrive, the upper unit is attached to the engine through a flexible coupling, the lower unit is where the propeller is attached, and the transmission, or directional gears, are in between.
