There are three popular variations of powerplants: inboard, inboard/outboard, and
outboard.
If the engine is installed within the boat, it's called an inboard;
if it's a removable module attached to the boat, it's commonly known as
an outboard motor.
An outboard motor is installed on the rear of a boat
and contains the internal combustion engine, the gearbox, and the propeller.
An
inboard/outboard contains a hybrid of a powerplant and an outboard,
where the internal combustion engine is installed inside the boat, and the
gearbox and propeller are outside.
A purely inboard boat contains everything
except a shaft and a propeller inside the vessel. There are two configurations
of an inboard, v-drive and direct drive. A direct drive has the powerplant
mounted near the middle of the boat with the propeller shaft straight out
the back, where a v-drive has the powerplant mounted in the back of the boat facing
backwards having the shaft go towards the front of the boat then making a
'V' towards the rear.
