Motorboat
A motorboat or speedboat is a boat which is powered by an engine (also commonly called a motor). Some motorboats, especially those used for water skiing, may have two engines. Some motorboats are made with inboard engines built in; others attach an outboard motor containing the internal combustion engine, the gearbox and the propeller in one portable unit.
An inboard/outboard contains a hybrid of a powerplant and an outboard, where the engine is installed inside the boat, and the gearbox and propeller are outside.
