## Definition

a type of small boat engine that hangs outside the boat. It is usually powered by a gasoline engine and is easy to repair.

For teachers: a small internal-combustion engine mounted on the stern of a boat, typically used for propulsion. Often used in the plural to refer to the engine itself.

## Examples

- The boat has a powerful outboard engine.
- Because the outboard is located on the back of the boat, it is easier to maintain and repair than an inboard engine.
- While inboard engines offer a more streamlined design, many recreational boaters prefer the outboard for its simplicity and the ability to quickly replace the unit if it fails during a trip.
