An outboard engine is a type of motor used to power boats. It is mounted on the outside of the boat's transom, which is the flat surface at the back. Outboard engines are popular because they are easy to install, maintain, and can be removed for storage or repairs. They come in various sizes and power levels, making them suitable for different types of boats, from small fishing vessels to larger recreational crafts. These engines typically use either gasoline or electric power. The design includes a propeller that drives the boat forward and a steering mechanism that allows the operator to control the direction. Outboard engines are often favored for their versatility and efficiency, making them a common choice for both recreational boating and commercial fishing activities.
