A boat motor is a mechanical device used to propel a boat through water. It can be powered by various sources, including gasoline, diesel, or electricity. Boat motors come in different types, such as outboard motors, which are mounted on the transom, and inboard motors, which are installed inside the boat's hull. These motors vary in size and power, depending on the boat's design and intended use. They are essential for activities like fishing, recreational boating, and transportation. Proper maintenance of a boat motor is crucial for ensuring safety and efficiency on the water.
