What type of engines are common for boats for shallow water?

For shallow water, outboard motors and jet drives are commonly used due to their ability to operate in limited depths. Outboard motors can be raised or tilted to navigate over shallow areas, while jet drives use a water jet propulsion system, allowing boats to glide over shallow surfaces without the risk of damaging a propeller. Additionally, lightweight flat-bottomed boats often pair well with these engine types for optimal performance in shallow conditions.
