The reduction in maneuverability of a hull caused by a sink vortex generated in the vicinity of a duct is suppressed. A boat propulsor includes a duct, a propeller disposed in the duct and rotatable around a rotation axis along the axial direction of the duct, and a rotation mechanism to rotate the propeller. The upper portion of the duct is provided with a plate extending from the duct in the axial direction and having a plurality of holes formed therein. In this boat propulsor, the plate is provided to extend from the upper portion of the duct, and the plate is provided with a plurality of holes formed therein. Multiple water streams coming around along the duct are attenuated as they pass through the holes in the plate.
