A watercraft propulsion unit includes an engine body, a throttle body, an intake passage, and a resonator. The throttle body is configured to supply air to the engine body. The intake passage is connected to the throttle body on an upstream side of the throttle body. The intake passage includes an intake inlet to draw in the air and an intake outlet to guide the air to the throttle body. The resonator is connected to the intake passage to reduce an intake sound of the air. A volume of an internal space of the resonator is greater than a volume of an internal space of the intake passage between the intake inlet and the intake outlet.
