ンスト防止装置。 In a 4-stroke outboard motor with a supercharger, a valve part opens and closes in response to the differential pressure between the intake passages before and after the supercharger, and during deceleration, the valve part opens and injects air into the intake passage, thereby stimulating the engine. What is claimed is: 1. A device for preventing engine stalling during deceleration of an outboard motor with a supercharger, characterized in that it is equipped with an air injection valve for improving an overrich state of the air-fuel mixture supplied to the engine.
