A marine vessel propulsion device includes an engine, a propeller shaft, a drive shaft that is rotated by power transmitted from the engine, a dog clutch that transmits rotation of the drive shaft to the propeller shaft, and an engine load generating unit. The engine load generating unit detects relative rotation speed between the drive shaft and the propeller shaft, and generates an engine load opposite in phase to the relative rotation speed detected therebetween.
