Abstract
A marine vessel propulsion device includes an engine, a jet propulsion unit, and a reverse gate. The jet propulsion unit includes a jet port arranged to jet water toward a rear of a hull. The reverse gate is arranged to be capable of being changed in opening degree between a fully closed position of covering an entirety of the jet port and a fully opened position of not covering the jet port at all. The reverse gate is arranged to be moved, between the fully closed position and the fully opened position, to a first partially closed position of only partially covering the jet port and a second partially closed position of only partially covering the jet port and being closer to the fully opened position than the first partially closed position.
