A marine propulsion device includes an entry suppressor extending circumferentially between an inner peripheral surface of a duct and an outer peripheral surface of a rim in a radial direction of a rotor to reduce or prevent entry of foreign matter into a gap between the inner peripheral surface of the duct and the outer peripheral surface of the rim. The entry suppressor has a thickness larger than a minimum width of the gap and smaller than a maximum width of the gap in the radial direction of the rotor.
