A marine propulsion device (100) includes an entry suppressor (60) provided circumferentially between an inner peripheral surface (40a) of a duct (40) and an outer peripheral surface (51a) of a rim (51) in a radial direction of a rotor (54) and configured to reduce or prevent entry of foreign matter into a gap (G) between the inner peripheral surface (40a) of the duct (40) and the outer peripheral surface (51a) of the rim (51). The entry suppressor (60) has a thickness (t) larger than a minimum width (W1) of the gap (G) and smaller than a maximum width (W2) of the gap (G) in the radial direction of the rotor (54).
