A vessel propulsion apparatus (100) includes a propulsive force generator (40) including a duct (41) and a propeller (42). The duct (41) includes a stator (47). The propeller (42) includes a rim (51) that includes a rotor (53) disposed at a position facing the stator (47), and a blade (52) on an inner side in a radial direction of the rim (51). The vessel propulsion apparatus (100) further includes a steering shaft (43) that turnably supports the duct (41), a motor controller (86) that rotationally drives an electric motor (50) including the stator (47) and the propeller (42) in forward and reverse rotation directions, a turning mechanism (46) that turns the duct (41) in a full turning angle range including a range of ±180 degrees, and a turning angle range limiter (95) that limits a turning angle range of the turning mechanism (46) to a reduced turning angle range narrower than the full turning angle range, and when a predetermined limitation cancellation condition is met, cancels the limitation and allows turning in a turning angle range wider than the reduced turning angle range.
