A vessel propulsion apparatus includes a propulsive force generator including a duct and a propeller. The duct includes a stator. The propeller includes a rim that includes a rotor disposed at a position facing the stator, and a blade on an inner side in a radial direction of the rim. The vessel propulsion apparatus further includes a steering shaft that turnably supports the duct, a motor controller that rotationally drives an electric motor including the stator and the propeller in forward and reverse rotation directions, a turning mechanism that turns the duct in a full turning angle range including a range of ±180 degrees, and a turning angle range limiter that limits a turning angle range of the turning mechanism 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.
