A propulsion apparatus includes a screw, a unit case, an anti-cavitation plate, a heat generation portion, and a cooling liquid passage. The screw is submerged in outside water and generates a propulsion force. The unit case accommodates at least a power transmission mechanism which transmits power from a drive source to the screw. The anti-cavitation plate is arranged on the unit case at a higher position than the screw, and at least part of the anti-cavitation plate is submerged in outside water. The heat generation portion is arranged at an inside or an outside of the unit case. The cooling liquid passage causes a cooling liquid to flow to the heat generation portion. Part of the cooling liquid passage is arranged within the anti-cavitation plate.
