A vessel propulsion apparatus includes a water pump that is driven by an engine, and supplies water from an water inlet to the engine via a cooling water supply passage. The vessel propulsion apparatus includes an auxiliary cooling passage branching from the cooling water supply passage to extend to an oil pan. A water pressure control valve disposed at a branch position from the cooling water supply passage to the auxiliary cooling passage limits the flow rate of water flowing to the auxiliary cooling passage when a water pressure inside the cooling water supply passage is less than a set pressure. The water pressure control valve is configured to allow a portion of the water inside the cooling water supply passage to flow to the auxiliary cooling passage when the water pressure inside the cooling water supply passage is the set pressure or more to maintain the water pressure to be less than the set pressure while supplying water to the oil pan via the auxiliary cooling passage.
