A marine propulsion device has an internal combustion engine, an exhaust manifold that conveys exhaust gas from the internal combustion engine, and a cooling water sprayer that is configured to spray a flow of cooling water radially outwardly toward an inner diameter of the exhaust manifold. The cooling water sprayer has a sprayer body that is configured to convey the flow of cooling water radially into the exhaust manifold and a nozzle configured to spray the flow of cooling water radially outwardly in a fan-shaped pattern toward the inner diameter of the exhaust manifold.
