A marine vessel includes a hull, an engine, and an exhaust manifold including four upstream exhaust holes connected to four exhaust ports, respectively, one downstream central exhaust hole defined by two central upstream exhaust holes of the four upstream exhaust holes, two downstream side exhaust holes located downstream of the four upstream exhaust holes in an exhaust flow direction and spaced from and adjacent to the downstream central exhaust hole on both sides of the downstream central exhaust hole, and a water jacket. The water jacket is located in the exhaust manifold such that cooling water flows between the downstream central exhaust hole and the downstream side exhaust holes.
