Abstract
A marine propulsion device includes an engine, an exhaust passage, a porous body, a retainer mat, and a stopper portion. The engine includes an exhaust port. The exhaust passage connects to the exhaust port. The porous body is disposed in the exhaust passage. The retainer mat covers the outside peripheral face of the porous body. The retainer mat retains the porous body. The stopper portion is disposed inside the exhaust passage. The stopper portion is disposed downstream of the porous body and spaced apart from a downstream-side end portion of the porous body. The stopper portion extends inwardly in the radial direction, past the outside peripheral surface of the porous body.
