ABSTRACT:
An improved exhaust pressure pulsation control apparatus for a marine propulsion system has a front ring, a reflector disk located downstream of the front ring, and a plurality of connecting members connecting the front ring to the reflector disk. Each connecting member has a concave outer edge to facilitate mounting the apparatus within an exhaust tube. A clamp outside of the exhaust tube clamps the exhaust tube against the concave outer edges of the connecting members to secure the apparatus longitudinally within the exhaust tube. The apparatus is preferably made of a fiberglass reinforced thermoplastic material, such as 33% fiberglass reinforced polythalamide or nylon 4,6, through an injection molding process.
