Abstract
A shutter valve construction for the exhaust system of a marine engine that discharges exhaust underwater. The valve construction includes an adaptor having an annular body that is adapted to be engaged in the end of an exhaust pipe. Opposite sides of the body are provided with outwardly projecting bosses which are received within holes in the exhaust pipe to position the adaptor relative to the pipe. The valve construction also includes a butterfly-type shutter valve that consists of a pair of valve members which are hinged to a hinge pin that is removably connected to the adaptor. To connect the valve to the adaptor, the ends of the hinge pin extend into opposed openings in the body of the adaptor and receive resilient grommets.
