Abstract: A watercraft includes a hull, an engine compartment defined at least in part by the hull, an engine disposed in the engine compartment, an air intake conduit fluidly connected to the engine, an air filter fluidly connected to the air intake conduit, and a shroud connected to an inlet end of the air intake conduit located in the engine compartment. The shroud has an open end and a closed end. The open end is open to flow of air therethrough and the closed end is closed to flow of air therethrough. The shroud has a sidewall extending between the closed and open ends. The shroud is oriented such that the open end is disposed rearward of the closed end. Noise exiting the inlet end of the air intake conduit and the air filter is reflected generally rearward by the shroud. An engine assembly for a watercraft is also disclosed.

Abstract: An inlet grate for a water jet propulsion system to be used in a watercraft has a water passage having an inlet defined by a forward and a rearward area with respect to the watercraft. The inlet grate comprises a first end portion adapted to be connected to the forward area of the inlet and a second end portion adapted to be connected to the rearward area of the inlet as well as at least one elongated member extending from the first end portion toward the second end portion. The inlet grate also comprises at least one deflector having a forward end and a rearward end, the forward end being adjacent to the first end portion of the inlet grate.
