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.
