AN ARRANGEMENT FOR MUFFLING THE EXHAUST SOUND OF A BOAT MOTOR

摘要

The exhaust gases of a boat motor are led to a buffer chamber (6) with the intention of lowering exhaust sound. The buffer chamber is located beneath the waterline of the boat and is mounted on a trim tab (3) fitted to the transom (1) of the boat. The bottom of the chamber (6) is formed by the trim tab (3) and includes a slot (12), which extends transversely to the direction of water flow. A flow casing (13) through which exhaust gases exit into the water is provided beneath the slot (12).
