EXHAUST MUFFLERS

The manufacturers of recreational boats are required to construct boats using efficient muffling devices (the use of cut-outs are prohibited). State laws prevent the use of boats without efficient muffling devices, and many states require the devices to prevent noise levels at established decibel ratings. Boat operators should always maintain muffling systems that prevent unacceptable noise levels.

In Virginia, the exhaust of every internal combustion engine used on any motorboat shall be effectively muffled by equipment so constructed and used as to muffle the noise of the exhaust in a reasonable manner. The muffling device shall exhaust at or below the water line or it shall be equipped with mechanical baffles. The use of cutouts is prohibited, except as approved by the Department or the U.S. Coast Guard.
