Is there a new law that requires mufflers on airboats?
Technically there is no “new” law. Florida law (Chapter 327.65, Florida Statutes) has required every vessel operated in Florida to have their engine exhaust effectively muffled in a reasonable manner for many years. Flex-pipe had been widely accepted as a form of “muffling device” for airboats, but no work had been done to determine its effectiveness. Recent scientific research concluded that flex-pipe alone is ineffective as a muffling device, therefore it cannot meet the legal requirement for effective muffling without the addition of a device designed to muffle engine exhaust sound.
