Mufflers and Noise Level Limits
All vessel engines must be equipped with an effective muffling device. Vessel operators may not hear sound signals or voices if the engine is not muffled adequately, and the noise is irritating to other people.
The use of any type of exhaust cutout that allows exhaust to bypass the engine muffling system is prohibited.
Muffling an airboat's exhaust with automotive-style mufflers is required in Florida.
