Mufflers and Noise Level Limits
Vessel operators may not hear sound signals or voices if the engine is not adequately muffled.
- The exhaust of every internal combustion engine on any vessel must be muffled effectively. That is, the engine’s exhaust must be muffled or suppressed at all times so as not to create excessive noise.
- The use of cutouts is prohibited, except on racing boats competing in approved marine events.
