EXHAUST MUFFLERS

The term "muffler" means a sound suppression device or system designed and installed to abate the sound of exhaust gases emitted from an internal combustion engine and which prevents excessive or unusual noise.

The exhaust of every internal combustion engine used on any vessel shall be muffled or baffled and water injected, except those engines that exhaust through the lower unit or outdrive when the vessel is on plane, so as to decrease noise. Vessels competing in regattas or boat races may be exempt from such provisions.

The operator of any vessel, when requested to do so by any law enforcement officer authorized to enforce this title, shall submit the vessel to a noise level test.
