The muffler may not be modified or altered, such as by a cutout. The department may require a test at dockside to determine exhaust noise level.(b) The provisions of subsection (3)(a) do not apply to a motorboat or vessel: (i) competing in a state-sanctioned regatta or boat race while on trial runs between 9 a.m. and 5 p.m. and during a period not more than 48 hours immediately preceding the regatta or boat race;(ii) operating under a separate permit issued by the department for the purpose of tuning engines, making test or trial runs, or competing in official trials for speed records other than in connection with regattas or boat races; or(iii) operated by an authorized agent of federal, state, or local government to carry out the duty of enforcement, search and rescue, firefighting, or research.(4)(a) Except as provided in subsection (4)(b), a vessel may not be equipped with a siren, and a person may not use or install a siren on a vessel.(b) An authorized emergency vessel may be equipped with a siren capable of sound audible under normal conditions from a distance of not less than 500 feet, but the siren may be used only when the vessel is operated in response to an emergency call or in the immediate pursuit of an actual or suspected violator of the law, and the operator of the vessel shall sound the siren when necessary to warn persons of the vessel's approach.(5) When in operation or at anchor or moored away from a docking facility between sunset and sunrise, all vessels must display lights as prescribed by the department.(6) The department may designate waters where and the time of year on these waters when all persons aboard a motorboat or vessel shall wear approved life preservers at all times.(7) Vessels, including houseboats and floating cabins, equipped with a galley or toilet must have a wastewater holding system sealed to prevent the discharge of water-carried waste products, whether treated or untreated, into the surrounding waters.(8) The department may adopt rules modifying the equipment requirements contained in this section to the extent necessary to keep these requirements in conformity with the provisions of the federal navigation and safety laws or with the navigation and safety rules promulgated by the United States coast guard.(9) A person may not operate or give permission for the operation of a vessel that is not equipped as required by this section.En.
