(a) A motorboat shall not be operated on the waters of this state under any condition or in any manner whereby the motorboat exhaust noise emits a sound level in excess of 92 decibels on the “A” weighted scale, when subjected to a stationary sound level test as prescribed by SAE J2005.

(b) The provisions of subsection (a) shall not apply to motorboats officially registered and competing in or while on trial runs 48 hours immediately preceding a regatta, race, marine parade, tournament or exhibition which has been authorized or permitted by the department.

(c) Any officer authorized to enforce the provisions of this section who has reasonable suspicion to believe that a motorboat is not in compliance with the noise levels established in this section may direct the operator of such motorboat to submit the motorboat to an on-site test to measure noise levels, with the officer on board if such officer chooses, and the operator shall comply with such request. The owner of any motorboat which violates any provision of this section shall have sixty days from the date of the violation to bring the motorboat into compliance with the provisions of this section. Thereafter, it shall be the owner’s responsibility to have the motorboat tested by the department. If the motorboat fails such test, the motorboat shall not be operated on the waters of this state until the department certifies that the motorboat is in compliance with the provisions of this section. Failure to comply with a request or direction of an officer made pursuant to this subsection is a class C misdemeanor. Nothing in this section shall be construed to limit the officer’s ability to enforce this section and to issue citations to the owner or operator of any motorboat during the sixty-day compliance period.
