(2)  For the purposes of this section, "muffler" shall mean 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.

(3)  It shall be unlawful for any person to operate, or permit the operation of, any motorboat on the waters of the state of Idaho in such a manner as to exceed the following noise levels:

(a)  For motorboats manufactured before January 1, 1995, a noise level of 90dB(A) when subjected to a stationary sound level test as prescribed by SAE J2005;

(b)  For motorboats manufactured on or after January 1, 1995, a noise level of 88dB(A) when subjected to a stationary sound level test as prescribed by SAE J2005.

(4)  It shall be unlawful for any person to operate, or permit the operation of, any motorboat on any lake or reservoir of the state of Idaho, which is more than five hundred (500) feet in width, in such a manner as to exceed a noise level of 75dB(A) measured as specified in SAE J1970. Provided, that such measurement shall not preclude a stationary sound level test as prescribed by SAE J2005.

(5)  No person shall operate, or give permission for the operation of, any motorboat on the waters of the state of Idaho that is equipped with an altered muffler or a muffler cutout, bypass or other device designed or so installed so that it can be used to continually or intermittently bypass or otherwise reduce or eliminate the effectiveness of any muffler or muffler system installed in accordance with the provisions of this section.

(8)  The provisions of this section shall not apply to motorboats registered and actually participating in an authorized marine event, or to a motorboat being operated by a boat or engine manufacturer for the sole purpose of testing and/or development.

(9)  Any peace officer who has reason 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. If such motorboat exceeds the decibel levels established in this section, the officer may direct the operator to take immediate and reasonable measures to correct the violation, including returning the motorboat to a mooring and keeping the motorboat at such mooring until the violation is corrected or ceases.
