§ 93.046 MUFFLERS; EXHAUST; GAS.
   (A)   No person shall operate or cause to be operated any boat or craft equipped with a motor or internal combustion engine, regardless of whether the motor or engine is temporarily or permanently attached to the boat or craft, on any of the waters of the reservoir unless the motor or engine is equipped with an efficient muffler, in good working order and constant operation so as to prevent excessive noise and annoying smoke.
   (B)   No outboard motor or internal combustion engine shall be deemed equipped with an efficient muffler unless the exhaust gases are discharged under the water or are so muffled as not to be noisier or more annoying than an internal combustion engine of like power equipped with an underwater exhaust.
   (C)   No inboard motor or internal combustion engine shall be deemed equipped with an efficient muffler unless the exhaust gases are condensed and silenced by the continuous circulation of water through the exhaust pipe, or are muffled so as not to be noisier or more annoying than when condensed and silenced by water circulating through the exhaust pipe of an internal combustion engine of like power.
   (D)   No person shall use on any boat or craft on the waters of the reservoir a muffler cutout or any device that operates to discharge exhaust gases of any motor or engine without the gases passing through an efficient muffler.
