It is unlawful to operate a motorized watercraft or personal watercraft on any waters in the city unless it is equipped with a muffler or other similar device or water baffling system to reduce the sound of exhaust. It shall be unlawful to remove, disable, bypass, or use a cutout device on any muffler, muffling device or water baffling system of any watercraft or personal watercraft. Outboard engines, due to exhaust design, do not require additional muffling. (Ord. 938 §6, 1992; Ord. 454 §3, 1977; Ord. 427 (part), 1976).
