Excessive noise can prevent a vessel operator from hearing signals and voices.

  • Every vessel with an engine operated on Utah waters must be equipped with a muffler system in good working order and in constant operation to prevent excessive noise.
  • No person may operate, or give permission to operate, a vessel that exceeds the following noise levels:
    • For engines manufactured before January 1, 1993, a stationary noise level of 90 dB(A), measured from a distance of 1 meter to the rear of the vessel with the engine idling (SAE J2005)
    • For engines manufactured on or after January 1, 1993, a stationary noise level of 88 dB(A), measured from a distance of 1 meter to the rear of the vessel with the engine idling (SAE J2005)
    • For all vessels, an operational noise level of 75 dB(A), measured at the shoreline (SAE J1970)
  • You may not remove or modify a muffler or muffling system if the result is increased noise level.
  • The use of a muffler cut-out or a muffler bypass system is prohibited if the engine noise levels do not meet the requirements listed above.
