Muffling Systems Any motorboat operated on California inland waters or coastal waters up to one mile from shore must be muffled or otherwise prevented from exceeding the following noise levels when measured by the Stationary Sound Level Measurement. Procedure for Pleasure Motorboats (SAE J2005):

• 90 dB (A) for engines manufactured before Jan 1, 1993. • 88 dB (A) for engines manufactured on or after Jan 1, 1993.

All motorboat noise levels must be below 75 dB (A) when measured by the Shoreline Sound Level Measurement Procedure (SAE J1970). Authorities generally agree that unbaffled exhaust pipes (stacks) do not meet any of the above noise level requirements.
