MUFFLERS AND NOISE LEVELS
Every motorboat must be equipped with an effective muffling device. Some muffler cutout devices may be approved by the Commissioner of the DEEP. A law enforcement officer may direct a suspected offender through one of the tests to determine noise levels. Fines for refusing the test are substantial.
No person shall sell a boat that does not operate in compliance with the established noise levels.
Connecticut noise levels are as follows:
Engines manufactured before January 1, 1993 90 dBA
Engines manufactured on or after January 1, 1993 88 dBA
