i got pulled over in flagler county and the fish cop told me that he shouldn't be able to hear the boat from 50 feet. he also told me he doesn't like loud boats. i have a 496ho mag. we have a hardin marine store(keith eickert) in palm coast. the boys there sold me the turn down mufflers. hopefully that keeps the fish cop happy. the officer doesn't even have a DB meter. he told me its up to discrestion. that aint right.
