The problem isn't the level, it's enforcing it. Straight pipes on boats are illegal to. You can make the laws to reduce these levels, they need a better way to enforce it. Like they do with cars, at safety inspections. These sound levels need to have a consistant way of testing them to make them useful. Granted people still get away with these things but the inpection stations are at least a start. I'm surprised the state hasn't figured out that there's money to be made with inspection stickers for boats....then again...it's just a matter of time!
