Does anyone have the particulars on how MP does sound tests? I have seen tidbits of info on line and am curious to the process. One article I saw stated at idle, 50 feet away, another stated at idle without specifying. Some state it is a moving test, others state it is stationary...It seems about as clear as mud.

One also mentioned that you have 7 days to submit for testing yet I talked to someone the other day that was forced by a MP officer to take it immediately (the boat was found to be in compliance).

I have recently picked up a rather loud boat and immediately added what I believe to be appropriate sound suppression to it but want to know the rules just in case I ever encounter an issue.
