Dan, Grand Haven hasn't been boater friendly for YEARS!!! That's why I hardly ever go in there---Holland either! You might get away with loud exhausts during the SOTW poker run, but you can pretty much forget it any other time.
During SOTW I will be leaving from St. Joe with a few other offshore boats and head north to just beyond South Haven to watch the poker run boats come in. I have no desire to go to Grand Haven.

4 feet up from water line and 4 feet back from transom.
I caught one local trying to hold it up with his boat sitting horizontal to my transom. I pulled out the book and read it outloud to him.
He started saying this or that and I showed him the state manual.
He then proceeded to write a warning and then said 'have a nice day' why pushing away from me.
No one likes being told how to do thier job, especially law enforcement. But they also should know the rules of thier duties also.
Just be lucky that you are 'allowed' to have switchable exhaust, we here in MN and WI are not so lucky

On Lake Travis in Austin the water cops only care about one thing... Public Safety.
If you are not endangering yourself or others, you can do just about anything!
I love our water cops!

Here is the current bad news.
Cut and pasted from MCL law library
6.10 Equipment Requirements and Required Personal
Flotation Devices
A. Misdemeanor—Equipment Requirements
MCL 324.80156 details the sound requirements for motorboat mufflers and underwater exhaust systems. MCL 324.80156(1) states:
*MCL 324.80156(2) allows the DNR to establish rules for alternative sound level tests and maximum decibel levels.
“Subject to subsection (2),* a person shall not operate a motorboat on the waters of this state unless the motorboat is equipped and maintained with an effective muffler or underwater exhaust system that does not produce sound levels in excess of 90 dB(A) when subjected to a stationary sound level test as prescribed by SAE J2005 or a sound level in excess of 75 dB(A) when subjected to a shoreline sound level measurement procedure as described by SAE J1970. The operator of a motorboat shall present the motorboat for a sound level test as prescribed by SAE J2005 upon the request of a peace officer. If a motorboat is equipped with more than 1 motor or engine, the test shall be performed with all motors or engines operating. To determine whether a person is violating this subsection, a peace officer may measure sound levels pursuant to procedures prescribed in SAE J1970, issued 1991-92.” A person who violates MCL 324.80156(1) is guilty of a misdemeanor punishable by: • imprisonment for not more than 90 days; and • fine of not less than $100.00 or more than $500.00. MCL 324.80156(6). In addition, the person must install a muffler or underwater exhaust system that meets the act’s requirements before putting the vessel back in use. Id.
R 281.1238 Mufflers; cut outs.
The exhaust of all internal combustion engines used on any waters of this state shall be muffled effectively by equipment so constructed and used as to muffle the noise of the exhaust of the engine in a reasonable manner. The use of cut outs, bypasses, or similar devices is prohibited, except for vessels competing in a boat race or regatta sanctioned by the department under sections 151 and 152 of the act. A modern device, underwater exhaust system or a system discharging cold water through the exhaust of an inboard engine, each of which is capable of muffling the noise of the exhaust of the engine in a reasonable manner, shall be considered as meeting the requirements of this rule.

Here is what you need to try and beat it.
Excerpt from SAE J2500
(copied and pasted from pdf)
4. Procedure
4.1 Measurement Site—A suitable site is a body of water free of large obstructions or reflective surfaces such as
buildings, boats other than those involved in this procedure, large embankments or breakwaters, etc. for a
minimum distance of 8 m (25 ft) from the boat being measured. The boat being tested shall either be moored
to a dock or lashed to another boat. If moored to a dock, the dock shall be of open construction so that it
presents a minimum of reflecting surfaces. If the measurement is made in open water, the boat being
evaluated shall be lashed to the measurement boat to prevent relative motion and to allow positioning of the
microphone in the prescribed location. The measurement boat shall be positioned to minimize reflected
sound.
4.2 Boat Operation—The engine shall be operated at low idle speed within the engine manufacturer's
recommended operating range, in neutral gear if so equipped. For motorboats without a neutral gear, the
engine shall be operated at its lowest operational speed. The engine shall be operated for a sufficient amount
of time to allow water to flow through the exhaust system before taking measurements.
4.3 Measurements
4.3.1 The microphone shall be placed at a distance of 1.2 to 1.5 m (4 to 5 ft) above the water and no closer than
1m (3.3 ft) from the vertical projection of any part of the boat in the area adjacent to the exhaust outlet(s).
4.3.2 The meter shall be set for slow response and the A-weighting network.
4.3.3 The observer reading the meter shall not be closer than arm's length from the microphone to minimize sound
reflections.
4.3.4 The applicable reading shall be the average sound level measured during a period when the background
sound level is at least 10 dB lower than the measured sound level. Background sound level includes wind effects, noise from boats other than the one being measured, wave action, boat wakes, and other extraneous
noises.
Peak readings of intermittent sound levels created by wave slaps or changes in sound level due to
wave action and/or engine speed variation shall not be included in the applicable reading.
4.3.5 The observer shall record the applicable reading and the background sound levels taken immediately before
and immediately after the applicable reading.
5. General Requirements
5.1 The measurements shall be conducted only by persons qualified by training to perform these measurements.
5.2 Proper use of all test instrumentation is essential to obtain valid measurements. Operating manuals or other
literature furnished by the instrument manufacturer should be consulted for both recommended operation of
the instrument, and precautions to be observed.
5.3 Proper acoustical calibration shall comprise the complete measurement system including extension cables,
etc. Field calibration shall be performed immediately before and after each test sequence.
5.4 A measurement shall be invalid if changes in the background sound level affect the applicable reading.
5.5 The use of the word "shall" in the procedure is to be understood to be mandatory, while the word "should" is to
be understood as advisory.

Sorry did not get back to everyone sooner, was out of town. You all probably know by now this law is not the main issue with me like the new proposals. The "Cutouts" would not be legal on a dry exhaust in Michigan. The "Cold Water" injected exhaust counts as a muffler in Michigan. You do need to make sure you can currently pass SAE J2005 with the cutouts open at idle and the water being injected in. At speed you can open the cutouts, especially if a mile or more offshore, but you do need to leave the water injection on. Or you can say What The Hell and take your chances. Do watch out for the jail clause though!!

The LAW is the LAW, so read it very carefully, there is no where in there that it states that the microphone be placed behind the boat.
4.3.1 says 4-5 ft. above the water and no closer then 3.3ft from the vertical projection. I have heard that this is a flaw in the law the law enforcement dosn't want anyone to know.
Tell them to hold the mic 4ft in front exhaust not behind.
Again I have only heard this. So read it again and give me your opinion of the law. Where are the Lawyers when we need them.
For Boyne Thunder Poker Run we get noise restriction lifted and also the speed limit raised to 80 mph. on Lake Charlevoix. Believe me that's not easy, but we get it done.
