    STATE LAW REGULATING MOTORBOAT EXHAUST NOISE LEVELS IN EFFECT
    Complaints from other boaters, lake users impetus for change in state law
    Before 1994, Kansas boating laws required motorboats with above-water exhausts to have a muffled system and motors with exhaust stacks to have water-induction systems to reduce noise. The law was difficult to enforce, and when the boating laws were rewritten, the regulation on noise was left out.
    However, legislation was passed two years ago that readdresses the issue of motorboat noise levels. K.S.A. 32-1120, which went into effect on state waters January 1, 2007, states that “the exhaust of every internal combustion engine used on any motorboat on the waters of the state shall be effectively muffled by equipment so constructed and used as to muffle the noise of the exhaust.” Muffler is defined as “a sound suppression device or system designed and installed to abate the sound of the exhaust gases emitted from an internal combustion engine and which prevents excessive or unusual noise.”
    The law specifically states that motorboats shall not be operated on the waters of this state under any condition or in any manner whereby the motorboat emits a sound level in excess of 86 decibels on the “A” weighted scale, when measured from a distance of 50 feet or more from the source of the sound. The standard for measuring sound levels was adopted from those prescribed by the Society of Automotive Engineers.
    Kansas’ standard is consistent with boat noise level laws in other states, including Missouri, Colorado, Oklahoma, and Iowa and was put in place to protect the recreation interests of all boaters and lake users. Exhaust noise is the number one cause of complaints against noisy boats and was the impetus for the new law.
    So what does this mean to boaters? Most pleasure boats expel exhaust gases through the propeller hub and won’t be affected. By expelling the exhaust below the water’s surface, the problem of noise is eliminated as the water acts as a natural muffler.
    However, boats with above-water exhausts are up to four times louder than those with sub-surface exhaust systems. Consequently, these boats must have some form of exhaust muffling. The law prohibits operating a motorboat on state waters if it is equipped with an altered muffler, muffler cutout, muffler bypass, or any other device that continuously or intermittently bypasses the muffler system or that reduces or eliminates the effectiveness of the muffler system. The law does not apply to motorboats officially registered and competing in or while on trial runs 48 hours preceding a regatta, race, marine parade, tournament, or exhibition that has been authorized or permitted by the Kansas Department of Wildlife and Parks (KDWP).
    There are several different types of add-on muffling systems available that would still allow high motor performance while keeping noise within the state’s legal standards. All boaters are responsible for ensuring their boats are in compliance. KDWP law enforcement officers, using special sound measuring equipment, may request boats to submit to an onsite test to measure noise level.

    So they pass a law.
    Do they have the proper number of officers to enforce it?

    Great link for information on your state....
    http://www.cpperformance.com/TechTip...noise_laws.htm
    Also, in MN the law states 86 decibals for stationary test at 50 feet and 84 decibals at 50 feet while moving......Now keep in mind your boat has to have been manufactured prior to 1982 for these stated limits..... after 1982? Your screwed....84 and 82 respectivly for those unfortunate souls..
    If you don't drive like a mad man and bother people the local police are usually cool.....Heck I raced the local PD's Seadoo Jet boat and the guys were cool as can be.....

    It's the guys with the new Baja's or similar boats ruining it for us few hot rod boat guys. These off shore guys run these huge boats, 50 laps around the lake, with open exhaust, in many cases, the boats too small, for the lake. Another issue is they are 20 yards, or so, off the shoreline doing it, all day, and every day. When do you see Jet boats, or flat bottoms run all day, round and round? We make our cruise, do our passes and generally hang out, not seeing if we can get an other tenth of a mph over 68, with ten peeps in the boat. Most of the time we don't get bothered, just get the eye, and a thumbs up.

    Enforcement? I don't know about holiday weekends and up north, but I'm thinking IL has no money to pay DNR officers. In fact I haven't seen a DNR officer anywhere near here in two years. We went camping for two days at a nearby state park a while back, we tried to find somebody to pay for our campsite and never could.

    Wouldn't a noise violation require a running boat???

    Not really, I often float around the lake in a canoe while screaming at the top of my lungs just to annoy the fishermen
