decible test at loto
Hey guys and gals just wanted to blow some steam off. Went to loto for the weekend and brought the new boat. Police try to run us down but frankly I wasnt goin got stop til we were in calmer water. They claim our boat was 86 dcb from a run by test. We are running merc 700s with gattling mufflers. We have been told these are legal. Next was the transom test what a joke 300 boats going by as they are taking the test 91dcb never the less we recieved a nice scratch from the police boat and a warning. Way to get people to want to come when business is down 50%. The police should worry about real problems on the lake like the rental companies who allow idiots to drive boats without training. Or there own driving skills. LOL done complaining. Weather was great! the Cove was naked as usuall and I meet some new great people. Cant wait till shootout! maybe they will let us take the tampons out for the race.

86db while running is legal??????? WTF???? 91 is just slightly over the limit.
You are not the first person to get damage from a WP boat. I know of 2 other people. One got paid and the other didn't.

Its 86db at 50 feet or more away and 89db at idle at 3 feet behind the transom.
I've been stopped running and was at 89db.
Correction, its 90db at idle.

You're lucky, Michigan law is 75db.

“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.

The law they enforce here in western Michigan is 90db
I was out with a friend this week to get his boat tested with new turn downs
Cops ticketed him for 102 db before the modification and 96 after the mods
He was trying a version that still allowed some blow by and that is why he is still above the DB but now is modifying to get the last little approved
the marine patrol was testing 90 db and below to be approved
By the way the ticket is $189 all other cival infractions are less cost with one exception (BUI) even improper boating is a lesser fine
