Just tested my F 35-7 for decibel
Just tested the boat today. Idle around 1000 rpm, I got between 92 and 95 decibels roughly 3 feet away and 3 feet high from the silent thunder platform. Engine are 454-485 HP.
Still Not low enough to run on Lake Georges! Maybe I could be closer to 90 decibel with a idle of 750-800... |

Do you stilll have the Silent Thunder box under the platform??
Or are you trying to get away without it |

Jeff , Come down to the Hudson River for a ride . Don,t need mufflers yet. I would like to show you the lower Manhattan area. Or leave the boat home and ride with me and the wife. I to am thinking mufflers for next year. But don't want to lose any ponies from them with the newer boats getting faster with less hp.Can you beleave a 35 Lighting with 525's at 103 . Chit thats fast.

Or are you trying to get away without it Silent thunder is on it. I just thought I'd be under 90, because when I compare with other that only has muffler that are under 90, mine sound/feels way more silent then mufflers... And I still don't see how I could use muffler added to the silent thunder platform ??? |

As far as muffler goes, we are not in a bad position here in quebec generally speaking, but it not too far down the road, like anywhere else! Anyboby here on that board added muffler on a silent thunder platform ??? |

In Ohio, I've been told to have the ODNR test only one at a time for better noise compliance...................... :rolleyes: |
Re: Just tested my F 35-7 for decibel
another good point! But I think they must try to catch us up on 2 engines! More chances to make money giving tickets! But I'll try to find this info!

There is NO sound level testing ordinances in Canada, just a muffler law. Your silent thunder unit counts as a muffler, you are perfectly legal in Canada.
