Silent Thunder rattle?

Chris · 06-20-2006, 04:09 PM

What is up with the rattle of the platform. It acutally vibrates the back seat a little bit. I like the looks and sound of the silent thunder, just not the vibration.
Can this be fixed or cured without removing the silent thunder?

Chris .. the baffles have been known to come loose ... I dont think you can repair them without taking the box off .... Some have gone in thru the rear outlets and cut a dog house type opening in the baffles ... like upside down "U" ... there are two baffles on each outlet... just a partition in the box ... one from the top ending about 4" from the Bottom and one from the bottom ending 4" from the Top .... the exhaust has to ~ to get out ...mine was broke loose on the Baffle closest to the transom. My Glass guy used a putty to repair it .. worked well ... Since then I have removed the box again and cut out ALL the partition, but have not run it yet. m

Mine rattles too. It is loose where the top and bottom are joined together (behind the rubrail). Had to put a couple of screws in to help quiet it it down. Others have said it's due to the baffles coming loose inside the platform. I took mine out and it still rattled. Seems the only sure way to get rid of the rattle is to remove the platform completely

What year boat is your silent thunder on? The older ones pre 1990 are more of a pain to repair then the newer ones.

Mine is a 1991. Will the boat sound much different if I remove the baffles?

Yes, It will sound better, I did this on my 272 sr1 and it gave it a nice rumble, you can do asearch on silent thunder and find the thread that tells you how to do it, I did mine by drilling 3 holes in the top 2 corners and the middle top of the baffle, and then used a keyhole saw, to cut across and then down to cut them out, it is easier to get the piece out by cutting it in half to get it back out thru your exhaust opening, Some people have also used a sawzall, but i found it easier with the keyhole saw, mine had a 12" blade.
