Can anyone post some pics of b4 and after. I assume a 89' 311 comes with the same set up. I was looking into to purchasing a 311.

I don't know how to post pics here but after wet sanding and adding new Hardin Marine exhaust tips the boat looks great!!! I do miss the added length the platform gave it so I will be adding a new one once I decide on exactly who I want to make it.

Can't beat the sound without the silent thunder though!!!

So is the swim platform just a hollow chamber that muffles the sound or is there some kind of baffling in there. If either case couldnt straight pipes be added in from the transom to the end of the platform?

Yeah, that is kind of the idea. There is a fiberglass chamber in there that holds water and muffles the exhaust. You can cut through it with a hole saw and make up some custiom pipes if you wanted. It has been done. There is even a thread here about doing it. But the exhaust ports on the platform are far from being just straight in line with the exhaust on the transom!!!!

Besides, these platforms are big, ugly, and heavy. In my opinion, and again it is my opinion, Silent thunder platforms are garbage.

Newer formulas have an integrated platform with the silent thunder box bolted under it. When removed you still have the platform. Way better design!!!!

Ditched mine three years ago on the 311....wow!...what a difference. Got my platform from extreme machine. Awesome quality! But big $$$$ Call me if you have any questions, it was a rather involved project restoring the transom. 217-246-4411 Tyler

My transom is looking great after alot of work and elbow grease!!! And I mean alot!!!

Do you have any pics of your boat with the new platform?

What did that run you if you don't mind me asking?

I'm pulling my ST box off as well? Anyone recommend a good place to get the rubber exhaust flapper cheap?
