Somewhere awhile ago, in this Forum, there is a thread about a 311SR-1 for sale, and a thread about silent thunder platforms, there are photos of them in both. Probably been two, maybe three months ago, but if you look you'll find them.

I just bought a 1988 242LS and had to pull the Silent Thunder platform. Do you want know the placement of the gaskets or how to attach them?

I need to know what holds the doughnuts in place so I could match the origional set up as good as possible.
the platform on my boat had gotten hot (over heated hoses due to lack of water) and melted the back portion of the platform. trying to make sure I have as little of an exhaust leak as possible between the transome and platform.
Thanks

That was the problem with my swim platform, exhaust coming out between the platform and the transom. We pulled the platform and had to replace the wood because it rotted out. The new gaskets had adhesive on them and we centered them around the holes in the swim platform, Then the large gasket went on the platform and we reinstalled it. I bought the boat from from a friend and he did all the calling to Formula and a Formula dealer in the Detroit area to ask about the gaskets and the glue they used on the swim platform.

The gaskets that seal the exhaust tips (called donuts) do not come with any adhesive on them. They are thick, fairly heavy-duty foam rubber type gaskets. To install, you should get use regular contact cement (rubber glue). apply glue to the flat face of the donut and apply glue to the corresponding location on the board where the donuts will go. Let the glue dry then stick the donuts to the board. There is no need to glue them to the transom, the clamping force of the bolts will suck them down tight.
The peripheral gasket that goes all the way around the board does have a pre-applied adhesive. This gasket is not an exhaust sealing gasket. This gasket keeps the transom-to-board interface dry (theoretically, so the wood won't rot out). So take your time with this gasket.
If you're rebuilding your board with new wood, you should do a fit-up of the board to the transom without any gaskets to make sure you have equal space all around the edge and at the donuts. If you have any high or low spots, the gaskets will not be evenly compressed and in no time, you're right back where you started!! This is critical to doing the job right. You may find that you need to rework the back surface of the board to make it conform nicely to the transom. Remember, the transom (and the back of the board) is not flat. It has a contour to it.
If you search in this forum (Formula) section, you find much information on this topic. I have posted several times on this topic. I have rebuilt and reinstalled two silent thunder boards. One on a 242 and one on a 311. I can probably help you with any questions. Good luck and take your time,,,,,make it nice!!

Formula Outlaw What do want for your swim platform?Do you have any picks to show me? What kind of condition is it in? How come you removed it? And last, has it been modify inside for exhaust? Propwash.
