S/t thru transom tips with flappers wanted
 

I find myself needing the silent thunder thru transom tips with flappers. Anybody have any removed and laying around?
I am modifing a non s/t platform (y-pipe style) to a thru the platform tips, bottom side of the platform on the sloped surface.
I will actually need another set for the platform, i am thinking 30* flange and angle cut short tips.
Anybody else do this? Any experience much appericiated.
Thanks in advance.

I am currently modifying my swim platform as well. I have a silent thunder but want to run the exhaust straight through to tips. Teague marine said they could make me whatever I needed. If you don't find anything else give them a call.

[ATTACH=CONFIG]537431[/ATTACH]Is this what you are looking for. They were removed from a 2001 Formula 35.

No he's looking for the older rectangular tips. Your best bet might be to pick up a platform that someone has for sale. Check the swap shop or go through older posts. You might just get lucky.

Gary, this is what I did in the platform, just a little different[ATTACH=CONFIG]537440[/ATTACH][ATTACH=CONFIG]537441[/ATTACH][ATTACH=CONFIG]537442[/ATTACH]

Thanks for the responses.
What i am looking to do is try to go straight out from thru-transon straight back thru swim platform with round. Hoping to land on flat surface. Possibly using 2 sets. One for transom, one for swim platform. Make sence?
Nobody done this?

Mohawk, did you get an idea of where the straight thru tips will land (exit location) on platform? Is it on the flat 30* section on the back. Thank you.

To be clear, after re-reading my original post it should say "standard swim platform" wanting to modify to thru-hull exhaust while keeping platform. Do not want to modift to rectangular exits. Want straight thru or as close as possible.
Sorry for any confusion.

This is how I'm doing it.

"Formula "Silent Thunder" modification???"

That is it. Exactly what i want to do.

looks like you started with std platform, what was lurking inside platform?
Any mods to platform, stuff inside to be removed, modified, etc?
Did yours have the o-ring gaskets between platform and transom originally?
How did you handle the seal on the outside of platform?
How far out did the pipes extend beyond the platform?
How did you get the angle correct with the posterboard and get both of them the same?
Gmgearhead454,
did you get yours done?
Any pics?
What did you use?
Mohawk,
any additional info advice from you?
Did you start with s/t?
Tip selection?
Pics?
Thanks all, it's all going to come together somehow.

I haven't started so I haven't really figured it out. I will be replacing the flappers at the transom and buying 8" long tips. I may try to order a custom tip or get it in pieces. My silent thunder platform is currently cut in half because I had some rot. It should be a little easier for me to work with. My boat currently has snow up to the rub rail so I probably won't get to it for a while.

Can you use any of this?

Gary I got a set of Hardin tips with flappers laying around they fit with the platform on 100 plus shipping . Pm me if ya want em I have 2 242's

Thanks for the offers. I have purchased mine, went with IMCO 12.5" outside boat with both internal and salsbury flaps. Bit the bullet and went new, (Thank you Eddie Young) I decided to not go with S/T concept but rater a unique look for the boat. Almost done w/project need to find somebody with a water jet to make 2 ea. S/S beauty rings so I can seal the platform-exhaust and get S/M risers to Young Performance for O2 bungs and Dry to almost tip mods.

I have the factory thru hull tips and the tips from the S/T Platform if anyone wants them. The platform is going to the dump at the end of the month.

Do you have the ladder?

Nope, she's living the dream on the back on TomZ Formula.

I habe my complete silent thunder box off and not going to ever use it, came off my 419 formula would that help you at all??

I also have a set of external tips with internal flappes for sale also

Gary, thats great the project is coming along don't forget to share pics.

I should get the transom rigging done this weekend. The engine needs to get the carb fine tuned while still on the run stand and final cheek for water leaks after raw water pump was rebuild. Hope to get engine installed next week time/weather permitting. Mark, I will send pics to you later this weekend.
Thank you and Happy Easter.
