Friend has a 2000, 271. Exhaust/water is leaking all around the Silent Thunder box where it bolts up to the bottom of the platform. Do we need just a peripheral-type seal for this or are there "donut" gaskets inside like my older style 311 paltform?

Thanks.

There are seals around the exhaust tips where they exit the transom and a perimiter seal where the platform and transom meet.
Talk to Magicfloat hes a Formula dealer. He can get the seals for you.

When you friend pulls the platform have him check for rotting wood in the platform. Common problem.

Are you sure about the rotting wood thing Iggy? It's a 2000, didn't think there was any wood in the later models.

tell him to get rid of it and buy a pair of used Corsas or the like. They are plentiful as take-offs cheap/reasonable. No more box hassles, and that 271 could really benefit from the weight removal from the stern! Not to mention easier cleaning.

Hey Rip, how you doin'?
He's not gonna go for tips, wants it stock. Do you have an answer to my question seing how you removed yours totally?

Platform is all glass. I have the donuts in stock.

Sounds good Magic. So, it uses a peripheral gasket or seal around the box AND a set of donuts around the tips just like the old-style SR1 platforms, right?

No,only donuts

Just sent you an email Magic.

Since you didn't say what year the boat was I assumed it was an older model with the bolt-on platform. Not a 2000 with a molded in platform.

Sorry.
