Quick question I have pulled my powerhead and the exhaust cover to check that the inner baffle plate didn’t have a pinholes in it which fortunately it doesn’t.

It seemed like there were two gaskets on the inner side of the baffle plate as well as the outer side when I pulled it apart.  I checked the exploded parts diagram and it shows needing two 304762 gaskets for both item 32 outer and 34 inner on the attachment.  I want to confirm this is correct as I was always under the impression if you want something to leak install two gaskets and since these gaskets are critical to keeping the water out of the exhaust chamber is a single gasket now preferred?

There is obviously not a clearance issue in this location that I can think of so not sure why two would be needed?  Perhaps due to the heat?  Are the current versions 0f the 304762 thicker thus no longer needing two of them? If two are indeed needed what is the preferred sealer to use between them at this location.  I don’t see a lot of specifics in the Johnson Manual regarding this and want to make sure I do it correctly.  Any advice appreciated!
