The donuts aren't actually attached as nothing will stick to StarBoard. They act to spread the load from the seacock/thru hull. the 3M5200 forms a gasket that seals by compression when the thru hull is tightened...

I know this is an older article but am curious as to how the starboard donuts were attached to the hull. Will the 3m provide the required seal? I am under the impression that Starboard is not supposed to be attached with adhesive.
