Sealant around exhaust

[Flying Low 2]

Hello, I'm a new owner of a 2103 SX210. The other night I installed a garmin fish finder. During my time under the boat I noticed a bit of sealant at the exhaust. I gave it a little tug just hoping to pull the loose part, instead a big, nearly circular chunk came free.

I am now thinking of putting some 3m sealant / adhesive around the exhaust. Thoughts? How concerned should I be?

If it looks something like this:

No worries, leftover of a manufacturing process.
