Exhaust through gasket fail, leak

[dietz]

Check those exhaust through hull bolts.

@dietz

Grabbed a wrench to check, but found this on port side. How hard of a fix? Is it. Gasket or just silicone? Guessing it has to be fixed from inside - how to get inside? Thanks in advance

I really don’t know, Someone should chime in shortly, I imagine it is Silicone but I’m not sure.

Normal. Extra Silicone

We've seen alot of pictures just like that over the years, nobody has ever reported a problem because of it,

As dough said, it's just excess,

Same boat same piece sticking out I pulled it off and put a few turns on those bolts. I did have water leaking in, not a lot but I sealed multiple different items I'm not sure exactly what the final fix was but its bone dry every time I pull the drain plug so whatever that silicone was doing on my boat had now impact on water leaking in after the bolts were tightened.

This link contains all the items that were sealed its amazing how many holes are below the water line in this boat the rub rail alone has about 40 screws with at least another 30 items between those bolts on that flange and every other component under the swim deck while at no wake mode they are all under water
