As long as I got a stainless steel bolt with some nuts and metal washers I'm not sure what would be...

    Carb Gasket(s) question

    Hi, I received two gaskets for the carb when I ordered a new manifold. Am I meant to be using both of them? The old gasket is compressed and broken so I'm not sure what was there before. I've attached a picture showing the 2 new ones. I have a 2005 Mercruiser 3.0L serial: 0W601238...
