    Is this the power head base gasket?

    1999 Mercury 200 EFI Serial: 0G939607
    There is a piece of gasket sticking out at the green arrow/circle. It is also oily around it as the pics show. I ran it on muffs and didn’t notice any water or exhaust coming out. This is basically right under the port side head.

    Unclear precisely which item you're pointing at... but that's the general vicinity of the powerhead gasket.
