    just realized you cant really see what I was talking about. It is on the starboard side, front of header. I circled it with a yellow circle.

    Rotten headers? Weep holes for the water injection are usually much lower and between water n head

    Dare to be different, if it turns out great you can claim you planned it that way.

    yeah the weep holes are all there. someone was inquiring on a craigslist ad and asked if it was for an o2 sensor. I love my boat cause im not a full blown mechanic and its easy as hell to work on. even with my lack of knowledge im pretty sure its not for an o2 sensor. it is about a 1 inch hole just above the elbow and it has a threaded plug in it.

    Probably EGT ( exhaust gas temp) would be my guess. Someone before you may have had that to help dial in his air/fuel ratio.

    O2 sensor bung. You can buy a plug at any muffler shop.

    If it is an O2 sensor bung...with weep holes and water injection an O2 sensor wouldn't work very well or long.

    It looks too small in diameter for an O2 sensor?

    Thanks guys.
    Formula- I was thinking the same thing. That's what made me think it's not for an o2 sensor.
