A picture would be worth a 1000 words. Post one and somebody will be able to tell you. It depends on the size and location of the bunge as to what its for.
What can you do with it??? If its not broke, don't try and fix it, you might break something.

if it goes all the way through the inner and outer pipes its for a 02 sensor,if it just goes into the outer pipe then it for relieving pressure at the tip..you would pit a barbed 90* fitting in the hole and use a through transom fitting to plumb the water out of the boat..mainly for reversion purposes..
