I just got a 2015 22ft. SC. On the starboard side there is a black cap that covers a threaded port with a screen in it. I have gotten several and varied answers as to what it is from dealers. It is close to the head waste drain. Anyone have any idea as to what it is and if I need to use it for something? Thanks.

    An owner of a similar boat might be able to identify it for you, posting a picture of it helps others to help you that don't have your model.
