    Functional and acceptable quality for a budget system

    I was already breaking the bank on my system so I opted for the inexpensive vent/drain thru hulls. Quality is decent and blends in nicely especially on a black boat.

    There was a bit of a "burr" from the molding process on the barbed ends of all of these that restricted the internal diameter noticeably. Not sure what kind of affect that would have on the flow but I opted to ream it off. A step drill bit turned by hand took care of it pretty easily.
