    GPRXP Waterbox

    Forgive my lack of knowledge on the subject, but this is my first watercraft type project. That being said Is it required that I use the special made gprxp waterbox? I ask because I am putting 4tec's in a boat, and space is not an issue for me, and the fitment will not match my hull anyway, since it has a different exhaust location than a GPR. I would prefer to use the waterbox/exhaust that is already in the boat, for simplicity's sake. If I can plumb it, is this acceptable? Or is there another reason that I am missing for using the special made waterbox? Thanks!

    You should be fine running the exhaust thru the existing water box.

    What does the intake to the waterbox look like on your boat? Is it that large GPR 6" opening, or something more like a standard waterbox?
