Keith:

     You might try bathtub caulk to seal the penetrations.  However, if
you've accumulated that much water in the box, I would recommend you include
provisions to drain it.  A couple of small (quarter-inch) holes in the
bottom of the box should do it.  You can find screening material to apply
across the opening; the material will keep critters from establishing a home
inside the box.
