BCB I dont know if you saw it, but RKW did indicated a 2013 model on his header. I have seen a few use those lights out in the bays down here on multiple brands but I cant say I have seen a Cat with one. But I have seen some real cruddy older boats I didnt think would float running that light around here. If the wiring harness to the front is 10-12 gauge and just the wiring from the socket to the harness is 16 gauge it should only be about 7 1/2 inches, and I dont see a where it would be a problem.
