the only reason i ask is that my copper tubing gets quite hot after about 15 mintues of run time. This is trroublesome because my copper tubes have to be pointed out of the vent port, and it only does that when i bend it correctly to do so. of course the tubing seems to always need readjusting, and that's when i notice it getting hot. which means that maybe more of my exhaust goes through my "relief ports" than on some other outboards. hard to tell. i will check into the neoprene at NAPA here pretty soon.
