The exhaust ports at the side of my 405 Carver are leaking. The starboard side seems impossible to get too. The leaks seem to be coming from where the fascia joins the elbow just inside the hull. I have tightened up the clamps which did not seem to be loose at all but that did not help. Has anyone experienced this kind of issue with a 405 or 406? Even information on other cavers would also be helpful as I imagine I'm not the only person to find this kind of problem. Thanks. Joe
