Looks like you might still have the plastic internal version and the heat finally warped them. Seems to be common and once warped they leak.
Skiers doesn't make them anymore and you will have to get 3.5 flanged exhaust fittings and do some magic. If the FAE comes with the thru-hulls or does in fact replace them, this might be your best bet. But I thought the FAE mounted to the thru hall exhaist fitting.
