Plugged drain

My 45cc has a plugged drain in the catch pan under the engine that drains into the bilge. I ran a wire through the engine compartment side to try to unplug it with no positive results. Does anyone know the location where the drain empties into bilge?

Thank you for your help!

I have an AC 45. The freezer, refrigerator, bilge, and engine catch all have catch drains that run to a manifold with valves for each drain. The manifold has a gulper pump. I have to open the appropriate valve and then activate the gulper pump which is connected to a hose under the flooring in the galley. None of these drain directly into the bilge. Follow the drain hoses from the engine bilge drain. Would not make sense to have an engine drain that dumps into the bilge. Let me know what you find.
