Is the center drain plug the only plug?

[Raobrien]

I recently bought a 2004 X80 with dual mcx's. I am currently fixing some issues on the boat. The main problem I have at the moment is I pull my drain plug (center) but any water accumlating in the engine compartments will not travel forward to the drain. I can not see a rear drain plug in the compartment or on the hull. What am I missing? Any help is greatly appreciated.

Thanks
