A little help needed - drainage side compartments

[MM33]

Hey Guys,

Upon opening my side compartment hatch on the port side I noticed that there was about 10 gallons of water there with no where to go. Do you know how those side comparments drain?
I opened the other side comparment hatch to get a better view (no cables and wires blocking my view) of the drainage system and noticed a rubber tube. That appears to be how it drains into the bilge. Can anyone confirm this? Maybe the tube it obstructed by a cable on the other side.
Any tips on how to fix this would be greatly appreciated.

My boat is a 1984 23' CC

Thanks guys..
