I have a 1999 seafox cc. It has two compartments at the back. One on the right that fills with a switch and the switch the other way says aerator. What should this do. The tank doesn't hold water so I'm guessing I need to put a plug in it? The tank in the other side looks the same but doesn't seem to have the ability to fill unless the switch or pump is broken. Can someone tell me how this boat should work? Thank you
