Well, that is a different story....<GRIN!>
I doubt that your CB cable outlet is leaking then. Forgetting the bilge drain plug will definitely fill the bilge with water! I forgot that once, thankfully I checked the bilge before leaving hte ramp......and then saw the plug sitting in hte cockpit! Normally, I screw it in while painting the bottom of the boat since my boat stays in hte water for the season, that way I KNOW it is in.... but that year....well ,I must have forgotten it! Thankfully, as I say... it was still out in hte cockpit and I was able to reach over the transom and screw it in, then pump out the water. The pic below shows the 2 critical plugs, well actually only the bilge plug is "CRITICAL", but both are important as is the one for the cockpit self-bailer. Some boats have the bilge draim off-center, about where the "X" is in my pic.
