I have a 2004 sportfish. Neither live well aerates. If I leave the live well pump running, is the overflow tube big enough to prevent overtopping the livewell? If not, would adding a livewell drain tube in place of the livewell plug be enough to handle the water along with the regular live well overflow? The plug is 1", and I tried a 1and 1/8 tube once and it wouldn't fit, and I don't see 1" tubes anywhere. Should I just force the 1 and 1/8th? I'd really like to keep my fish alive for as long as possible.
