Make sure you have a plug the right size to put in your livewell pump, transom hole. I was on the water Friday when I noticed water on the floor of my Bass Boat. Opened the hatch and found water half way up on my batteries. Turned on the bilge pump and started pumping, once the water got down a ways I found the leak. My livewell pump had a crack on the housing letting water in pretty fast. Managed to fish the rest of the day running the bilge pump every few minutes. If I had a plug that would have fit into the intake hole for my livewell pump I could have fixed the problem. Any break in your livewell plumbing could cause the same problem, water could come in faster than you could pump it out. My tip is make sure you have a plug the right size to put in your livewell pump, might save a fishing day or keep you afloat.
