If my aerator pump was leaking how much water could it let in the boat? The bottom housing where the cartridge latches in has a few cracks in it. I hope this is my problem because its leaking a good amount of water over a 8 hour time span. I have just bought this boat and I think the previous owner did not take real good care of it. My bilge pump also keeps blowing fuses. I am thinking that he had water in this boat over the winter and the pumps froze up and cracked. Any ideas on the bige as well? I could not find any bare wires where it could be shorting out, this boat is an 06 so its not that old just had not been taken good care of.
