Re: Went to the boat for a sail..and its Flooded!!!
Hard to tell from your photo, but looks like your bilge pump wiring might be getting wet. If the spice connections are not 100% water tight this will lead to corrosion and failure of the wire. You mentioned the + lead broke loose. Stray current will also lead to underwater metal corrosion (electoloysis). Try to make your pump/float switch connections well above high bilge water level to the connection never gets wet.
