This Seachoice bilge pump switch is serious marine equipment that could save your boat from taking on water. It's an electromagnetic switch with a non-clogging design that works reliably in tough marine environments. The automation is brilliant - it turns your bilge pump on when water reaches 2-1/4 inches deep and automatically shuts it off when the water drops to 3/4 inches. The 15-amp maximum capacity handles most bilge pumps, and the 12V DC operation works with standard boat electrical systems. It comes with a universal mounting bracket and 6 feet of 16-gauge tinned wire that resists corrosion in saltwater environments. The false-start protection prevents unnecessary pump cycling, which extends your pump's life. It's NMMA, ABYC, and Coast Guard certified, plus it comes with a solid 36-month warranty and is 100% factory tested. Installation is straightforward whether you're replacing an old switch or adding automatic bilge protection for the first time. For boat owners, this is one of those essential safety items that gives you peace of mind knowing your bilge will automatically handle any water intrusion even when you're not on board. The quality is professional-grade without the professional price tag.
