[HIGH-PERFORMANCE 1100 GPH FLOW RATE]: Equipped with a 3-blade impeller that delivers a higher flow rate than competing bilge pumps, this pump can efficiently and stably drain water to keep your boat dry and protected in demanding marine conditions Automatic mode connection :Contect black wire to negative,Contect brown white wire to positive,,brown no wiring.Non-Automatic mode connection :Contect black wire to negative,Contect brown wire to positive,,brown white no wiring. Install at the lowest point in your bilge where water naturally collects Ensure adequate water depth around the pump (needs to be about 3/4 submerged to prime properly) Position where the pump can be easily accessed for cleaning the snap-off strainer..Features a removable base for quick cleaning and debris removal, keeping the pump in top condition。 Keep your bilge pump in top condition with minimal effort. Level Installation : Mount the pump as level as possible - this is essential for proper float switch operation. That even a 7.5° angle can cause the float to stick in the "on" position, draining your battery. Optimal Placement Aim for less than 2° off level for reliable automatic operation. Use the removable base to mount securely to the bilge floor Consider using shims if your bilge floor isn't perfectly level Make sure it won't shift or tip during boat movement The level installation is the most important factor - many customers initially had issues until they shimmed the pump to near-level position. You'll need 1 1/8 inch marine bilge hose to connect properly. Most boat supply stores carry this standard size - look for reinforced marine-grade bilge hose that can handle the pump's 1100 GPH flow rate without collapsing. This compact unit combines a pump and float switch into one integrated solution, reducing the need for separate components. Ideal for retrofitting or new installations, it simplifies bilge water management. Equipped with built in electronic controlled reed sensor system for easy fully automatic operation.The built-in float switch activates the pump automatically when water levels rise and shuts it off when water is removed, ensuring consistent and worry-free operation.
