Ordered 2 of the Shoreline Marine 800 GPH Bilge Pump with Auto Switch. Fortunately, I tested one before removal and installation. Water only drains down to 1.5 inches, leaving the bilge wet. No float adjustment. If any water drains back through the hose, it will cycle constantly. No instructions - only a wire diagram.
