Attwood Marine 4140-4 Waterbuster Cordless Bilge Pump

The Attwood Marine Waterbuster Cordless Pump is a versatile submersible pump designed to remove unwanted water from boats, pool covers, aquariums, and sump pits. This portable pump operates without the need for electrical outlets, making it ideal for use in locations where AC power is unavailable or unsafe.

Key Features:

• Battery-powered operation using three alkaline D-cell batteries (not included)
• Runs continuously for up to 5 hours on fresh batteries
• Lifts water up to 40 inches vertically
• Pumps approximately 360 gallons per hour at maximum efficiency
• Fully submersible design with automatic float switch activation
• Compact and portable for easy storage and transport
• No electrical cord needed—safe for wet environments

Perfect for emergency bilge pumping, draining pool covers after rain, emptying window wells, or removing water from small flooded areas. The automatic float switch turns the pump on when water reaches a certain level and shuts off when the water is removed, preventing dry running and extending battery life.
