Kasco Water Circulator delivers reliable, efficient performance to protect your boat, dock or other property from costly ice damage and helps prevent winterkill situations with your fish. De-icers push warm, bottom water to the surface to prevent or eliminate ice formation. Designed for continuous duty and salt water applications, this de-icer will thrive in even the harshest environments, thanks to its stainless steel and thermoplastic components. The oil-cooled motor is more efficient than air- or water-cooled versions and offers superior longevity and lower electrical costs. Comes with two 20ft. ropes for suspension below docks. Includes 50ft. power cord. Horizontal floatation kit (#108697) and dock mount accessory (#108698) sold separately. Other cord lengths available.
