Kasco offers a variety or replacement parts to keep your de-icer running like new.De-Icer Dock Mount:Kascos heavy duty dock or piling mount is made from corrosion protected galvanized steel (above the water) and stainless steel (in-water parts). It offers you flexibility of adjusted angle, depth in the water and 360Ëš positioning. This dock mount can be used with any of Kascos de-icer units. The de-icer unit may be extended down from the surface mounting bracket to a maximum length of 10'. You supply between 1' and 10' of 1" O.D. pipe, depending on how deep you want to suspend the unit.Replacement Propellers:For maximum efficiency, the propeller on your De-Icer must be free of damage. Propellers are designed to sacrifice themselves if debris gets inside the de-icer cage, protecting the motor from damage. We recommend keeping a spare propeller on hand.De-Icer Replacement Anode:Sacrificial zinc anode protects De-Icer from galvanic corrosion.50' Replacement 120V AC Power Cord:Fits 1/2hp and 3/4hp 2400 and 3400 models.
