Kasco De-Icers circulate water to melt ice and prevent its formation in your boat's slip.De-Icers can be hung from a vessel, dock or other flotation device and positioned to move warmer water from a deeper channel to the shallower area where your boat is moored. This helps to protect your boat and dock from lifting damage due to ice jacking” and the shearing and crushing damage caused by ice expansion.Motor assemblies are sealed in an oil bath for long life, and feature ball bearings for smooth operation. All exposed metal is non-corroding stainless steel. Each assembly includes a power cord designed for low temperatures, zinc anode for corrosion protection and a grounded three-prong plug. Optional thermostat/controller cycles De-Icer automatically to save energy.
