Abstract: A portable circulation de-icing system is configured to melt ice from a body of water having a surface ice layer and an underlying water layer, with an opening in the surface ice layer which may have been created by a user. The portable circulation de-icing system comprises an agitator assembly, a floating motor assembly, and a flexible drive shaft. The agitator assembly is configured to be at least partially placed into the underlying water layer through the opening. The agitator assembly is configured to induce a water flow into the underlying water layer. The floating motor assembly is configured to float on the underlying water layer in the opening and to provide rotational power. The flexible drive shaft is configured to transfer the rotational power from the floating motor assembly to the agitator assembly.
