Miscaroo had a diesel-mechanical propulsion system with four medium-speed diesel engines driving two shafts through twin input-single output gearboxes. The main engines were eight-cylinder Wärtsilä Vasa 8R32 medium-speed diesel engines rated at each. The flexible couplings in the Lohmann & Stolterfoht Model GVA 1400 SO single-stage reduction gearboxes allowed choosing between fuel-saving cruise in open water using two engines or full icebreaking power with all four engines running. The four-bladed stainless steel controllable pitch propellers, manufactured by LIPS Canada, had a diameter of and were placed in fixed nozzles. For maneuvering, the vessel had twin rudders, a OmniThruster water jet thruster in the bow and an KaMeWa tunnel thruster in the stern. Onboard electricity was produced by two Caterpillar auxiliary diesel generators or a smaller Caterpillar 3404 diesel generator which was intended to be used when the vessel is at dock. In addition, the gearboxes incorporated 1,200kVA shaft alternators.
