A marine drive has a supporting frame, an electric motor configured to power a propulsor for generating a thrust force in water, and an electrical power unit for the electric motor which is coupled to the supporting frame. Operation of the electrical power unit generates heat that is transferred to the supporting frame. A cowling encloses the electrical power unit and covers a first portion of the supporting frame. A different, second portion of the supporting frame is exposed to atmosphere outside the cowling. The supporting frame and cowling are configured so that the second portion of the supporting frame provides a heat exchanger that transfers the heat from the electrical power unit to the atmosphere.
