Abstract
Cooling systems and methods for hybrid marine propulsion systems are disclosed. A first cooling circuit is arranged to convey raw cooling water through an internal combustion engine and to at least one drive component of a drive unit for the marine propulsion system. A second control circuit is arranged to convey raw cooling water through an electric motor. The system is arranged such that raw cooling water in the second cooling circuit is conveyed to the first cooling circuit to cool the drive component without cooling the component of the internal combustion engine.
