A marine hybrid drive unit (100) has an electric motor (2) and a transmission (3). The transmission (3) has an input shaft (4), an output shaft (5), and a pressure actuated transmission clutch (6) configured to selectively connect the input shaft (4) to the output shaft (5). The input shaft (4) can selectively be driven solely by a combustion engine (1), solely by the electric motor (2), or by both the combustion engine (1) and the electric motor (2) simultaneously. The transmission (3) further includes a main oil pump (7), driven by the input shaft (4) to provide oil pressure for actuating the pressure actuated transmission clutch (6). An auxiliary oil pump (8) provides oil pressure to the pressure actuated transmission clutch (6) during operation in a low-speed range. Also disclosed is a method for driving such a marine hybrid drive unit.
