A marine propulsion system (10) for marine vessel (2) includes at least one battery (30) configured to power a vessel load (35), a plurality of marine drives (11, 12, 13), and a control system (40). Each of the plurality of marine drives (11, 12, 13) includes an engine (16, 17, 18), an alternator (21, 22, 23) driven by the engine (16, 17, 18) to charge the battery (30), and a propulsor (26, 27, 28) selectively driven by the engine (16, 17, 18) to propel the marine vessel (2). Each of the plurality of marine drives (11, 12, 13) is configured to operate in a propulsion mode in which the engine (16, 17, 18) is operated to rotate the propulsor (26, 27, 28) to propel the marine vessel (2) and in a generator mode in which the engine (16, 17, 18) is operated to charge the battery (30) while the marine vessel (2) remains stationary. The control system (40) is configured to select a subset of the plurality of marine drives (11, 12, 13) and then to operate the subset of marine drives (11, 12, 13) in the generator mode to charge the battery (30) while the marine vessel (2) remains stationary.
