Transmission systems and methods are for a marine propulsion device having an internal combustion engine that drives a propulsor. An input shaft is driven into rotation at a non-zero first rotational speed by the internal combustion engine. An output shaft drives the propulsor into rotation at a non-zero second rotational speed. A planetary gearset transfers power from the input shaft to the output shaft. A band brake is on the planetary gearset. Actuation of the band brake effects a gear change in the planetary gearset. A band brake actuator actuates the band brake to effect the gear change. A controller controls the band brake actuator. Based upon one or more operational characteristics of the marine propulsion device the controller is programmed to control the band brake actuator so that the second rotational speed is less than the first rotational speed.

An outboard motor having an internal combustion engine that causes rotation of a driveshaft and a planetary transmission that operatively connects the driveshaft to a transmission output shaft, the planetary transmission being operable in a forward gear in which forward rotation of the driveshaft causes forward rotation of the output shaft, a reverse gear in which forward rotation of the driveshaft causes reverse rotation of the output shaft, and a neutral gear in which rotation of the driveshaft does not cause rotation of the output shaft, a band brake configured to shift the planetary transmission amongst the forward gear, neutral gear, and reverse gear, and a hydraulic actuator configured to actuate the band brake.
