Abstract
Boat propeller transmission with a horizontal input shaft, a bevel gear set, a vertical intermediate shaft, an additional bevel gear set, and at least one horizontal propeller shaft. Between the bevel gear sets, a two-speed planetary gear set is engaged, to provide two gear speeds in the same direction between the input shaft and the propeller shaft. A control unit controls the shifting between the low and high gear speed. A sensor senses the position of a gear selector. When the gear selector is in the reverse position, the control unit locks the planetary gear set in the high speed position, regardless of the engine speed.
