<p>Boat propeller transmission with a horizontal input shaft (1), a bevel gear set (3, 4a, 4b), a vertical intermediate shaft (5), an additional bevel gear set (30, 31, 32), and at least one horizontal propeller shaft. Between the bevel gear sets, a two-speed planetary gear set (9) is engaged, to provide two gear speeds in the same direction between the input shaft and the propeller shaft. A control unit (40) controls the shifting between the low and high gear speed. A sensor (42) senses the position of a gear selector (41). 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.</p> |
