Abstract: The invention relates to a marine-vessel transmission having an input-drive shaft (10), which extends along an input-drive shaft axis (A) and on which an input-drive shaft gearwheel (12) is arranged, a first pinion shaft (14), which extends coaxially with respect to the input-drive shaft (10) and on which a first pinion (16) is arranged, a second pinion shaft (24), which extends parallel to the input-drive shaft (10) and on which a pinion shaft gearwheel (28), which engages with the input-drive shaft gearwheel (12), and a second pinion (26) are arranged, an intermediate shaft (18), on which a spur gear (20), which engages with the first pinion (16) and the second pinion (26), and a bevel pinion (22) are arranged, and an output-drive shaft (30), which extends along an output-drive shaft axis (P) which runs at an angle (?) of more than 75° with respect to the input-drive shaft axis (A), and on which a spur bevel gear (31) is arranged, which forms a bevel drive with the bevel pinion (22).

Abstract: A drive including a fixed housing, a shaft rotatably disposed in the housing, at least one hydraulic-fluid actuatable switching element, a supply of hydraulic fluid to the actuatable switching element, an inner body disposed on the shaft so as to co-rotate with the shaft and including an annular groove and a floating seal disposed between the fixed housing and the inner body. The supply of hydraulic fluid includes a feed channel that extends from radially outside through the fixed housing so as to discharge in the annular groove and extends inside the inner body to the hydraulic-fluid actuatable switching element.
