3-12. Marine Drive System
a. Description. The marine drive system consists of two independent drive systems that are controlled separately by marine gear
control valves (4, sheet 1, fig. 2-1) in the cab. The marine drive system on the starboard side is basically the same as the port
marine drive system. Due to the opposite arrangement of the two systems, some of the components are left- and right-hand
equipment. Each marine drive system consists of fluid and flexible couplings, a gathering box, vertical drive coupling, marine gear,
jack-shaft, propeller shaft, and propeller(fig. 3-18). The forward and aft engines on each side are connected through drives to the
gathering box. Each drive has a fluid coupling located between flexible couplings. The gathering box is a bevel gear type reducer
having two input shafts and a single output shaft. The -input shafts are connected to the bevel gearing
