A gearbox is a set of gears that provides a controlled application of a power transmission system. The gears provide speed and torque conversions from a rotating power source and transferring energy from one device to another. This provides high transmission efficiency. However, marine gearbox does not have much in common with the gearbox of a car. Most marine gearboxes have only one set of gear hence one ratio other than the ZF which makes a two-speed marine gear. Secondly, the clutch is inbuilt. The marine gear has three functions. It engages and disengages the engine from the propeller and provides reverse rotation. The other use is setting the ratio between engine rpm and propeller rpm. This means that even used marine gearboxes have an automatic gearbox design.
