- Gear is the major part of a Engine which is full fill the Rapid section of a Engine.
- Marine gears perform the essential role of transmitting power from the engine to the propeller . They also provide a smooth transition between transmitting and not transmitting engine power and between propeller rotation directions (forward and reverse), and play a role in ensuring quiet vessel operation by minimizing gear noise and vibration at low engine speeds. Together, these requirements mean that marine gears are fundamental to the functioning of the vessel. This report describes the technologies used in marine gears to provide these core functions.
