🔍 Key Concepts

• Understand what a single reduction gear unit is in a marine propulsion system • Know the role and location of the bull gear in the gear train • Know which element in a gear train typically directly engages the bull gear to reduce speed and increase torque

💭 Think About

• In a simple single reduction gear train, which part is connected to the high‑speed input (from the engine or turbine)? • Which component usually meshes directly with the large bull gear to achieve speed reduction? • Look at each choice: which are actual driving gears versus shafts or specialized mechanisms that might not apply here?

✅ Before You Answer

• Be clear on the difference between a gear and a shaft in a reduction gear unit • Visualize (or sketch) a basic marine reduction gear: input, small gear, large gear, output shaft • Eliminate any option that is not normally part of a standard marine single reduction gear train (e.g., used more in automotive or complex systems)
