🔍 Key Concepts

• Identify the power flow from the engine to the output shaft by tracing which gears are in constant mesh in the illustration. • Consider how a typical reversing reduction gear works: usually clutches select ahead or astern while the main gears stay meshed. • Look closely at the clutch arrangement on the input shaft and pinions: which parts appear fixed, and which could actually move or rotate?

💭 Think About

• From the picture, count the number of gear meshes between the input and the output. Does that look like a single or double reduction? • Ask yourself whether, in normal marine gear designs, the ahead pinion is physically moved out of mesh when going astern, or whether engagement is done some other way. • Examine how the ahead and astern clutches are mounted: are they likely to transmit engine power to both pinions, or to slide axially to pick up different gears?

✅ Before You Answer

• Verify whether any gear in the illustration appears to slide out of mesh when reversing, or if all gears look permanently meshed. • Check if there are two distinct stages of speed reduction (double reduction) or just one large bull gear driven by pinions (single reduction). • Confirm which components are clearly driven directly by the engine shaft and which are on the pinion shafts; this will help you test the statements about the clutch glands and how the clutches engage.
