🔍 Key Concepts

• Fixed-pitch propeller behavior when directly coupled to a diesel engine • What control you actually have over engine speed and direction in a direct-drive system • Difference between changing propeller pitch and changing shaft rotation

💭 Think About

• In a direct-drive, fixed-pitch setup, what happens to the propeller whenever the engine crankshaft is turning? • If there is no mechanism to change the blade angle (pitch), what are your options to reduce thrust all the way down to zero? • Which choices describe actions that are only possible when you have controllable-pitch propellers or clutches, and which describe something you must do with a directly coupled, fixed-pitch arrangement?

✅ Before You Answer

• Verify whether a fixed-pitch propeller can have its pitch changed from the bridge or engine room. • Check if a direct-drive slow-speed diesel normally uses ahead/astern clutches at all, or if reversal is done another way. • Decide which option actually results in no rotation of the propeller shaft in this specific arrangement.

Both the ahead and astern clutches must be disengaged.

The propulsion clutch must be disengaged.

The engine itself must be stopped.

The propeller must be brought to zero pitch.
