A ships propeller shaft transmits mechanical energy from the main engine to the propeller. When there is more than one transmission element, the propeller shaft is a kind of shafting line.
The main function of the propeller shaft is to turn the propeller. It can also be used to drive an alternator to produce electricity.
One end of the propeller shaft is connected to the vessel's main engine, the other to the propeller. As it rotates, it turns the propeller, moving the boat forward.
The distance between the engine and the stern tube will determine the length of the propeller shaft.
