Which component connects the motor to the impeller in a watercraft?

The drive shaft is the component that connects the motor to the impeller in a watercraft. Its primary function is to transmit power generated by the motor to the impeller, which then propels the vessel through the water. The drive shaft allows for the transfer of rotational energy, enabling the impeller to spin and create thrust. This connection is crucial for the functionality of the watercraft, as it directly impacts acceleration and speed.

The steering nozzle directs the flow of water for steering but does not connect the motor to the impeller. The safety lanyard is a safety feature that ensures the motor stops if the operator falls overboard; it does not play a role in the engine-to-impeller connection. The transom is the flat surface at the rear of the boat where the motor is mounted, but it does not facilitate the mechanical connection between the engine and the impeller.
