Final answer:
A tiller is used for steering on small boats and is a lever attached to the rudder. Larger ships in the past used tillers but now mainly use more complex steering systems. The propulsion mechanism, which could be propellers or nuclear-powered turbines, provides thrust but does not dictate the steering method.
Step-by-step explanation:
The type of engine that uses a tiller for steering is typically found on small boats. A tiller is a lever attached directly to the rudder, which is used to steer the vessel. In the past, larger ships also used tillers before the invention of the ship's wheel, but in modern times, the term usually refers to the steering apparatus on small watercraft.
Whether a ship uses a tiller or a more complex steering system does not depend on the type of propulsion mechanism alone, such as propellers or nuclear-powered turbines. Both propellers and turbines can be components of a ship's propulsion system, with the rotating turbine shaft or propeller shaft providing the necessary force to move the ship through water. Nevertheless, the choice of steering system is more related to the size and function of the vessel rather than its engine type.
In cases where a ship runs aground and tilts, requiring torque to be applied to return it to an upright position, the steering mechanism may be secondary to other equipment and procedures designed to correct the ship's orientation.
