Which component is responsible for delivering power to the propeller?

The component responsible for delivering power to the propeller is the lower unit. This part of an outboard motor houses the essential gear mechanisms that convert the rotational power generated in the engine into the rotational thrust that drives the propeller. Inside the lower unit, you will find the drive shaft, which transmits the engine's power, along with gears that adjust the rotational speed and direction before it reaches the propeller. This critical mechanism ensures that the boat can move efficiently through the water.

The other components mentioned, such as the cylinder head, mid-section, and steering bracket, serve different functions. The cylinder head contains the combustion chamber where fuel and air mix and ignite, while the mid-section provides the structural integrity of the motor and connects the engine to the lower unit. The steering bracket, on the other hand, is primarily involved in steering control, allowing the operator to maneuver the boat effectively, but it does not play a role in power delivery to the propeller.
