What is likely a consequence of using an incorrectly designated propeller?

Using an incorrectly designated propeller can lead to potential damage to the engine because propellers are specifically engineered to match the engine's performance characteristics. Each propeller has a defined pitch, diameter, and design that affects how the engine produces thrust. If a propeller that is not suitable for the engine is used, it can cause excessive vibrations, improper loading, and even lead to engine overheating due to incorrect operational parameters.

Additionally, the mismatch can result in reduced performance and efficiency, as the engine may not be able to operate within its optimal range. In extreme cases, if the propeller does not properly dissipate the engine's power or if it places too much strain on the engine components, this can lead to catastrophic failure. Properly matching the propeller to the engine is vital for ensuring both safety and reliability.
