General:
* Wake: This is the most common and general term. It refers to the trail of disturbed water left behind a moving object.
* Wash: Similar to wake, but often used to describe the turbulent, churning water at the surface.
* Turbulence: A more technical term describing the irregular and chaotic flow of water caused by the propeller.
* Churn: This implies a vigorous, swirling motion of the water.
* Whirlpool: If the propeller creates a strong vortex, this term may be used.
More specific:
* Prop wash: This term specifically refers to the disturbance caused by the propeller itself.
* Cavitation: This refers to the formation of vapor bubbles in the water due to the propeller's rapid rotation. It can be a sign of a problem with the propeller or the boat's speed.
Figurative:
* Ruffle: This suggests a milder disturbance, like ripples on the water's surface.
* Boil: This implies a more vigorous disturbance, with the water appearing to be bubbling or boiling.
The best word to use will depend on the specific context and the degree of agitation you want to describe.
