ALUMINUM PROPELLER 9.30X10 RIGHT

Function and technical context

The 9.30×10 aluminum propeller is the fundamental propulsion element that transforms the power of the engine into movement of the boat through the water. Mounted directly on the engine output shaft, it works in the propulsion system, generating thrust by rotating its blades in the aquatic environment. Its diameter of 9.30 inches and pitch of 10 inches are calculated to optimize acceleration and cruising speed in engines from 9.9 to 20 hp. A worn or damaged propeller significantly reduces propulsion efficiency, increases fuel consumption and can cause excessive vibrations that affect the structure of the boat.

When to replace this part?

Aluminum propellers suffer progressive erosion due to cavitation, marine corrosion and impacts against submerged objects, manifesting as loss of power, abnormal noise during navigation, engine vibrations or difficulty reaching maximum revolutions. It is recommended to visually inspect the propeller at least every sailing season and replace it when there are cracks, deformations in the blades or visible misalignment. Preventively changing a worn propeller avoids overloading the engine and costly repairs to the drive shaft during navigation.
