ALUMINUM PROPELLER 8.50X9 RIGHT

Function and technical context

The propeller is the fundamental propulsion element that transforms the engine's power into direct thrust on the water. This 8.50 x 9-inch aluminum propeller works coupled to the engine's transmission shaft, generating traction by rotating its blades in a right direction. The specific diameter and pitch are calibrated to optimize hydrodynamic efficiency in small and medium-sized boats, balancing acceleration and maximum speed. Progressive wear, cavitation or deformation in the blades significantly reduces the available thrust, causing loss of speed, increased fuel consumption and overloading of the transmission system.

When to replace this part?

The propeller requires visual inspection on each outing, especially after impacts against submerged objects, rocky bottoms or remains of nets that cause deformations, cracks or loss of material in the blades. Progressive erosive wear, cavitation in the form of pitting or abnormal vibrations during navigation are unequivocal signs that the propeller has lost efficiency and must be replaced. A preventive inspection is recommended before each sailing season and immediate replacement after any impact that affects the symmetry or integrity of the blades, thus avoiding secondary damage to the shaft and reducer that would result in considerably more expensive repairs.
