ALUMINUM PROPELLER 9.30X9 RIGHT

Function and technical context

The 9.30x9 aluminum propeller is the fundamental propulsion element that transforms the power of the engine into movement of the boat. Coupled directly to the engine output shaft, it generates the necessary thrust through the coordinated rotation of its blades in the water. The 9.30-inch diameter and 9-inch pitch design positions it as a versatile solution for medium-power engines, balancing acceleration and cruising speed. Its aluminum construction provides structural strength combined with lightness, allowing the engine to maintain an optimal rpm without mechanical overload. Poor operation or wear of the propeller directly affects engine performance, increasing fuel consumption and significantly reducing maximum navigation speed.

When to replace this part?

Aluminum propellers present visible signs of wear such as blade deformation, cavitation at the leading edges, accelerated surface corrosion or unusual vibrations during navigation. It is recommended to inspect the propeller each boating season and especially after boating in waters with minor obstacles or strandings, as aluminum is susceptible to impact damage. Preventive replacement of a damaged propeller prevents not only premature wear of the engine and shaft, but also unexpected power losses while sailing that can compromise the safety of the boat.
