ALUMINUM PROPELLER 9.30X7 RIGHT

Function and technical context

The propeller is the final component of the propulsion system responsible for converting the engine's mechanical energy into boat motion. This 9.30x7-inch aluminum propeller works in conjunction with the drive shaft, transferring the engine's power to the water through its blades. The 7-inch pitch and 9.30-inch diameter are optimized for low and medium power engines, ensuring a balance between acceleration and cruising speed. Its aluminum construction provides resistance to marine corrosion and facilitates periodic maintenance, being especially critical for maintaining propulsion efficiency and avoiding excessive vibrations that could damage the drive shaft or tail bearings.

When to replace this part?

The aluminum propellers show wear due to erosion, cavitation or impact with submerged objects, manifesting with progressive loss of power, abnormal vibration of the engine in cruise or atypical noises in the transmission. It is recommended to inspect the propeller at the beginning of each sailing season and replace it if it shows visible deformations, cracks or loss of material on the blades. Preventive replacement is especially important before long voyages, as a damaged propeller not only reduces speed and increases fuel consumption, but can cause catastrophic failure of the drive system at sea.
