RUBEX 3-E ALUMINUM PROPELLER 14.8X17 RIGHT

Function and technical context

The RUBEX 3-E 14.8×17 aluminum propeller is the propeller responsible for transforming the power of the marine engine into displacement movement of the boat. This piece works directly in the propulsion system, where it transmits the rotation of the tail shaft towards the water, generating the thrust necessary for advancement and maneuvering. Its three-bladed geometry has been developed through hydrodynamic engineering to minimize vibrations and ensure balanced operation at different speeds and loads. The right-hand rotation configuration is essential for compatibility with specific propulsion systems, and the aluminum construction provides superior resistance to marine corrosion, critical in saline environments where wear accelerates structural deterioration.

When to replace this part?

Common symptoms of propeller wear include abnormal vibrations transmitted to the hull during navigation, progressive loss of top speed without changes in engine revolutions, visible cracking or erosion on the blades, and metallic noises coming from the propulsion area. Although the replacement interval depends on the intensity of use and navigation conditions, it is recommended to inspect the condition of the propeller at each seasonal inspection and consider its preventive replacement every 3-5 years of active navigation or when the aforementioned symptoms are detected. Replacing the propeller preventively avoids imbalances that can damage the tail shaft and other critical structures, in addition to preventing possible maneuverability problems in emergency situations.
