STAINLESS STEEL PROPELLER RUBEX NS3-E 14.3X17 LEFT

Function and technical context

The INOX Rubex NS3-E 14.3×17 left propeller is the propeller responsible for transforming the rotational energy of the stern motor into hydrodynamic thrust to move the boat through the water. This part works directly coupled to the engine output shaft, in permanent contact with the salty marine environment, being responsible for the propulsive efficiency and general performance of the propulsion system. Its stainless aluminum construction resists the galvanic corrosion and oxidation that characterizes saltwater environments, ensuring that there is no material degradation or loss of performance due to electrochemical erosion. The sinister (left) direction of rotation is critical for correct mechanical compatibility with sterndrives configured in this rotation, ensuring effective traction and directional stability during navigation.

When to replace this part?

The propeller requires inspection and possible replacement when symptoms such as loss of maximum speed, abnormal vibrations in the structure of the boat, excessive cavitation (formation of bubbles), deformations in the blades, bumps or dents on the surface, or a notable increase in fuel consumption without an apparent cause in the engine are observed. It is recommended to inspect the propeller at the beginning of each sailing season and after any impact or navigation in waters with shallow draft or presence of submerged rocks and debris. Preventively replacing a damaged or worn propeller prevents overloading of the engine, damage to the drive shaft and costly repairs at sea that compromise the safety of navigation.
