STAINLESS STEEL PROPELLER RUBEX NS3-D 13.3X17 RIGHT

Function and technical context

The Rubex NS3-D 13.3x17 INOX propeller is the fundamental propulsion element that transforms the mechanical energy of the marine engine into movement of the vessel. This three-blade propeller works in the transmission system, coupled to the boat's shaft through the reduction box. Its high-resistance stainless steel design guarantees durability in saline and freshwater environments, withstanding the traction and torsion forces generated during navigation. Propeller failure or wear drastically reduces propulsive efficiency, increases fuel consumption and can cause abnormal vibrations that damage the shaft and bearings.

When to replace this part?

The propeller requires visual inspection at each seasonal inspection to detect deformations, cracks, erosion of the leading edges or loss of material on the blades. It is common to observe damage due to cavitation, impacts against submerged objects or galvanic corrosion that compromise the aerodynamic profile. Replacing the propeller preventively when any of these symptoms occurs prevents it from continuing to generate dynamic imbalance, reduces stress on the engine and maintains navigation performance in optimal conditions.
