STAINLESS STEEL PROPELLER RUBEX NS3-D 13.5X15 RIGHT

Function and technical context

The INOX Rubex NS3-D 13.5×15 propeller is the direct propulsion element that transforms the energy of the marine engine into forward movement of the boat. Coupled to the transmission shaft, it works in the propulsion system by converting the engine revolutions into hydrodynamic thrust through its stainless steel blades. Its three-bladed design provides a balanced distribution of forces, improving directional stability and reducing transmission vibrations. Stainless steel construction ensures resistance to marine corrosion, preserving structural integrity in saline environments and significantly extending its operational life.

When to replace this part?

The propeller requires periodic visual inspection to detect deformations, cracks, leading edge erosion or localized corrosion that reduce its hydrodynamic efficiency. Typical symptoms of deterioration include abnormal shaft vibration, progressive loss of revolutions at maximum power, or damage from impact against submerged objects. It is recommended to check the propeller at least once per navigation season and replace it preventively if it shows visible wear on the blades or if it has suffered impacts that alter its geometry, avoiding costly breakdowns in transmission systems during navigation.
