STAINLESS STEEL PROPELLER RUBEX NS3-D 13X19 LEFT

Function and technical context

The INOX Rubex NS3-D 13X19 left propeller is the propulsion element responsible for transforming the rotary energy of the engine into forward movement of the boat. It works in the propulsion system, coupled directly to the output shaft of the marine engine, where it experiences continuous hydraulic and mechanical loads. Its 13-inch diameter and 19-inch pitch are calibrated to optimize the engine's power curve, guaranteeing efficiency in cruising and controlled acceleration. Rubex stainless material provides superior resistance to marine corrosion, salt pitting and wear caused by cavitation, significantly extending its useful life compared to conventional alloys. A worn, deformed or damaged propeller causes loss of thrust, excessive vibrations, increased fuel consumption and possible damage to the shaft and bearings.

When to replace this part?

Check the condition of the propeller when you notice reduced revolutions under load, abnormal engine vibrations or erratic behavior of the boat while sailing. If you detect blades with dents, cracks, visible corrosion or uneven edge wear, it is time to replace them to regain propulsion efficiency. It is recommended to inspect the propeller before each sailing season and after prolonged navigation in waters with algae, debris or floating bodies that could damage it. Preventively replacing a damaged propeller prevents cascading damage to the propulsion system and ensures safe and predictable handling of the vessel, especially in emergency maneuvers.
