STAINLESS STEEL PROPELLER RUBEX NS3-D 13.8X13 RIGHT

Function and technical context

The right INOX Rubex NS3-D 13.8×13 propeller is the propulsion element responsible for transforming the engine power into directional thrust of the boat. It works in the propulsion system, coupled to the output shaft of the marine engine, and its stainless steel geometry guarantees maximum hydrodynamic efficiency even in aggressive saline environments. The specific diameter and pitch of this configuration directly determine the maximum speed, starting torque and fuel consumption of the propeller. Advanced wear, cavitation or deformation of the blade reduces the available thrust, increases the vibrations transmitted to the hull and compromises the maneuverability of the ship.

When to replace this part?

Symptoms of propeller wear include abnormal engine vibrations, progressive loss of maximum speed, increased fuel consumption without apparent cause and cavitation noise during acceleration. It is recommended to visually inspect the propeller at least once per boating season, especially after boating in debris water or rocky areas. Preventively replacing a worn propeller avoids secondary damage to the drive shaft and tail bearing, repairs that are significantly more expensive than replacing the propeller.
