RUBEX 3-C ALUM PROPELLER 11.6X11 RIGHT

Function and technical context

The 3-blade Rubex aluminum propeller with a pitch of 11.6 inches and a diameter of 11 inches is the direct propulsion element that transforms the power of the engine into movement of the hull by rotating it in the right direction. This part works in the marine propulsion system, supporting the traction load and water resistance during navigation. Its performance is critical to the boat's fuel efficiency, maneuverability and top speed, as a damaged or misaligned propeller causes loss of thrust, shaft vibration and excessive fuel consumption.

When to replace this part?

The propeller requires replacement when it shows visible deformations in the blades, cracks in the leading edge, loss of material due to cavitation, or when the boat experiences abnormal vibrations, loss of useful revolutions or changes in turning behavior even with engines at nominal power. It is recommended to inspect the condition of the propeller every sailing season and check it especially after running aground, hitting submerged objects or prolonged navigation in waters with abrasive sediment. Preventively replacing a worn propeller avoids secondary breakdowns in the tail shaft, bearings and bow horn, as well as unwanted stops in navigation.
