RUBEX PROPELLER 11.1X13

Function and technical context

The Rubex 11.1×13 propeller is the direct propulsion element that transforms the power of the marine engine into movement of the boat through the water. Installed on the transmission shaft, it works in the propulsion system, where its blades generate thrust through the accelerated displacement of the fluid. Its 11.1-inch diameter and 13-inch pitch determine the speed and traction ratio of the motor; Wear, deformation or cavitation in the blades significantly reduces propulsive efficiency, increases fuel consumption and can cause vibrations in the structure.

When to replace this part?

The propeller requires periodic visual inspection at each grounding; Symptoms of need for replacement include blade deformation, visible cavitation, advanced corrosion, edge breakage or abnormal vibration when sailing at nominal speed. It is recommended to check the condition of the propeller at least once a year or after impacts against submerged objects, since progressive wear is not always evident but directly affects the performance and safety of the boat. A preventive replacement in season avoids unexpected breakdowns during navigation and ensures maximum propulsion performance.
