LEXOR MULTI-E PROPELLER 15.8x15 LEFT

Function and technical context

The propeller is the component responsible for transforming engine power into propulsive thrust through rotation in the water. In Yamaha stern engines, the propeller works directly coupled to the transmission shaft, generating the movement necessary to move the boat. Its left-hand turn design is specifically calibrated for these models, ensuring correct interaction with the transmission system and hydrodynamic efficiency. Progressive wear of the blades reduces the available thrust, increases fuel consumption and can cause excessive vibration in the boat structure.

When to replace this part?

The propeller should be inspected after each boating season or every 100-150 hours of operation, especially if operating in water with vegetation, rocks or sand. Symptoms of wear include loss of maximum speed, abnormal increase in revolutions without speed gain, vibration in the tiller and increased fuel consumption at constant speed. Dents, cracks in the blades or erosion of the leading edge compromise hydrodynamic lift: preventive replacement prevents sudden breakage during navigation and optimizes engine performance.
