LEXOR MULTI-E PROPELLER 15.80x15 RIGHT

Function and technical context

The Multi-e Lexor 15.80×15 right-hand turning propeller is the fundamental propulsion element of the transmission system in high-displacement Yamaha engines. Inserted in the tail shaft and driven by the gearbox, it transforms the rotation of the engine into hydrodynamic traction, propelling the boat forward or backward depending on the speed of travel. The 15.80-inch diameter and 15-inch pitch are calculated to balance acceleration and top speed in sport and recreational boats. Its wear, erosion due to cavitation or breakage directly affects the maneuverability, fuel economy and hydrodynamic behavior of the ship.

When to replace this part?

Propellers require periodic visual inspection for dents, cracks, leading edge erosion or blade material loss, typical symptoms of impact with submerged objects, prolonged cavitation or vibration fatigue. It is recommended to inspect the condition of the propeller at the beginning of each sailing season and after any stranding or contact with reefs and debris. Replacing the propeller preventively when these damages are detected prevents excessive vibrations that affect the tail bearings, seals and transmission organs, reducing costly repairs in the future.
