PROPELLER LEXOR 14.5X25

Function and technical context

The Lexor 14.5×25 propeller is the propulsion element that transforms the mechanical power of the engine into direct thrust to move the boat. It works in the marine transmission system, coupled directly to the engine output shaft through the connecting bushing. Its variable pitch design and specific diameter are calculated to extract maximum efficiency from Yamaha engines in the medium-high power range, optimizing both acceleration and cruising speed. Significant wear on the blades or a curvature of the propeller shaft reduces propulsive efficiency, generating abnormal vibration, loss of maximum speed and inefficient fuel consumption.

When to replace this part?

Visually inspect the propeller at the beginning of each sailing season: symptoms such as deformations in the blades, knocks, cavitation (pitting on the surface), or rubbing against the shaft are unequivocal signs of necessary replacement. Marine propellers work in corrosive and high-friction environments; Annual review and preventive replacement is recommended every 2-3 intensive seasons of use or in the event of any impact with submerged obstacles. Replacing the propeller on time prevents harmful vibrations from being transmitted to the engine and transmission, preventing costly repairs and ensuring safe maneuverability while sailing.
