Lexor 14.8X23 Left Hand Propeller

Function and technical context

In a twin-engine installation, the counter-clockwise rotation of this propeller counteracts the reaction torque generated by the starboard engine, ensuring that the vessel maintains its heading without continuous rudder corrections. With a diameter of 14.8 inches and a pitch of 23 inches, the relationship between advance per revolution and rotational speed is optimized for medium-length vessels that demand a balance between cruising speed and load capacity. Acting as the final link in the hydraulic transmission, any imbalance in the blades is transmitted directly to vibrations in the propeller shaft and, from there, to the seals, bearings and gears of the reduction gearbox, accelerating their wear and compromising the integrity of the entire propulsion line.

When to replace this component?

The clearest signs that the propeller needs replacement are anomalous vibrations perceptible in the hull or at the wheel, persistent cavitation at cruising speed—which manifests as sudden loss of thrust and characteristic noise—the inability to reach design maximum RPM and lateral drift that is unrelated to wind or current. It is recommended to visually inspect the blades at each haul-out or at least once per season, checking for the absence of nicks, deformations or cavitation erosion on the leading and trailing edges. Replacing the propeller at the first structural symptom avoids progressive damage to the gearbox and shaft seals, whose repair is considerably more expensive than preventive replacement of the propeller itself.
