Lexor Propeller 14.9X22 Right Hand

Function and Technical Context

The Lexor 14.9 × 22 inch right-hand propeller acts as the final propulsive element in the marine transmission line, converting the rotational torque of the engine into net thrust on the water. With a diameter of 14.9 inches and a pitch of 22 inches, this fixed-pitch propeller is designed for installations on medium to high-power outboard and inboard engines, where the balance between pulling capacity and cruising speed is critical to overall vessel performance. The right-hand rotation sense—clockwise viewed from the stern—makes it specific to standard single-engine configurations or to the starboard position in twin-engine installations; using an incorrect rotation sense generates uncompensated torque forces that severely compromise maneuverability. A damaged or incorrectly selected propeller causes cavitation, vibrations transmitted to the transom, continuous engine overstress, and premature degradation of the stern gland seal and tail shaft bearings.

When to Replace This Propeller?

The clearest symptoms indicating propeller replacement is needed are: anomalous vibrations perceptible at the stern even at cruising rpm, inability of the engine to reach the maximum RPM range recommended by the manufacturer, persistent cavitation manifested as sudden loss of thrust accompanied by suction noise, and visible blade damage—warping, cracks, nicks, or deformations—following impact with submerged objects. Visual inspection of the blades is recommended at each seasonal haul-out, and dynamic balance verification every 200–300 hours of operation, since any deformation, however slight, alters effective pitch and penalizes both performance and fuel consumption. Replacing the propeller preventively at the first symptom prevents progressive imbalance from compromising the tail shaft, stern gland seal, or bearings—failures considerably more expensive than the propeller itself.
