MULTI-D PROPELLER ALUM.AMITA3 13.50X15 RIGHT

Function and technical context

The propeller is the fundamental propulsion component that transforms the engine's power into direct thrust on the water. This 15-inch pitch, 13.50-inch diameter aluminum propeller runs in the drive system, coupled to the engine output shaft via the coupling cone. Its multidirectional design guarantees optimal performance in forward navigation with right turns, allowing a balanced distribution of forces during acceleration and cruising. Progressive wear of the blades or deformations in the aerodynamic profile causes loss of power, structural vibrations and a significant increase in fuel consumption.

When to replace this part?

Typical symptoms of deterioration include visible cavitation in the blades (surface erosion), progressive loss of acceleration even with the engine at maximum revolutions, abnormal vibration in the transmission system, and formation of cracks or fractures on the leading edge. It is recommended to visually inspect the propeller at least once per navigation season and, if damage due to corrosion, impact or erosion is detected, proceed with immediate replacement to avoid secondary damage to the tail shaft and tilt mechanism. A preventive replacement after 3-5 seasons of intensive use guarantees optimal performance and greater navigation safety.
