MULTI-D PROPELLER ALUM.AMITA4 13X15 RIGHT

Function and technical context

The 13 x 15-inch ALUM.AMITA4 multi-step propeller is the propulsion element that transforms the engine power into effective traction on the water. This aluminum component works in the transmission system, coupling directly to the engine output shaft to generate the necessary thrust. Its 13-inch diameter, 15-inch pitch geometry is designed to optimize performance in medium-sized boats with medium-power engines. Propeller wear or deterioration generates abnormal vibrations, reduced cruising speed and increased fuel consumption, significantly affecting the operational efficiency of the vessel.

When to replace this part?

A propeller requires inspection and replacement when it presents bending, cracks, deformations in the blades or progressive erosion of the leading edge, symptoms that manifest themselves as persistent vibrations, abnormal noises during navigation or loss of acceleration. It is recommended to inspect the condition of the propeller at least twice per sailing season, especially after hitting submerged objects or sailing in areas with abrasive sediments. Preventively replacing a damaged propeller prevents mechanical overloads on the engine and significantly reduces the risk of costly drive shaft failures.
