MULTI-E PROPELLER ALUM.AMITA3 14.30X21 RIGHT

Function and technical context

The propeller is the fundamental propulsion element of the marine transmission system, responsible for converting engine power into thrust and movement of the hull. This four-blade aluminum propeller works directly coupled to the engine output shaft, transmitting the rotation generated by the inversion and reduction gear system. Poor propeller operation directly affects the running efficiency, fuel consumption and acceleration capacity of the boat. The specific pitch and diameter design ensures the optimal operating curve in the manufacturer's recommended revolution range.

When to replace this part?

It is advisable to check and evaluate the condition of the propeller when detecting loss of traction, abnormal vibrations during navigation, or changes in driving behavior despite the engine working correctly. Aluminum degrades due to cavitational erosion, impact with submerged objects and galvanic corrosion in salt water, so it is advisable to inspect the propeller at least once a season and replace it if it has deep dents, cracks or deformations that affect the aerodynamics of the blades. A preventive replacement prevents breakdown at sea and guarantees maximum propulsion efficiency.
