MULTI-E PROPELLER ALUM.AMITA4 14.80X15 LEFT

Function and technical context

The Multi-e ALUM.AMITA4 14.80X15 left propeller is the propulsion element that transforms the power of the engine into forward movement of the boat. Mounted directly on the tail shaft, it works in the propulsion system by transmitting the rotation of the engine to the water through its blades designed to generate hydrodynamic thrust. Its pitch and diameter configuration is calibrated for medium displacement engines, optimizing the relationship between speed and consumption. A failure in the propeller – deformation, cracks or misalignment – ​​causes excessive vibrations, loss of effective power and progressive damage to the motor shaft and bearings.

When to replace this part?

The propeller requires visual inspection each boating season: look for dents, radial cracks in the blades, or discoloration due to cavitation erosion. If you notice abnormal vibrations during acceleration, loss of maximum revolutions without gear changes, or the engine is working harder to maintain cruising speed, the impeller is likely damaged. It is advisable to check and replace preventively before each intensive season of use, especially if you navigate in areas with rocky substrates or submerged remains; A scheduled replacement avoids catastrophic breakdown at sea and long repair times in the dock.
