MULTI-E PROPELLER ALUM.AMITA3 14.50X19 RIGHT

Function and technical context

The Multi-e ALUM.AMITA3 14.50X19 propeller is the essential propulsion component that transforms the rotary power of the marine engine into direct traction through the action of its blades on the water. Installed on the output shaft of the engine, this propeller mechanically transfers all the available power of the propeller, determining the displacement efficiency and fuel consumption of the vessel. Its alloy aluminum construction provides inherent corrosion resistance in saline environments, while the Multi-e design optimizes hydrodynamic performance over a wide range of operating regimes. The progressive deterioration of the blades, whether due to fatigue, cavitation or impacts, directly reduces the available traction, causes excessive vibrations in the drive shaft and increases fuel consumption considerably.

When to replace this part?

The most obvious symptoms of wear include abnormal shaft vibrations during navigation, a noticeable reduction in revolutions even at maximum acceleration, metallic noises coming from the propulsion area and the appearance of visible cavitation around the blades. It is recommended to thoroughly inspect the propeller at the beginning of each sailing season and immediately after any contact with a submerged object, since although no superficial damage is visible, there may be internal microcracks that seriously compromise performance. Preventive replacement after detecting these signs avoids catastrophic failures in navigation and significantly prolongs the useful life of the entire propulsion system.
