AMITA 3 ALUMINUM PROPELLER 7.8X7 RIGHT

Function and technical context

The AMITA 3-blade aluminum propeller is the fundamental driving element that transforms the rotation of the engine into movement of the boat. Coupled directly to the drive shaft, it converts the mechanical power of the engine into hydrodynamic thrust by displacing water. The 3-blade design optimizes efficiency in small and medium-tonnage recreational and professional boats, providing a balance between acceleration and cruising speed. Its durable aluminum construction ensures durability in salt and fresh water conditions, being critical to maintaining propulsion performance and avoiding excessive drag that would increase fuel consumption.

When to replace this part?

A propeller requires replacement when it shows visible deformations on the blades, scratches due to impacts against submerged objects, progressive erosion of the leading edge, or when abnormal vibration occurs during navigation at cruising speed. It is recommended to inspect the propeller at the beginning of each season and after any impact, as damage can affect dynamic balance and cause secondary damage to the shaft and bearings. Preventative replacement of a worn propeller is an investment that prevents costly repairs to the drive system and ensures stable performance of the boat.
