HELICR MULTI-E ALUM.AMITA3 15X15 LEFT

Function and technical context

The Helicr Multi-e ALUM.AMITA3 15X15 Left propeller is the propulsion element responsible for converting the power of the engine into translational movement of the boat. It works in the marine propulsion system, coupled to the engine output shaft, and interacts directly with the water to generate the necessary thrust. The aluminum design provides structural strength while maintaining controlled weight, while its 15x15 pitch configuration (diameter and pitch in inches) is calibrated to maximize hydrodynamic efficiency in medium-high displacement engines. Its left orientation (counter-rotating rotation) is critical for the directional stability and behavior of the vessel, especially in precision maneuvers and in twin-engine systems.

When to replace this part?

A propeller requires replacement when it presents visible cavitation (erosion or pitting on the blades), loss of material due to corrosion or impact, deformations that affect dynamic balance, or when abnormal vibration is detected in the drive shaft during navigation. It is recommended to inspect the propeller visually every season and after any impact with a floating object or bottom, since even small deformations reduce efficiency and overload the transmission system. Preventatively replacing a worn propeller prevents secondary damage to the tailshaft, bearings and clutch, reducing future repair costs.
