MULTI-E PROPELLER ALUM.AMITA3 14.20X23 RIGHT

Function and technical context

The Multi-e ALUM.AMITA3 14.20X23 Right propeller is the direct propeller of Yamaha outboard motors, responsible for transforming the engine's power into hydraulic thrust to move the boat. Mounted on the transmission shaft, it works in the aquatic propulsion system, where its four-blade aluminum design optimizes traction and maneuverability. A worn or damaged propeller significantly reduces maximum speed, increases fuel consumption and can cause abnormal vibrations that affect the structure of the stern.

When to replace this part?

Aluminum propellers suffer progressive wear due to cavitation, impacts with submerged objects and marine corrosion. The most obvious symptoms are loss of maximum speed, vibrations in the tiller, abnormal petrol consumption or difficulty in reaching the nominal engine revolutions. It is recommended to check the condition of the propeller at the beginning of each navigation season and replace it preventively if it presents deformations, cracks or visible erosion on the leading edges of the blades; This intervention prevents unforeseen breakdowns in open water and maintains engine performance in optimal conditions.
