MULTI-E PROPELLER ALUM.AMITA3 14.80X17 LEFT

Function and technical context

The Multi-e ALUM.AMITA3 14.80X17 Left propeller is the propulsion element that transforms the power developed by the engine into forward thrust of the boat. It is coupled directly to the output shaft of the engine, receiving the rotation transmitted from the crankshaft through the gear system of the gearbox. The four-blade design distributes traction forces in a balanced way, optimizing hydrodynamic efficiency in different navigation regimes. A damaged propeller significantly reduces the available thrust, increases fuel consumption, generates unwanted vibrations throughout the structure and favors the appearance of cavitation that progressively erodes the blades until the structural integrity is compromised.

When to replace this part?

Change the propeller when you detect visible erosion on the blades caused by cavitation, deformations due to impact against submerged objects, cracks or breaks, or if the engine shows an inexplicable loss of power after checking the power and ignition systems. It is recommended to inspect the condition of the propeller at least once at the beginning of each boating season, especially if you operate in silty waters or areas with rocks and submerged obstacles. Preventive replacement before breakage prevents immobilization in water and secondary damage to the drive shaft.
