MULTI-E PROPELLER ALUM.AMITA4 14X21 RIGHT

Function and technical context

The Multi-e ALUM.AMITA4 14X21 right-hand rotation propeller is the propulsion element that transforms the engine power into direct thrust. Mounted on the tail shaft, it works in the marine transmission system, propelling the boat through the accelerated expulsion of water. Its four-blade aluminum design optimizes hydrodynamic efficiency in medium-power engines. A failure or wear on the propeller causes reduced speed, abnormal vibrations, excessive fuel consumption and possible cavitation that damages the drive shaft.

When to replace this part?

Inspect the propeller at least every boating season, especially after groundings or impacts with submerged objects. Cracks, deformations in the blades, surface erosion or excessive play in the shaft are clear indicators of immediate replacement. Annual preventive inspection and replacement at the first signs of damage prevents unforeseen breakdowns in navigation and prolongs the life of the drive shaft and gearbox.
