MULTI-E PROPELLER ALUM.AMITA3 14.80X17 RIGHT

Function and technical context

The Multi-e ALUM.AMITA3 14.80×17 propeller is the fundamental driving element of the marine propulsion system, transforming the power of the engine into forward movement of the boat. Installed on the tail shaft, it works within the marine transmission system, transferring the engine's rotation to the water through its blades designed to generate efficient traction. The 14.80-inch diameter and 17-inch pitch are optimized to balance acceleration and cruising speed, providing balanced performance in general boating. A defective, worn propeller or with damage to the blades causes loss of effective power, abnormal structural vibrations, a significant increase in fuel consumption and possible cavitation that compromises maneuverability and navigation safety.

When to replace this part?

Aluminum propellers show progressive wear due to salt water erosion, galvanic corrosion and blade abrasion; Characteristic symptoms include abnormal vibrations in the boat structure, loss of maximum engine revolutions, audible hum or cavitation, and visual inspection for cracks, dents, or erosion in the blades. It is recommended to check the condition of the propeller during each seasonal maintenance and replace it preventively if damage greater than 5-10% of the blade surface is observed, especially before long navigations or in high season. Proactive propeller changing prevents unexpected breakdowns at sea, ensures optimal propulsion performance throughout the season and prevents secondary damage to the drive shaft.
