MULTI-E PROPELLER ALUM.AMITA3 14.50X19 LEFT

Function and technical context

The Multi-e ALUM.AMITA3 14.50X19 propeller is the propeller responsible for transforming the engine's power into effective traction, working directly in the marine propulsion system. Its left-hand rotation configuration is intended for specific installations where this rotation is required to balance dual-engine systems or comply with shipyard technical specifications. The aluminum material provides resistance to marine corrosion while maintaining an optimal operating weight, while its 14.50" diameter and 19" pitch dimensions guarantee the performance expected in medium displacement engines. Propeller failure—whether due to deformation, cavitation, or blade breakage—causes significant loss of thrust, excessive shaftline vibration, and possible secondary damage to the stern bearing and gearbox.

When to replace this part?

Check the propeller if you notice abnormal vibrations in the steering wheel, loss of maximum speed without changes in engine speed, or if you detect small cracks, pits or deformations in the blades after visual inspection. Aluminum propellers require seasonal inspection and preventive replacement when they show signs of advanced erosion or after impacts with submerged objects, as operation with a damaged propeller degrades fuel efficiency and accelerates drivetrain wear. Replacing the propeller preventively avoids unexpected groundings and costly repairs to the transmission system on demanding voyages.
