ALUMINUM PROPELLER 15X15 LEFT

Function and technical context

The left 15x15 aluminum propeller is the fundamental propulsion element that transforms the power of the engine into movement of the boat. Coupled directly to the drive shaft, it works in the marine propulsion system, generating traction through rotation in the water. Its specific design with 15-inch pitch and 15-inch diameter is optimized for medium to high-power engines, ensuring maximum efficiency in converting revolutions to speed and displacement. Aluminum provides resistance to marine corrosion, prolonged durability and facilitates disassembly in case of breakdown, being a standard material in recreational and professional propulsion.

When to replace this part?

The propeller requires periodic visual inspection looking for cracks, deformations in the blades, loss of metal due to corrosion or cavitation, and rubbing against the hull or shaft. Symptoms of wear include abnormal vibrations during navigation, reduction in maximum speed without changes in engine speed, loss of traction during maneuvers or metallic sounds coming from the stern area. It is recommended to check the condition of the propeller before each intensive navigation season and after any impact or passage through very shallow waters; Preventive replacement prevents blade detachment in navigation, propeller accidents and costly drive shaft breakdowns.
