ALUMINUM PROPELLER 14.50X19 RIGHT 48-832830A45

Function and technical context

The 14.50x19-inch aluminum propeller is the direct propulsion element that transforms engine power into hull movement through the water. Mounted on the tail shaft, it works in the marine transmission system, propelling the boat through the controlled rotation of its 15 splines in a right-hand rotation configuration. This part is critical for hydrodynamic efficiency: a worn, bent or eroded propeller significantly reduces maximum speed, increases fuel consumption and can cause abnormal vibrations that are transmitted to the entire aft structure, with the risk of damage to the drive shaft and support bearings.

When to replace this part?

Symptoms of propeller wear include progressive loss of cruising speed, abnormal increase in revolutions without speed gain, audible cavitation (bubbling noise during acceleration), or visible damage such as nicks, cracks or deformations in the blades. It is recommended to inspect the propeller at least once a year during seasonal maintenance, especially after sailing in shallow water, rocky areas or after hitting submerged objects. Preventive replacement prevents sudden failures in the middle of the sea and protects the integrity of the drive shaft, which is significantly more expensive to repair.
