ALUMINUM PROPELLER 11.1X14 RIGHT 48-816706A40

Function and technical context

The 11.1×14 aluminum propeller is the fundamental propulsion element that transforms the mechanical energy of the engine into movement of the boat through rotation in the water. It works integrated into the marine transmission system, connected to the tail shaft and completely submerged in the aquatic environment. Its effectiveness is critical to overall performance: a worn, bent or cavitated propeller generates significant loss of thrust, increases fuel consumption and places excessive stress on the crankshaft and engine bearings, which can lead to costly breakdowns if not replaced in time.

When to replace this part?

Common symptoms of wear include progressive loss of maximum speed, abnormal vibrations in the structure of the boat, reduced grip during acceleration, or visible deformation of the blades after impacts with submerged objects. It is recommended to inspect the propeller during each seasonal maintenance and replace it if it presents surface erosion, microcracks, fractured blades or deformations that affect the rotational balance. Preventive replacement before the main boating season prevents unexpected strandings and emergency repairs at sea.
