ALUMINUM PROPELLER 14.3X21RIGHT 48-832832A45

Function and technical context

The 14.3x21 aluminum propeller is the fundamental propulsion element that transforms the mechanical power of the engine into direct thrust. It works in the marine propulsion system, coupled directly to the engine output shaft or the sterndrive system on outboard engines and Command Thrust systems. This part is critical because any imbalance, deformation or loss of material directly reduces navigation performance, affects the maximum achievable speed, increases fuel consumption and can cause vibrations that are harmful to the engine and the structure of the boat.

When to replace this part?

Aluminum propellers present characteristic symptoms of wear such as visible cavitation (small craters on the surface), deformations in the blades, dents due to impacts with submerged objects, and marine galvanic corrosion despite protective treatments. It is recommended to inspect the propeller at least once per nautical season and before each prolonged outing; Preventive replacement prevents unpredictable breakdowns at sea and ensures optimal operation of the engine with respect to its nominal revolutions. A damaged propeller not only reduces power, but forces the engine to work with greater stress, shortening its useful life.
