ALUMINUM PROPELLER 14.2X23 RIGHT 48-832834A45

Function and technical context

The cast aluminum propeller is the fundamental propulsion element that transforms the engine's power into direct thrust towards the boat. This 14.2-inch diameter, 23-inch pitch propeller works in the marine propulsion system, connected directly to the engine output shaft via the drive tail. Its right-hand turn guarantees the correct trajectory and maximum use of engine torque, being critical to achieving optimal acceleration, efficient cruising speed and precise maneuverability. Proper propeller operation ensures that all available engine power is translated into effective hull displacement without excessive cavitation or hydrodynamic losses.

When to replace this part?

Aluminum propellers progressively degrade due to marine erosion, cavitation and accidental hits against submerged objects, manifesting themselves with a notable loss of revolutions at full throttle, abnormal vibration in the hull, irregular turning behavior or excessive fuel consumption. It is recommended to check the condition of the propeller at the beginning of each sailing season and after any visible impact, replacing it preventively if it presents cracks, deformations in the blades or advanced corrosion. Replacing a damaged propeller preventively avoids secondary damage to the drive shaft and drive shaft seals, repairs that are significantly more expensive than the propulsion part.
