ALUMINUM PROPELLER 13.3X13 RIGHT 48-77340A45

Function and technical context

The right 13.3x13 aluminum propeller is the fundamental propulsion element that transforms the engine power into the displacement of the boat through rotation in water. This propeller works integrated into the propulsion system, coupled to the transmission shaft that receives energy from the engine. Its 15-groove design guarantees optimal water grip, ensuring efficient power transfer and precise maneuverability. The 13-inch pitch and 13.3-inch diameter are calibrated to maximize performance in engines from 40 to 140 hp, striking a balance between acceleration and top speed without compromising the durability or structural integrity of the drive shaft.

When to replace this part?

Aluminum propellers show visible wear when cavitations appear (bubbles and erosion on the blades), deformations or warping that cause abnormal vibrations during navigation, as well as progressive loss of thrust or abnormal fuel consumption. It is recommended to inspect the propeller at the beginning of each season and regularly check its condition after sailing in shallow, rocky waters or waters with the presence of algae and debris. Preventive replacement of a worn propeller prevents secondary damage to the drive shaft, bearings and couplings, repairs that are considerably more expensive than replacing the propeller.
