ALUMINUM PROPELLER 14.5X19 LEFT

Function and technical context

The left 14.5x19 aluminum propeller is the fundamental propulsion element that transforms the engine power into forward movement of the boat. Mounted directly on the drive shaft, it works in the marine propulsion system, where its specific design and pitch guarantee the efficient transfer of energy from the engine to the water. The progressive wear of the blades, cavitation or impacts against submerged objects compromise this power transmission, resulting in loss of speed, increased fuel consumption and greater effort on the engine to maintain the rpm regime.

When to replace this part?

Aluminum propellers require periodic visual inspection to detect deformations in the blades, radial cracks from the mating zone, accelerated erosion due to cavitation or loss of material due to galvanic corrosion. It is recommended to check the propeller at least once per sailing season, especially after anchoring in rocky areas or sailing in waters with submerged objects. The preventive replacement of a worn propeller avoids the risk of complete breakdown in navigation and significantly improves propulsive efficiency and engine consumption.
