ALUMINUM PROPELLER 14.2X23 LEFT

Function and technical context

The left 14.2x23 aluminum propeller is the fundamental propulsion element that transforms the power of the Mercury engine into movement of the boat. Working in the marine drive system, this propeller generates traction by moving water rearward, allowing the hull to move forward with hydrodynamic efficiency. Its size and pitch are calculated to optimize performance in engines from 135 to 300 hp, guaranteeing controlled acceleration and stable cruising speed. Progressive wear of its blades or deformation due to impact reduces thrust capacity, causing loss of speed, excessive fuel consumption and annoying vibrations that are transmitted to the entire hull structure.

When to replace this part?

Aluminum propellers show wear when unusual vibrations appear at certain revolutions, progressive loss of thrust or the presence of visible nicks and scratches on the blades after contact with submerged objects. It is recommended to inspect the propeller at the beginning of each sailing season and after any impact with floating objects, removing preventively if deformations or cavitation are detected. Replacing the propeller on time prevents premature wear of the tailshaft and drive bearings, which results in much more expensive repairs and downtime for the boat.
