ALUMINUM PROPELLER 14.8X15 RIGHT 48-78116A45

Function and technical context

The 14.8×15 aluminum propeller is the fundamental propulsion element that transforms the engine power into movement and direction of the boat. Coupled directly to the engine drive shaft, this propeller generates traction through the controlled rotation of its blades in the water, allowing acceleration, braking and maneuvering with precision. Its right-hand turning design makes it compatible with standard configurations of medium-high power Mercury and Honda outboard motors. Progressive wear, fracture or loss of efficiency in the blades significantly reduces maximum speed, increases fuel consumption and can compromise maneuverability and navigation safety.

When to replace this part?

Aluminum propellers show visible wear in the form of erosion on the edges of the blades, small deformations or loss of metallic luster after thousands of hours of operation and exposure to salt water. Common symptoms include abnormal vibration during navigation, loss of acceleration without changes in engine speed, or inability to reach maximum revolutions. It is recommended to inspect the propeller at each seasonal maintenance and replace it preventively if cracks, deformations or significant erosion are detected; This investment avoids sudden breakdown in navigation and additional deterioration of the transmission shaft and gears.
