ALUMINUM PROPELLER 14.8X17 RIGHT 48-832828A45

Function and technical context

The 14.8x17 aluminum propeller is the direct propulsion element that transforms the engine power into water thrust through rotation in the water. Coupled to the transmission shaft of the outboard or stern motor, it works in the marine propulsion system by converting the rotation speed of the engine into the displacement of the boat. Its 14.8-inch diameter and 17-inch pitch are optimized to provide a balance between fast acceleration and stable cruising speed in medium and high-power engines. Marine aluminum offers lightweight structural strength and excellent saltwater performance, preventing premature corrosion that would compromise boating performance and safety.

When to replace this part?

Symptoms of wear on a propeller include abnormal vibrations during navigation, progressive loss of speed or poor acceleration even with the engine at high revolutions, visible deformation of the blades or surface erosion due to cavitation and marine abrasion. It is recommended to check the condition of the propeller at least once per sailing season, especially after sailing in waters with debris or rocky bottoms, since cracks or partial breaks can cause imbalances that damage the drive shaft. Replacing the propeller preventively when the first signs of deterioration are detected avoids costly engine and transmission repairs, and ensures predictable and safe behavior of the boat in all navigation conditions.
