ALUMINUM PROPELLER 15.50X15 RIGHT 48-832828A45

Function and technical context

The aluminum propeller is the direct propeller responsible for converting engine power into thrust and movement of the boat. It works integrated into the propulsion system of Mercury outboard motors, transmitting the rotation of the tail shaft towards the water. Its 15" pitch design offers an optimal balance between initial acceleration and sustained cruising speed, adapting to recreational and professional boats. A worn, cracked or propeller with damaged blades significantly reduces engine efficiency, increases fuel consumption and causes abnormal vibrations that affect navigability and safety.

When to replace this part?

Replace the propeller when you detect a progressive loss of maximum speed, slow acceleration or vibrations during navigation, typical symptoms of aluminum wear or corrosion. Inspect the propeller annually at the beginning of the season, especially in salt water where corrosion is more aggressive; Preventive maintenance prevents sudden failures at sea and reduces repair costs. It is advisable to carry a spare propeller on board, as damage to the blades can occur without warning when sailing in waters with submerged obstacles.
