PIER 24-825052 PAF25-05050011

Function and technical context

The 24-825052 PAF25-05050011 spring is a suspension and damping component integrated into the engine fixing system to the mounting bed. This spring absorbs the vibrations and movements generated during the operation of the propeller, protecting both the engine structure and the adjacent mechanical systems from excessive stresses. Its correct operation guarantees the structural stability of the drive assembly in different navigation conditions and operating regimes, avoiding vibration transmissions that could compromise the integrity of joints, fuel pipes and electrical systems.

When to replace this part?

The spring should be inspected when abnormal vibrations are detected in the engine, metallic noises during acceleration or loss of rigidity in the propeller mounting. Although there is no fixed hourly interval for all models, it is advisable to check the visual condition of the dock during each seasonal maintenance, especially on boats subjected to navigation in rough waters or intensive use. A weakened or deformed spring will not properly dampen vibrations, accelerating the wear of adjacent components and compromising the safety of the marine installation.
