PIER 24-825453

Function and technical context

The 24-825453 spring is a fundamental suspension component in the mechanical structure of low displacement Mercruiser outboard motors and propellers. This part provides the tension and elastic recovery necessary to maintain the alignment of internal components subjected to continuous vibrations during the operation of the marine engine. Working within the anchoring and support system of the engine block, the spring absorbs the load fluctuations and vibrations typical of combustion, preventing these forces from being transmitted in an uncontrolled manner to the fixing supports and the structure of the boat. Its correct function is essential to ensure operational stability and extend the useful life of adjacent components.

When to replace this part?

Suspension springs tend to lose their elastic capacity after prolonged compression and expansion cycles, which manifests itself in abnormal vibrations, metallic noises at idle or during acceleration, and visible misalignment of the powertrain. It is recommended to inspect this component at each navigation season inspection, especially after intensive navigation or in rough sea conditions. Preventative replacement of this spring prevents chain damage to brackets and flanges, costly repairs that could be detected too late at sea.
