RUBBER 25-855690
Description
Function and technical context
Rubber 25-855690 is a damping and sealing component that is an integral part of Mercury, Mariner and Mercruiser propulsion systems. This piece fulfills a double critical function: it acts as a sealing gasket to prevent leaks of cooling and lubrication fluids, and simultaneously it functions as a vibration isolator that absorbs the vibrations generated by the engine, reducing them before they are transmitted to the hull of the boat. Its correct operation is essential to maintain the integrity of the refrigeration circuit and preserve the useful life of the bearings and mechanical organs that depend on vibration isolation.
When to replace this part?
The sealing and damping rubbers degrade over time, exposure to engine heat and the action of salt water, manifesting symptoms such as visible coolant or oil leaks, increased vibrations transmitted to the hull, or visible deterioration of the elastomer. It is recommended that this rubber be inspected at each seasonal maintenance and replaced if it shows cracks, hardening, advanced discoloration or loss of elasticity. Preventive replacement of this part prevents costly secondary damage to the cooling system and structural instability problems that may appear during navigation.
