O-RING 93210-41042 REC93210-41042

Function and technical context

The 93210-41042 O-ring is a sealing gasket that is part of the sealing systems of critical components in outboard and marine engines. This part works in environments of variable pressure and direct contact with cooling or fuel fluids, guaranteeing the tightness of connections that, if failed, would allow liquid leaks or the entry of salt water into engine cavities. Its degradation or hardening compromises the integrity of the seal, causing fluid losses, accelerated internal corrosion and in extreme cases, water entry into vital propeller systems.

When to replace this part?

The O-rings lose elasticity after repeated compression-expansion cycles and exposure to temperature variations, manifesting with visible drips in the crankcase, progressive loss of coolant or symptoms of water entering the engine compartment. It is recommended to replace preventively every two years of intense use or during any major maintenance intervention where sealed components are disassembled; This replacement avoids larger repairs derived from internal corrosion or damage due to salt water infiltration in areas that are difficult to access.
