MERCURY OIL FILTER 35-822626Q15

Function and technical context

This oil filter is an essential component of the Mercury engine lubrication system, responsible for retaining impurities, metallic particles and contaminants that are generated during engine operation. Oil is constantly circulated through the filter, which traps abrasive deposits that would otherwise damage critical friction surfaces such as bearings, pistons and transmission gears. Its direct efficiency has an impact on the durability of the engine: a clogged or deficient filter allows harmful particles to reach vital lubrication areas, accelerating premature wear and reducing the useful life of the propeller.

When to replace this part?

Oil filters on outboard engines require periodic replacement during seasonal maintenance, generally every 100 hours of operation or annually, whichever comes first. Symptoms of aging include low oil pressure indicated on the instrument panel, dark or burnt-smelling oil when checking the level, and possible engine rubbing noises after starting. Performing the change preventively at each service avoids costly breakdowns at sea and ensures that the lubrication system works at optimal performance, especially in intensive navigation or contaminated water.
