MERCURY OIL FILTER 35-822626Q03

Function and technical context

The oil filter is an essential component of the lubrication system that retains dirt particles, combustion residues and metal debris from the engine oil. It works in the lubrication circuit, allowing only clean oil to reach bearings, pistons and cylinder walls, guaranteeing optimal protection against premature wear. Its periodic replacement is critical to maintain the viscosity of the lubricant and prevent the accumulation of contaminants that could compromise the integrity of the internal surfaces of the engine and significantly reduce its useful life.

When to replace this part?

It is recommended to change the oil filter every 100 hours of operation or at the beginning of each boating season, whichever comes first. Symptoms of a saturated filter include uneven oil pressure indicated on the gauge, clunking noises from the engine during acceleration, and a noticeable decrease in thrust power. Preventive replacement of the filter together with the oil change is the most economical practice to avoid costly repairs due to lack of adequate lubrication, especially in boats with intensive use or in marine environments with high salinity.
