MERCURY GASOLINE FILTER 35-877565T REC35-877565T

Function and technical context

This petrol filter plays a critical role in the fuel supply system of Mercury 4-stroke engines, filtering impurities, particles and sediments present in the fuel before it reaches the carburetor. A dirty or deteriorated filter allows the passage of contaminants that clog the injectors and fuel passages, causing misfires, progressive loss of power and poor starts. Regular replacement ensures a clean and constant fuel flow, essential to maintain engine efficiency and prolong the life of the fuel system.

When to replace this part?

Petrol filters should be inspected at each seasonal maintenance and replaced when they become dark, visible deposits, or when a reduction in engine performance is observed. It is recommended to change the filter preventively every 100-150 hours of operation or annually, whichever comes first, especially if the fuel used comes from old tanks or unreliable gas station pumps. A preventive replacement avoids unexpected breakdowns in navigation and significantly prolongs the durability of the carburetor and injection systems.
