It's generally recommended to replace the fuel filter cartridge insert every 100 hours of operation or annually (whichever comes first) in the Mercury Racing SST-200, 200XS, 300XS Optimax and other Direct Fuel Injected (DFI) 2-stroke and Verado 4-stroke Mercury Marine Outboards.
 
The Buckshot Racing #77 Fuel Filter Tool, designed to replace Mercury Marine / Quicksilver 91-896661, is used to remove and install fuel filters on Mercury outboard engines.
 
This specialized tool makes the process easier and safer, especially when dealing with tightly sealed or hard-to-reach filters. How the Fuel Filter Tool Works?
 
Insert: The tool is designed to securely fit in the fuel filter or filter housing for a socket-style fit to grip the filter.
 
Remove: Once securely attached, the tool provides leverage to turn and loosen the fuel filter. This is particularly helpful for filters that are difficult to remove by hand due to tightness or limited access. The tool helps avoid damaging the filter or housing by providing a firm grip and even pressure.
 
Install: After the old filter is removed, the new filter is screwed into place. The tool can also assist in tightening the new filter, ensuring a proper seal without over-tightening, which could damage the filter or housing.
 
Safety and Precision: Using the correct tool minimizes the risk of fuel spills or accidents, ensuring a clean and precise operation. It also prevents damage to the filter, housing, or surrounding components that could occur if improper tools are used.
