Review on Quicksilver 879885Q In-line Fuel Filter: Premium Solution for Mercury and Mariner Outboards by Chris Hanson

Quicksilver 879885Q Inline Fuel Filter is the last fuel filter located after the high pressure pump as shown in the attached photo. This filter is hidden under the motor's high voltage coil in the lower right corner of the motor; It is difficult to access but needs to be replaced if you want your engine to run efficiently. For the proper operation of the injectors and the engine itself, it is extremely important to change this filter every 60-80 hours of operation. Using a genuine Mercury part is a must - your engine deserves the very best and we strongly recommend using the Quicksilver 879885Q in-line fuel filter.
