Sierra 18-79910 Fuel Filter Assembly, Replaces Yamaha 61N-24560-10, Fits 9.9-90HP Outboards

The Sierra 18-79910 Fuel Filter Assembly is a direct replacement fuel filter built for Yamaha outboard engines, designed to trap contaminants and moisture before they reach the carburetor or fuel injection system. Keeping fuel clean protects internal engine components from the debris, varnish, and water that commonly accumulate in marine fuel systems, and a clogged or failed filter assembly is a frequent cause of hard starting, stalling, and rough running in Yamaha outboards. This assembly is constructed with a metal outer housing for durability in the marine engine bay and installs in place of the original Yamaha filter assembly using the factory mounting configuration.

The 18-79910 is engineered to meet or exceed the specifications of the original equipment part it replaces, and it directly interchanges with several Yamaha factory part numbers, so boat owners can confirm compatibility by checking the numbers stamped on their original filter assembly against the cross-reference list below. It is intended as a routine maintenance and repair item for Yamaha outboards ranging from small portable engines up through mid-range four-stroke and two-stroke models, covering both HP-designated and lettered Yamaha model lines.
