Sierra 18-7713 Inline Fuel Filter, Replaces 35-80365M, Fits Mercury/Mariner 9.9/15 HP 4-Stroke & Yamaha Outboards

The Sierra 18-7713 is an inline fuel filter engineered as a direct replacement for Mercury Marine part 35-80365M on select Mercury/Mariner and Yamaha 4-stroke outboard engines. It installs in the fuel line ahead of the carburetor or fuel system to trap contaminants and debris before they can reach internal engine components, helping protect against clogged jets, fuel system wear, and rough running caused by dirty fuel. The filter housing is built from plastic for corrosion resistance in the marine environment, and the unit is designed to be located under the cowl on the outboard engines it fits.

This filter is compatible with Mercury/Mariner 9.9 HP 4-Stroke (1995-98) and 15 HP 4-Stroke (1998 & Up) outboards, as well as a range of Yamaha 4-stroke outboards including the 6, 8, F4, F9.9, and FT 9.9 models across multiple production years. As a Sierra part, it is built to meet or exceed the original equipment part it replaces and is backed by Sierra's Customer Satisfaction Warranty covering defects in workmanship and materials.
