Designed for Mercury’s advanced 2-stroke engines, this Quicksilver inline fuel filter fits a broad range of direct-injected outboards (Optimax and similar models from 65HP all the way to 300HP). If you own an Optimax (e.g. 75-150HP), a Pro XS (115-250HP) or even a high-performance Mercury Racing DFI engine, this filter is the correct choice for under-cowl fuel filtration. It sits in the fuel line feeding the injectors and plays a critical role in removing fine debris and emulsified water from the gasoline before it reaches the sensitive fuel injection components. Over time, even small contaminants can affect the performance of DFI engines, causing rough running or reduced power – this filter prevents those issues from occurring.

By replacing this filter at the recommended intervals, you keep your engine running like new. Mercury suggests periodically checking and changing the under-cowl inline filter (at least once per year or every ~100 hours) because direct injection systems are very demanding on fuel cleanliness. Installation is straightforward: simply disconnect the fuel line, remove the old filter, and install the new one, noting the arrow on the filter that indicates fuel flow direction. Keeping a clean filter in place ensures your Optimax/DFI motor will start easily, run smoothly, and deliver full power when you need it.

Ideal for high-performance bass boats, sport boats, or workboats powered by Mercury Optimax/DFI outboards where flawless fuel delivery is critical for maximum power and acceleration
Suitable for models such as Optimax (75-150HP, 3-cyl and V6), Pro XS (115, 150, 175, 200, 225, 250HP) and Mercury Racing/SportJet DFI – this filter ensures each cylinder gets clean fuel even under extreme demand
Preventative maintenance: Regular replacement (at least annually) protects expensive fuel system components (like the compressor and injectors) from damage caused by dirty fuel
Guaranteed quality: As a genuine Quicksilver part, this filter provides an exact fit and reliable service, maintaining Mercury’s specifications and any applicable engine warranty
