Yamaha Fuel Filter QB1-M10EL-10-00

Supersession Notice: QB1-M10EL-10-00 supersedes MAR-M10EL-00-00 and MAR-MINIF-IL-TR.

The Yamaha QB1-M10EL-10-00 is the compact “Mini” fuel/water separating filter used on many smaller Yamaha outboards. It is designed for engines that do not require the higher flow rate of a full-size separator, while still delivering the filtration Yamaha recommends for clean, dependable fuel supply.

This filter separates water and filters fuel down to 10 microns before it reaches critical fuel system components. That level of filtration is especially valuable with ethanol-blended fuels, which can absorb moisture and loosen debris inside fuel tanks and fuel lines over time. By stopping contaminants early, the Mini filter helps support smooth running, easier starts, and long-term reliability.

You will typically see the QB1-M10EL-10-00 specified for Yamaha outboards rated at 115 horsepower and below. Its compact footprint is ideal for tight rigging spaces while still providing strong protection against water and fine particulate contamination.
