Quicksilver 2-Micron Fuel Filter Element 35-8M0122423 for Mercury Outboards (75–400HP) & MerCruiser 4.5L/6.2L

This Quicksilver fuel filter element provides state-of-the-art filtration for a wide range of Mercury engines – from mid-size 75HP outboards up to flagship 350–400HP Verado models – as well as late-model MerCruiser MPI (multi-point injection) inboards. With a filtration rating of 2 microns, it is designed to remove even the tiniest contaminants and emulsified water from gasoline, which is crucial for today’s high-pressure fuel systems. It supersedes older part numbers (such as 8M0060041) and is used in under-cowl filter assemblies or Vapor Separator Tank (VST) modules depending on the engine model.

Whether you have a 115HP Pro XS outboard, a supercharged 350HP Verado, or a MerCruiser 4.5L sterndrive, this filter element will ensure your fuel stays ultra-clean. Installation is simple: on outboards, unscrew the filter cap under the cowling and swap the element; on MerCruiser engines, open the fuel filter housing. It’s recommended to change this fine filter element at least every 100 hours or once a season, because even small amounts of debris can reduce engine efficiency or cause fuel starvation at wide-open throttle.

• Ideal for modern Mercury FourStroke and Verado engines where high-precision filtration protects expensive fuel rails and injectors – e.g., during watersports or offshore fishing when reliability is paramount
• Also crucial for Optimax/Pro XS 2-stroke engines that require clean fuel for the compressor and injection system to function properly – this filter eliminates particles that could upset these high-performance machines
• Tip: Check and replace this 2-micron filter regularly, especially if refueling at various marinas – it will safeguard your engine from unexpected hiccups at full throttle
• Choose OEM: Using a genuine Quicksilver filter is the best way to maintain your engine’s warranty and ensure it receives the protection the manufacturer intended
