Quicksilver 8M0122423 Fuel Filter Element - OEM Replacement

In this review of the Quicksilver 8M0122423 fuel filter element, the bottom line is simple: this is a direct, reliable OEM replacement for Mercury outboards and compatible MerCruiser sterndrive engines that need clean, contaminant-free fuel. The reviewer found it best for boat owners who want a drop-in part built to original equipment specifications that removes fine particles and moisture before they reach the engine. Installation is straightforward for anyone with routine mechanical experience and the right tool, and the filter's two micron rating is the single biggest reason to buy if preserving performance and avoiding fuel-related problems matters.

Key Features

• Direct replacement: Replaces Mercury Marine 8M0122424 for a seamless fit and original-equipment compatibility to avoid modification or adaptation.
• Two micron filtration: Captures very small fuel-borne contaminants and moisture to protect injectors and maintain engine performance.
• Under-cowl or housing fit: Designed to install under the outboard engine cowl or in sterndrive fuel filter housings for a tidy, factory-like installation.
• Meets OEM specs: Produced to Mercury Marine original equipment manufacturer specifications to ensure consistent protection and longevity.
• Broad engine coverage: Fits a wide range of Mercury outboards and certain MerCruiser engines, simplifying parts stocking for common service jobs.

Who It's For

This fuel filter element is aimed at owners and technicians maintaining Mercury outboards from smaller 75-125hp units up through high-power Verado and Pro XS outboards, as well as MerCruiser 4.5L and 6.2L sterndrive engines (serial No. 2A456613 and newer). It suits boaters who prioritize factory-fit parts and those performing routine in-season service to avoid power loss or injector problems caused by contaminated fuel.

It is not intended for engines outside the listed fitment or for users who need a multi-stage or water-separating primary filter as their only filtration solution; those with unique aftermarket setups or who require additional water separation should consider a dedicated secondary filter or sediment bowl in addition to this element.
