Overview

Anyone who’s spent enough time around a boat knows the feeling—you’re ready to get out on the water, but a stubborn fuel connection threatens to slow the entire day down. That’s exactly why the Mercury 8M0146934 Fuel Quick Connect is such a small but indispensable piece of gear. It clicks in with that confident, “you’re good to go” sound, giving you the peace of mind that your fuel line is locked, sealed, and ready for the next run.

Performance & Practical Benefits

A reliable fuel connection might not be the flashiest part of your engine setup, but it directly affects how confidently you run your boat. This quick connect locks into place with a tight, positive feel that leaves no doubt the fuel line is secure. When you’re bouncing over chop or trimming up to get on plane, you want that connection to stay steady—and this one does. It’s built to handle heat, vibration, and the chemical demands of modern ethanol-blended fuels without softening, swelling, or cracking.

Because it’s an exact OEM match, installation is simple and intuitive. No wiggling, forcing, or second-guessing. It aligns cleanly with the factory fitting, seats firmly, and helps ensure smooth, uninterrupted fuel flow. In real-world use, that translates to better throttle response, fewer hiccups, and less time spent tracking down avoidable issues.

Why Buy OEM

When it comes to fuel delivery, cutting corners never pays off. Mercury’s OEM parts are designed and tested specifically for Mercury engines—not generics, not “one-size-fits-most.” With the 8M0146934 connector, you’re getting a part that’s engineered to fit right the first time, hold up in harsh marine environments, and give you the reliability Mercury owners depend on. Aftermarket options may look similar, but they rarely match the durability, sealing quality, and precision that Mercury builds into every component.

If you’d rather be boating than troubleshooting, OEM is the way to go.
