Performance & Real-World Benefits

The 79023T10 fuse is simple but essential. It’s what stands between your electrical system and a fried wire harness. When an overload happens, this fuse sacrifices itself — cutting power before the damage spreads. It’s one of those inexpensive parts that can save you hundreds down the line.

Mercury builds it tough enough to handle the marine environment — constant vibration, salt air, and heat. If your old fuse looks corroded, discolored, or weak, swapping in a new one takes minutes and keeps your system safe.

Why Choose Mercury OEM

The Quicksilver 79023T10 isn’t just another fuse off the shelf. It’s the same part Mercury installs in new boats — tested for accuracy, quick response, and lasting durability. Cheaper fuses might not blow at the right amperage, which can leave your electrical system unprotected or, worse, cause false trips.

Mercury OEM parts are built to the highest marine standards, giving you confidence that your electrical protection is as solid as the rest of your setup.
