79-79889A1 – Cover Kit – Mercury

79889A1 cover kit offers a simple and effective solution to blank out unused instrument holes or to prepare your dash for future gauge upgrades. As an OEM-spec part from Mercury, this cover kit fits standard 2-1/8" (54 mm) gauge cutouts, allowing a clean finished look when you remove a gauge or want a blank panel.

The kit includes a sealed cover and all necessary hardware to secure it properly. You attach it just like a regular gauge — mounting flush into the dash cut-out to give a clean, factory-style appearance. Because it uses genuine Mercury parts and dimensions, it fits seamlessly in dashboards originally built for Mercury/Quicksilver instruments.

Use 79889A1 cover kit whenever you remove a gauge (for upgrade, repair or replacement) but want to keep the dash tidy and weather-resistant. It also helps prevent dust, water ingress, or debris from entering empty instrument holes.

For boat owners restoring older Mercury outboards, or re-rigging dashboards with different gauge layouts, this cover kit provides a low-cost, OEM-compatible way to maintain a neat, professional finish — without leaving unsightly open holes.
