Performance & Practical Benefits

A decal might not seem like much at first glance, but on an outboard that sees tough marine conditions, quality matters. The 8M0142570 decal stays tight and smooth against the cowling, even after long days under the sun or in rough saltwater environments. It will not curl at the corners, fade into a ghost of its former print, or slide off in humid weather.

Every time you lift the cowling, the clear reminder is right there—clean, crisp, impossible to miss. That little prompt can save you from headaches down the line, especially during busy seasons when you are bouncing from long runs offshore to short evening cruises. Mercury’s adhesive formula keeps the decal firmly in place, making the cowling look neat and intentional, just like it did when it rolled out of the factory.

Installation is refreshingly simple. Clean the surface, line it up, press it down, and you are set. You can feel the decal lock into place with a secure grip, settling in as if it had always been part of your engine’s layout.

Why Buy OEM

There are plenty of aftermarket decals out there, but few match the durability and precision of an OEM product. Mercury’s decals are cut to the exact dimensions, use the correct typeface and layout, and are designed for the temperature swings and vibration cycles an outboard experiences. Aftermarket versions often fade early, wrinkle at the edges, or simply do not look right. With OEM, you get fit, longevity, and peace of mind. If you want your engine to look and function the way Mercury intended, this is the right choice.
