Mercury – Vented Splash Cover | Verado Series | White Polysoft II Fabric | 8M0228523

Overview

A white cowling looks incredible when it’s clean. It also shows everything—spray, water spots, sun haze, and the little scuffs that happen when you’re moving fast and living on the water. If you run a Verado, you already know the engine is built for work. This cover is about keeping the finish looking as solid as the performance feels.

What I like about a vented splash cover is the way it protects without slowing you down. You don’t have to baby the boat or change your routine. You slip it on, fire up, and head out. There’s a calm in that—knowing your gear is handled while you chase the day.

Performance & Practical Benefits

This is one of those parts that earns its value in the background. The cover slips on with a snug, intentional fit that feels secure, even when you’re running through chop and throwing spray behind the stern. It doesn’t feel loose or sloppy. It sits tight and steady, which is exactly what you want when the boat’s moving and the weather isn’t.

The Polysoft II fabric has a tough outer skin that stands up to wind, water, and bright sun. But the inside is gentler where it counts, helping reduce the kind of rubbing that can dull a finish over time. On a white engine, that matters. You’ll see fewer water spots baking in after a long run, and you’ll spend less time trying to scrub away the “film” that builds up from spray and sun.

What really makes it feel like a true running cover are the vents and access points. Side vents help keep airflow moving, while exhaust ports and switch access keep everything functional. That means less hassle at the dock and more time doing what you came for—running smooth and enjoying the day.

Why Buy OEM

Covers are all about fit and fabric quality. A genuine Mercury Marine part is designed around the real engine shape, not a rough guess. That OEM design helps it sit correctly, wear evenly, and last longer without stretching or developing weak spots.

Aftermarket covers can work, but they’re inconsistent. Some don’t breathe well. Some don’t line up with access points. Some just don’t stay put at speed. With OEM, you’re paying for the right cut, the right materials, and the confidence that it’s built to perform the way Mercury intended—right from the first install.
