Mercury – Vented Splash Cover | Verado Series | White Polysoft II Fabric | 8M0228521

Overview

If you’ve ever come back to the dock with the wind in your face and spray coming over the bow, you know how fast an engine cowling can go from clean to crusted. Most of us don’t mind a little mess, but we do care about keeping our gear in good shape—especially when it’s a Verado sitting back there. This vented splash cover is the kind of protection you don’t think about much once it’s on, and that’s exactly the point.

It lets you run the boat like you normally would while helping your engine stay looking sharp. The fit feels intentional, the material feels right, and you get that steady comfort of knowing the finish is guarded from the daily wear that adds up over a season.

Performance & Practical Benefits

On the water, the difference is simple: things stay cleaner, and the engine stays better protected from the stuff you can’t always prevent. This cover sits snug and secure, so it doesn’t feel like an add-on that’s going to shift around the moment you throttle up. It’s the kind of fit you want when you’re running through chop—tight, steady, and not flapping at the edges.

The Polysoft II fabric has a tough outer feel that shrugs off water and sun, but the inside is kinder to your cowling. That matters when you’re covering a premium finish. Over time, it helps cut down on water spotting, salt film, and the small scuffs that happen when you’re docking, loading, or just moving around the stern.

And the vents are there for a reason. You’re not forced to choose between protection and proper airflow. With side vents, exhaust ports, and switch access, you can keep your usual routine without fussing with the cover every time you need to run the engine.

Why Buy OEM

A cover like this only works if it fits right and holds up. That’s where a genuine Mercury Marine part earns its keep. It’s designed and tested around the real engine shape, so you get a cleaner install and more dependable performance than many “close enough” options. OEM also tends to mean better long-term wear—less stretching, fewer weak spots, and fewer replacements down the road.

If you’re already taking care of your engine with the right fuel, the right service, and the right habits, an OEM cover is just the practical next step. It’s a small decision that helps protect a big investment.
