Mercury – Vented Splash Cover for 150hp Pro XS Engines | Engine Protection Cover | Black Polysoft II Material | 8M0228531

Overview

When you run a Mercury 150hp Pro XS, you get used to trusting that engine with your day – the long runs, the choppy afternoons, the calm nights idling back to the ramp. That kind of trust comes from experience, and this vented splash cover fits right into that feeling. It gives you the quiet confidence that your engine’s finish will stay protected no matter what the wind throws at you or how wet the ride gets. It’s the sort of gear you appreciate without thinking about it, because it simply does its job trip after trip.

Performance & Practical Benefits

Slip this cover over your Pro XS and you’ll immediately notice how naturally it fits. The Polysoft II material has enough backbone to feel secure but enough flex to wrap smoothly around the cowling without a struggle. Once it’s seated, it sits tight and steady, even when you’re trimming up and running through waves. No flapping, no shifting — just a secure barrier between your engine and whatever the day brings.

The breathable design keeps air moving, which helps avoid heat buildup and the trapped moisture that leads to dulling or corrosion. Spray rolls right off, sun fade slows down, and those little knocks from a cooler, rod case, or dockside misstep won’t leave marks behind. Out on the water, the cover becomes part of your routine — simple, protective, and dependable. It’s the kind of quiet upgrade that keeps your engine looking sharp long after lesser covers would have given up.

Why Buy OEM

There’s a reason seasoned boaters stick with genuine Mercury Marine parts: they fit right the first time. This splash cover is shaped for the real dimensions of the Pro XS, not a “universal” outline. The material is tested in true marine conditions, not just in theory. Aftermarket covers may look similar online, but they rarely match the long-term reliability or precise fit of an OEM design. If you asked me at the dock which one to buy, I’d tell you to go with the Mercury part number every time — it saves headaches, protects your investment, and lasts longer than you expect.
