Your 40 hp four‑cylinder outboard works hard—give the cowling an everyday shield that’s just as tough. This cover is sewn from Polysoft II, a soft‑lined, marine‑grade fabric that’s 95 % waterproof to shrug off spray yet 5 % breathable so trapped moisture can escape instead of turning to mildew. UV‑stable pigments and official Mercury graphics keep the look factory‑fresh, while a 660‑lb tear rating means it won’t rip if a hook or dock line snags it.

The Mercury Vented Splash Cover is made to use while running your outboard

Quick reasons you’ll want it on before trailering or docking:

• Blocks UV fade, bird droppings, salt corrosion, stray lures, tow‑rope rub, and parking‑lot bumps
• Elastic hem pulls tight for a no‑flap fit even at highway speeds
• Non‑abrasive polyester backing protects the paint—no scuffs or scratches
• Vented panels prevent ballooning while maintaining airflow around the powerhead
• Cleans up with a simple freshwater rinse—no soap needed

Cut specifically for Mercury 40 hp 4‑cyl. engines, this splash cover fits like a second skin. Slip it on for day‑to‑day protection, then switch to a full storage cover when you pack the boat away for the season.
