When you're running a 350 hp inline‑six, the powerhead turns heads-this cover keeps it looking mint between runs. It's tailor‑cut for the tall L6 cowling, so it slides on quickly, cinches tight with an elastic hem, and never flaps on the highway. The shell is Polysoft II marine fabric: 95 % waterproof to shrug off spray, yet 5 % breathable so any trapped moisture can vent out. UV‑stable dyes and bold Mercury logos match your engine's factory look, while a soft, non‑abrasive backing protects that glossy black paint. With a 660‑lb tear rating, the material shrugs off rogue hooks and dock bumps without splitting.. The Mercury Vented Splash Cover is made to use while running your outboard. Why you'll reach for it every outing:. Daily defense from UV fade, salt corrosion, bird droppings, stray lures, tow‑rope scuffs, and parking‑lot knocks. Vented design keeps airflow moving and stops ballooning at speed. Precision fit: no straps, snaps, or guessing-just stretch it on and go. Easy care: rin
