Your 250 hp inline‑six may be a powerhouse on the water, but its cowling still needs a little TLC between runs. This custom vented splash cover is cut to match the tall L6 profile, so it slips on fast and stays put—no saggy corners, no highway flapping. The outer shell is Polysoft II: 95 % waterproof to shrug off spray, 5 % breathable to vent trapped moisture, and fully UV‑stable to keep that black finish from chalking in the sun. Inside, a soft, non‑abrasive liner treats the paint gently, while a 660‑lb tear rating makes the cover tough enough to laugh off stray hooks or dock bumps.

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

At a glance:

• Daily defense from UV fade, salt corrosion, bird droppings, lure dings, tow‑rope scuffs, and parking‑lot knocks
• Precision fit with an elastic hem—no straps or buckles to wrangle
• Vented panels stop ballooning at highway speeds and keep airflow around the powerhead
• Official Mercury graphics maintain the factory look
• Easy care—rinse with fresh water and let it drip‑dry

Use it for every launch, haul‑out, and fuel stop; switch to a full storage cover for winter layups.
