MERCURY 150hp FourStroke Vented Splash Cover — Black Polysoft II, Running-Capable Protection

MERCURY's vented splash cover for 150hp FourStroke outboards is a custom-fit, running-capable shield that protects your engine from spray, UV, salt, and debris.

When you spend time on the water you want an outboard that looks and runs like new for seasons to come. This black splash cover is engineered specifically for Mercury 150hp FourStroke engines and made from marine-grade Polysoft II fabric, giving you on-water protection without removing the cover when the motor is operating. Its vented construction balances airflow and protection so you can fish, cruise, or transit without exposing the cowling to everyday wear.

How does this splash cover protect my engine while I’m underway?

The cover blocks direct spray, salt, and airborne debris that cause surface wear and staining during normal use. Because it slips over the cowling with a tailored fit, it limits abrasion and prevents water spots and UV bleaching that accumulate over time.

• Stops salt spray and road-topper spray from reaching painted surfaces.
• Reduces UV fading and oxidation on factory finishes.
• Shields against branches, hooks, and incidental dings while underway.

Can I run the engine with the cover installed?

Yes — the vented design allows the engine to operate with the cover in place, so you don’t need to remove it for short runs or while fishing. Vents let heat and exhaust disperse while still protecting the external surfaces from moisture and particles.

• Strategic vents prevent heat buildup during operation.
• Maintains airflow needed for normal engine function without exposing the cowling.
• Ideal for transit, trolling, and dockside use when brief running is expected.

What is the cover made of and how durable is it?

This cover uses Polysoft II marine-grade material, chosen for resistance to UV, salt, and everyday abrasions. The fabric is built to withstand recurring exposure to harsh marine conditions while remaining lightweight and flexible for a snug fit.

• Marine-grade Polysoft II resists fading and salt corrosion.
• Flexible tailoring provides a secure, low-profile fit.
• Constructed to limit water spotting and surface scratches.

Will this fit my outboard and how easy is it to use?

The cover is specifically tailored for Mercury 150hp FourStroke outboards, providing a close fit that stays secure during typical boating activities. It’s designed for straightforward installation and removal so you can cover the engine quickly at the dock or before a trip.

• Custom-cut for Mercury 150hp FourStroke cowling dimensions.
• Quick on/off for roadside storage or pre-launch protection.
• Low-profile design avoids interference with handles and fittings.

Who is this for? Boaters who own a Mercury 150hp FourStroke and want to extend the outboard’s appearance and resale value without disrupting normal use will appreciate this vented splash cover. It’s best for anglers, day-cruisers, and weekend explorers who need practical, running-capable protection against spray, sun, and everyday wear. If you regularly operate in salty or sunny environments and prefer a tailored, durable solution, this cover helps keep your outboard looking cared-for season after season.
