Mercury – Square Aluminum Anode | Corrosion Protection | Aluminum Alloy | 875208

Overview

If you spend enough time around outboards, you learn which parts quietly save you money — and anodes are high on that list. The Quicksilver 875208 Aluminum Anode is one of those small but essential guardians that protect your engine from the steady, invisible wear of galvanic corrosion. It’s a simple piece of metal, but the reassurance it gives you out on the water is real. Knowing your outboard’s housing and key components are shielded lets you relax and enjoy the day instead of worrying about long-term damage sneaking up on you.

Key Features

• Square aluminum anode designed for Mercury and Mariner four to 9.9 horsepower outboards.
• Also fits many 10–30 horsepower four-stroke engines.
• Aluminum alloy meets marine protection standards for freshwater and saltwater.
• Quick replacement using existing hardware.
• Built to OEM specifications for consistent corrosion defense.

Engine & Boat Compatibility

• Fits Mercury and Mariner 4–9.9 horsepower outboards.
• Works with many 10–30 horsepower four-stroke models.
• Ideal for jon boats, small fishing skiffs, inflatable tenders, dinghies, and utility boats.
• Compatible with both freshwater and coastal boats.

Performance & Practical Benefits

This little square anode absorbs corrosive energy before it ever has a chance to attack your outboard’s aluminum components. Over time, that protection translates to smoother operation, fewer repairs, and a longer-lasting engine. You’ll notice the difference during seasonal inspections — instead of finding pitting on your gearcase, the anode carries the wear, just as it should.

Aluminum anodes are especially effective for mixed-water boating. Whether you launch in freshwater one week and brackish water the next, this alloy adapts well and offers consistent protection. Replacement is simple: remove the worn anode, bolt on the new one, and you’re ready to get back on the water.

It’s an easy job, but one that makes a noticeable difference in how well your engine holds up year after year.

Why Buy OEM

Anodes function properly only when they are made from the appropriate alloy and sized precisely for the engine they are meant to protect. Generic anodes often contain inconsistent metal blends or have imprecise dimensions, which can diminish their effectiveness. With Quicksilver OEM anodes, you can be assured that the alloy meets Mercury Marine’s standards for corrosion protection.

You’re not just putting on a piece of metal — you’re installing a part that was engineered to be the sacrificial shield your outboard depends on.
