Performance & Practical Benefits

The Quicksilver 853762T01 Aluminum Trim Tab Anode is more than just a replacement part — it’s a crucial piece of your boat’s protection system. By countering propeller torque, it keeps your steering smooth and responsive, especially at higher speeds or under varying load conditions. You’ll notice tighter tracking and less fatigue at the helm after installation.

But that’s only half of its job. This trim tab also acts as a sacrificial anode, absorbing electrochemical reactions that would otherwise corrode vital aluminum or Stainless Steel components on your outboard. Over time, that protection adds up — fewer costly repairs, longer engine life, and peace of mind every time you hit the water.

Built from high-quality marine aluminum, it’s tough, lightweight, and designed to resist wear in both saltwater and freshwater environments. The fit is precise, the install is simple, and once it’s in place, it works quietly and continuously to protect your motor and balance your ride. Inspect it seasonally, and replace it when you see pitting — that’s proof it’s doing its job right.

Why Buy OEM

Choosing a genuine Mercury Marine part like the 853762T01 Trim Tab Anode is about more than just compatibility — it’s about trust and protection. Mercury’s engineering ensures every piece is balanced, tested, and shaped to complement your outboard’s hydrodynamics. Aftermarket parts might look similar, but subtle differences in material composition or shape can affect steering or fail to prevent corrosion effectively.

This OEM anode is built from marine-grade aluminum that’s specifically formulated for Mercury’s alloys. It fits perfectly, performs consistently, and is proven to protect in all types of water. When you’re out there every weekend, reliability isn’t optional — it’s essential. With OEM, you know your engine’s protection is as dependable as your next start.
