Mercury – Extreme Grease with PTFE | High-Performance Lubricant | Marine Formula | 8M0071837

Overview

If you’ve spent enough time around boats, you know the little things make all the difference especially when they move, pivot, or carry weight day after day. There’s a certain comfort in grabbing a grease gun filled with a lubricant you know will hold up in salt, heat, and heavy load without breaking down. That’s what this Mercury Marine part brings to the table: confidence. Whether you’re prepping for a long run offshore or just keeping your steering and throttle feeling smooth around the marina, this grease gives you that steady reassurance that everything will move the way it should. No surprises, no sticking cables—just clean, reliable motion.

Performance & Practical Benefits

Marine hardware takes a beating. Saltwater, vibration, and constant motion can dry out cheaper lubricants quickly, leaving critical components feeling stiff or worn. This Mercury Marine part delivers a tight, smooth layer of protection that stays put—even under load or in harsh coastal conditions. The PTFE additive helps create a slick, durable film that reduces friction and keeps parts moving freely.

When you apply this grease to steering cables or gimbal bearings, you’ll feel the difference almost immediately: smoother wheel turns, steadier trim movement, and quieter articulation. It resists washout and won’t thin out under heat, so your equipment stays protected longer. And because it’s designed for high-pressure contact points, everything from wheel bearings to U-joints can handle long seasons of use without feeling gritty or worn.

Why Buy OEM

OEM lubrication products aren’t just relabeled generic greases—they’re built around the real stresses Mercury engines and components face on the water. This formulation is engineered to withstand saltwater exposure, heat cycling, and heavy mechanical loads. An aftermarket substitute may look similar on the shelf, but it rarely holds up the same way once you’re underway.

Choosing the Mercury OEM grease means fewer failures, smoother operation, and longer service intervals. It’s a smart investment, especially if you rely on your boat for long weekends, towing kids on the lake, or punching through chop offshore. When a fellow boater asks what you use, you can honestly say you choose what works the first time, every time.
