Mercury – Xtreme Grease, 8 oz. | Lubrication | 92-8M0071838

Overview

Every mechanic and boater eventually settles on a grease they trust, and this stuff is one of those “always keep a tube on hand” products. Mercury’s Xtreme Marine Grease is made for the ugly jobs—parts that get hammered by heat, load, water, and salt. It hangs on where cheaper grease washes out, and it keeps moving parts from chewing themselves up after a long season of hard use. If you’re the kind of person who does your own steering, linkage, or trailer maintenance, this is the tube you reach for without thinking twice.

Performance & Practical Benefits

This grease sticks where you put it. It doesn’t melt out when things get hot, and it doesn’t wash away after running through rain, spray, or a salty weekend offshore. Parts move smoother, stay quieter, and are far less likely to seize after sitting through winter. If you’ve ever torn apart a steering system full of dried-up, chalky grease, you’ll appreciate how well this stuff holds up.

Why Buy OEM

Grease may seem simple, but marine gear is rough on lubrication. OEM grease is blended for real-world boating—heat cycles, vibration, saltwater, long idle hours. Cheaper generic grease breaks down faster and leaves expensive parts unprotected. This stuff doesn’t. It’s what Mercury techs use in their own shops for a reason.

FAQ

Q1: Where do boaters usually use this grease?
A: Steering linkages, throttle/shift cables, gimbal bearings, and trailer hubs see the biggest benefit.

Q2: Can this replace regular wheel-bearing grease on a trailer?
A: Yes—it's strong enough for wheel bearings and holds up well to water.

Q3: How does it handle saltwater?
A: Very well. It’s designed to resist washout and corrosion even when gear runs wet.

Q4: Does it work in hot and cold weather?
A: Yep—this formula stays stable whether you're running in summer heat or early-season cold.

Q5: Why pick this over general automotive grease?
A: Marine parts see far more moisture and load. Automotive grease simply doesn’t last in those conditions.
