Mercury – Grease, 16 oz. Tub | Assembly Lubrication | 92-8M0071836

Overview

When you’re putting an engine back together—whether it’s a small two-stroke or a big four-stroke—you want something on those fresh parts before they ever turn over. This assembly grease is the kind of stuff most mechanics keep nearby because it hangs on metal, doesn’t run, and gives the engine a fighting chance on that first startup. It’s meant for those moments when everything is clean and dry, and you need a layer of protection before the oil pump wakes up. If you’ve ever heard a dry startup and winced, you know why this grease matters.

Performance & Practical Benefits

Assembly grease makes the whole rebuild process feel smoother and safer. It stays where you put it—on journals, lobes, pins, or bearings—so you’re not worried about dry spots while you’re lining things up. When that engine fires for the first time, the moving parts already have a cushion, not bare metal scraping until oil pressure builds. It’s one of those small steps that gives you peace of mind through the whole job.

Why Buy OEM

Mercury builds this grease around the metals, clearances, and oil formulas their engines use every day. It won’t cause odd reactions, foaming, or thinning once the oil starts circulating. With OEM, you know the grease will behave the same way in the shop as it will on the water.
