Performance & Real-World Benefits

The 802859A1 2-4-C grease protects everything that moves — from your boat’s steering system to your trailer wheels. Its advanced PTFE formula forms a slick, water-resistant barrier that prevents corrosion and reduces friction, even under heavy loads.

It stays in place, won’t melt, and won’t wash away after hours on the water. A thin coat during regular maintenance helps extend the life of your equipment, reduce squeaks, and keep everything working smoothly trip after trip.

When you use genuine Mercury grease, you’re using the same product trusted by technicians who maintain Mercury engines around the world. It’s tough, versatile, and proven to protect where it matters most.
