SeaCore Protection System

Mercruiser Seacore Protection System

The SeaCore™ Protection System from MerCruiser offers more than just improved corrosion resistance. It’s as close as a marine propulsion system can come to being corrosion-proof. Mercury Marine so strongly believes its corrosion protection is the best on the water that MerCruiser provides a standard four-year limited corrosion failure warranty.

The heart of the corrosion-resistant strength of the SeaCore System is the hardcoat anodizing of the drive alloy. This process actually changes the molecular structure of the XK-360 aluminium alloy, creating a shield against the ravages of galvanic corrosion. Hardcoat anodizing is also more abrasion resistant than case-hardened steel, but if the drive is scratched, the anodizing slows the destructive growth of corrosion through the drive surface.

The SeaCore System also provides corrosion protection for the engine with features like closed-cooling and a stainless steel package.
