Saltwater can take its toll on marine propulsion systems. This is why the SeaCore™ 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.

In developing the revolutionary SeaCore system, we’ve moved the entire industry forward in a way that makes other saltwater engines and drives seem instantly inferior. Rather than just enclosing the drive components in a plastic shell, we protect them all the way to the core with industrial hardcoat anodizing, a closed-cooling system and widespread use of stainless steel components. All of which makes for the ultimate in corrosion protection.

Unique six-step coating and painting process and the hardcoat anodizing of Mercury's exclusive XK 360 low-copper aluminum parts changes the molecular structure of the surface, making it extremely durable and corrosion resistant. If scratched, the surface inhibits continued corrosion. It's particularly useful for large runabouts, cruisers and performance boats that stay in harsh saltwater environments. The freshwater flush system is engine-mounted.

Corrosion Protection

• Industrial hardcoat anodized XK 360 aluminum alloy for Bravo® running gear
• MerCathode® active corrosion protection
• Closed-cooling system with five-year long-life coolant seals engine from saltwater
• SeaCore stainless steel package

Better Warranty

• Four-year factory limited warranty (three-year limited warranty for noncertified installations)
• Four-year limited warranty against corrosion failure*

Lower Maintenance

• 100/300-hour maintenance intervals
• Air-actuated raw-water drain
• Easy oil drain system
• Engine-mounted freshwater flush system – fish-friendly because no harmful chemicals used
• *U.S. and Canada warranty only.
