Time-tested and straight-out reliable, the Alpha One is the most popular sterndrive in the world.
When it comes to high-performance sterndrives, Bravo One stands out.
Big cruisers and houseboats with high-torque engines need big lift and thrust.
Experience the power of three.
Want Nothing But the Best?
Start at the Core.
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.
