Mercury FourStrokes have long led the pack in clean, quiet, fuel-efficient outboard power – and now the gap grows even wider. We combined innovative engineering with advanced reliability and features to make our outboards run clean, stay quiet, and deliver smooth, responsive performance – all while cutting your fuel and maintenance costs.
Built-In Durability
Every 80-115 horsepower Mercury FourStroke is built to deliver long-term reliable performance. Our fully filtered air intake protects internal engine components from potentially damaging dust and sand, while our advanced antidrainback oil system assures instant lubrication on start-up. In addition, the use of shared Verado components ensures the ultimate in mechanical toughness and reliability.
Maintenance-Free Valve Train The same lifetime maintenance-free valvetrain design found in our 150 FourStroke engines makes the 75-115hp FourStroke outboards incredibly durable.
Mercury FourStrokes deliver powerful saltwater protection by using stainless steel components, hard anodizing, engineered polymers, and an exclusive multistep painting and coating process. Saltwater maintenance is made easy in the 80-115hp models with the innovative freshwater flush.
