Mercury 80 HP EFI - 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.
Every 75-115 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.
