2013 Mercury FourStroke 25 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

The 25 and 30 horsepower FourStrokes have an industry-first battery-less EFI system for easier starting, smooth running, and improved efficiency. That’s not a misprint – they feature electronic fuel injection with no battery.
