The 40, 50 and 60hp Mariner/Mercury models are available with either Standard or BigFoot gearcases. BigFoot models are perfect for pontoons and large boats, while the standard gearcases are ideal for aluminum fishing boats, bay boats, and inflatable boats.
Plus, every 40-60hp FourStroke features a single-latch cowl system for easy, quick release.
The 40-60hp Mercury engines are Electronically Fuel-Injected, which provides turn-key starting, increased power, improved fuel economy, and spectacular reliability.
Engine Guardian uses key external sensors to monitor all the major functions of your engine. If the proactive operator-warning system detects a potential problem – such as over-revving, overheating, or low oil pressure – Engine Guardian sends out an alert and automatically reduces engine power enough to prevent damage, but still allows you to get to shore.
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 40-60hp models with the innovative freshwater flush.
Only Mariner/ Mercury offers a three-year limited corrosion failure warranty.
Large-displacement dual overhead cam increases low-end power. Mercury FourStrokes consistently outperform the competition in 0-30 mph acceleration.
The precision engineered shift system in every 40-60hp FourStroke delivers smooth, positive shifting for an improved driving experience.
Every 40-60hp SmartCraft-equipped FourStroke features Troll Control, which allows you to set your engine speed as low as 700 rpm for trolling or running through extended no-wake zones.
All Mercury FourStroke engines are designed to run clean, helping to protect the environment for generations to come. Every Mercury mid-range FourStroke engine carries a CARB Three-star Ultra-low Emissions rating.
Gauge Your Fuel Economy- The new Smartcraft Mercury monitor constantly monitors engine RPM, speed, fuel consumption and trim to automatically calculate and guide you to maximize fuel efficiency, using yellow and green display colours to signify when engines are operating at optimal efficiency. This can result in a 10-20% increase in fuel economy.
Big-time power. With a longer design and bigger components, Mercury BigFoot was made specifically to deliver the type of power, thrust and control that wider, heavier boats demand. The BigFoot Difference (Blue shaded areas represent prop and gearcase advantages)
A low 2.42:1 gear ratio delivers thrust and maneuverability that big loads demand. Oversized Anti-ventilation Plate. Oversized design prevents air from being drawn into the prop, which increases efficiency.
