Mercury 2013 FourStroke 50 EFI Bigfoot Outboard Motors
Standard Features


Mercury FourStrokes have long led the pack with clean, quiet, fuel-efficient outboard power, and now the gap grows even wider. Whether you pilot a small fishing boat or a party on a big pontoon, there’s a Mercury FourStroke that fits the bill.

The 40, 50, and 60 horsepower 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.

No matter the size, these FourStroke outboards are a pleasure to drive. Mercury engineers have created a unique design for easier shifting and refined the throttle resolution setting for smoother low-speed operation. Plus, every 40 - 60 horsepower FourStroke features a single-latch cowl system for easy, quick release.

SmartCraft Engine Guardian

Standard Features

Easy Starts. Smooth Running
 The 40 - 60 hp Mercury engines are Electronically Fuel-Injected, which provides turn-key starting, increased power, improved fuel economy, and spectacular reliability.  
Peace of Mind
 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.  
Superior Corrosion Protection
 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 - 60 hp models with the innovative freshwater flush.  
Quicker is Better
 Large-displacement dual overhead cam increases low-end power. Mercury FourStrokes consistently outperform the competition in 0 - 30 mph acceleration.  
Easy Shifting
 The precision engineered shift system in every 40 - 60 hp FourStroke delivers smooth, positive shifting for an improved driving experience.  
Slow But Steady
 Every 40-60 hp 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.  
Clean Power
 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
 Introducing the new ECO-Screen feature of the SmartCraft MercMonitor. The ECO-Screen constantly monitors engine RPM, speed, fuel consumption and engine trim to automatically calculate and guide you to your maximize fuel efficiency. This user-friendly feature utilizes yellow and green display colors to signify when you’re operating at your optimal efficiency. This can result in a 10 - 20% increase in fuel economy.
