More Features, More Fun.

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 60hp 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 40-60hp FourStroke features a single-latch cowl system for easy, quick release.

RELIABILITY

Easy Starts. Smooth Running.

The 40-60hp 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 40-60hp models with the innovative freshwater flush. And only Mercury offers a three-year limited corrosion failure warranty.

PERFORMANCE

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 40-60hp FourStroke delivers smooth, positive shifting for an improved driving experience.

Slow but Steady

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.

FUEL EFFICIENCY

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.

Command Thrust

Need more muscle to move your boat? Mercury's mighty Command Thrust package provides greater acceleration, better handling, awesome maneuverability, and superior stopping power.

Bigger Footprint

The larger “CT” gearcase creates a bigger footprint in the water, which provides more leverage to control your boat. The larger torpedo, combined with a bigger-diameter prop, can lift a heavy boat onto plane more easily and hold it there at lower speeds without impacting top speed.

Gearcase Selector

Note: The above recommendations should be considered guidelines, not absolutes. Proper boat setup is always dependent on the individual boat model, engine height, propping, and normal running loads. In general, a Command Thrust model provides more lift than a standard model, and will perform best on boats that typically run “wet” (boats that typically operate with more running surface in contact with the water while on plane). As such, there will be exceptions to the above recommendations. Your local Mercury dealer can help you select the best model to maximize your boat’s performance.
