Mercury 40 HP EFI Bigfoot Fourstroke – BigFoot engines are built with a taller, heavy-duty gear case, larger gears and shafts (up to 33% larger than standard outboards) and that places the propeller deeper in the water dramatically improved performance by been able to running a larger propeller.
Houseboats, Pontoons or heavy vessels are unique; they sit high above the water and are hydro-dynamically different from other boats. In response to those and other challenges, Mercury developed BigFoot, the industry's only outboard engine made specifically for Houseboats, Pontoons or heavy vessels.
BigFoot engines are built with a taller, heavy-duty gear case, larger gears and shafts (up to 33% larger than standard outboards) and that places the propeller deeper in the water dramatically improved performance by been able to running a larger propeller. The BigFoot's propeller has up to 20 percent more surface area than standard propeller, providing more working surface for greater overall thrust, acceleration and maneuverability.
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.
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.
Quicker is Better
Large-displacement dual overhead cam increases low-end power. Mercury FourStrokes consistently outperform the competition in 0-50 kph acceleration.
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.
All Mercury FourStroke engines are designed to run clean, helping to protect the environment for generations to come. Every Mercury FourStroke engine carries a Three-star OEDA 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 colours to signify when you're operating at your optimal efficiency. This can result in a 10-20% increase in fuel economy.
