FourStroke 50 EFI: Engineered for Boating Excellence

Mercury Four-Strokes have long led the pack with clean, quiet, fuel-efficient outboard power, and now the gap has grown even wider.

Mercury engineers implemented a new shift design which provides easier shifting. We refined the throttle resolution setting for smoother low speed operation. Plus, all the 40-60hp Four-Strokes feature new styling, graphics, a cowl latching system and much more!

The 40-60hp are available in both Standard and BigFoot gearcase models.

The Mercury 40-60hp Four-Strokes models distinguish themselves with many features you just won’t find on other engines. Features that make your boating experience a pure pleasure.

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.

Take it slow
On 40-60 hp equipped with SmartCraft, the TROLL CONTROL feature allows you to set your rpm as low as 700 for trolling or running through extended no-wake zones.

Less fuel, means more fun
The 40-60hp models deliver up to 40% better fuel economy than carbureted 2- stroke models and up to 20% better than directed injected 2-strokes.

Peace of Mind
ENGINE GUARDIAN uses more than 40 sensors to monitor functions of your engine. If the proactive operator-warning system detects a potential problem - such as overreving, overheating or low oil pressure - Engine Guardian sends out an alert and automatically reduces engine power to prevent damage.

Easy Shifting
A New PRECISION ENGINEERED SHIFT system delivers smooth, positive shifting for an improved driving experience.
