Mercury 40 HP Carb Fourstroke

Mercury 40 HP Carb Fourstroke – Mercury FourStrokes have long led the pack in clean, quiet, fuel-efficient outboard power – and now the gap grows even wider. We combined innovative engineering with advanced reliability and features to make our outboards run clean, stay quiet, and deliver smooth, responsive performance – all while cutting your fuel and maintenance costs.

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 0-50 kph 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 EFFECIENCY

Clean Power

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.
