75 EFI

Advanced power, commendable performance.

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

Built-In Durability

Every 75-115 horsepower Mercury FourStroke is built to deliver long-term reliable performance. Our fully filtered air intake protects internal engine components from potentially damaging dust and sand, while our advanced antidrainback oil system assures instant lubrication on start-up. In addition, the use of shared Verado components ensures the ultimate in mechanical toughness and reliability.

Maintenance-Free Valve Train

The 75-115hp FourStroke models feature the same valve train architecture as Verado – a robust design that is incredibly durable and maintenance-free for life.

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 75-115hp 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.

Electronics Leadership

Every Mercury 75-115hp FourStroke outboard features a 50-amp, 630-watt alternator, the most powerful in its class. This impressive alternator can power all your accessories – electronics, lights, livewells and audio equipment – throughout your trip.

Slow but Steady

Every 75-115 horsepower SmartCraft-equipped FourStroke features Troll Control, which allows you to set your engine speed as low as 650 rpm for trolling or running through extended no-wake zones.

 

FUEL EFFECIENCY

More for the Money

Mercury FourStroke engines feature Electronic Fuel Injection for better fuel economy along with easier, turn-key starting.

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.

 

Low Maintenance

Spend more time on the water

Every 75-115hp Mercury FourStroke, features an easy access automotive spin-on-type oil filter, oil fill and side mounted oil drain which makes for easy service and maintenance. You should spend more time on the water than servicing your outboard.
