Mercury Diesel
Diesel 6.7L
There are Mercury diesel engines available to power an array of boats and propulsion systems, including sterndrives, inboards and Zeus® pods. All backed by the Mercury global service network. You decide where to go and what adventure looks like, and Mercury gets you there.
Overview
Take your life on the water to new destinations with the Mercury Diesel 6.7L engine. This turbocharged workhouse redefines diesel performance for sport yachts and other large vessels, blending premium comforts and extended range with exceptional speed and acceleration.
Closed cooling system A thermostatically controlled closed-loop freshwater cooling system protects the engine in both fresh and saltwater.
Smooth & Quiet From vibration-dampening engine mounts to an air filter strategically positioned to also reduce turbo noise, the 6.7L engine is optimised for a smooth, quiet ride.
HPCR fuel injection The high-pressure common rail (HPCR) fuel injection system fine-tunes the air-to-fuel ratio to enhance acceleration, top speed and efficiency.

Key Features
Easy ownership Top-mounted fluid reservoirs, a self-draining oil filter and an easy-to-reach oil dipstick keep maintenance and service simple.
Reduced weight With exceptional power-to-weight ratios, Mercury diesel engines pack big-time propulsion in a lightweight package. The difference: quicker acceleration, faster planing and easier handling.
Durability Durability and reliability are in the details, like thermostatically controlled closed-cooling systems and advanced corrosion resistance. Our diesel engines are designed to go the distance.
Efficiency Mercury diesel engines run clean and run easy, without the harshness or fumes from traditional diesels. They can also deliver up to 50% better fuel efficiency compared to gas engines of the same horsepower.
