FEATURES:
- Power & Torque - The high-displacement turbocharged engine spools up massive torque, generating instantly responsive power to get big boats out of the hole and deliver a midrange punch when you need it.
- 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 optimized 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.
- Grid Heater - The 6.7L engine is ready for all-season adventure, with a grid heater that makes cold weather starts easy.
ADVANTAGE:
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.
