VGT design
Closed cooling system
A thermostatically controlled closed-loop freshwater cooling system protects the engine and turbocharger in both fresh and saltwater.
Advanced ECU
Our advanced engine control unit (ECU) intelligently manages engine systems to reduce emissions and optimise overall performance.
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.
Ample charging output
A powerful alternator delivers 110 amps of charging power at wide-open throttle – perfect for keeping onboard electronics running long into the fun.
SeaCore
Take on the toughest marine conditions with the available SeaCore® system. It is an entire package of durable, corrosion-fighting technology that offers an extraordinary level of protection.
Diesel diesel advantages
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.
