2026 Mercury Marine® Mercury Diesel 270hp Sterndrive

Built to explore with comfort, the smooth and quiet Mercury Diesel 3.0L engine will shift your expectation of what diesel performance feels like

Features may include:

• Whether it’s getting out of the hole, cruising on plane or running wide open, the variable geometry turbocharger (VGT) design automatically optimizes power and torque to meet demand.

• A thermostatically controlled closed-loop freshwater cooling system protects the engine and turbocharger in both fresh and saltwater.

• Our advanced engine control unit (ECU) intelligently manages engine systems to reduce emissions and optimize overall performance.

• The high-pressure common rail (HPCR) fuel injection system fine-tunes the air-to-fuel ratio to enhance acceleration, top speed and efficiency.

• A powerful alternator delivers 110 amps of charging power at wide-open throttle – perfect for keeping onboard electronics running long into the fun.

• Take on the toughest marine conditions with the available SeaCore® system. It’s an entire package of durable, corrosion-fighting technology that offers an extraordinary level of protection

• Top-mounted fluid reservoirs, a self-draining oil filter and an easy-to-reach oil dipstick keep maintenance and service simple.

• 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 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.

• 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
