Easy-to-Maintain.

Easy-to-Maintain.

Mercury Diesel’s 3.0L engine simplifies maintenance by locating service points at the front of the engine. The oil, coolant, fuse box, seawater strainer, drive lube (sterndrive only) and power steering fluid (sterndrive only) service points are located at the front of the engine next to Mercury’s color-coded maintenance schedule to provide easy-to-understand service guidelines and easy-to-reach access.

Redefining the Standard.

Redefining the Standard.

The new Mercury Diesel 3.0L common-rail high-speed engine delivers exceptional performance and offers substantial improvements in acceleration and top speed – all made possible by a new water-cooled variable geometry turbocharger design (VGT). This matched system, plus a state-of-the-art engine control system, provides reduced time to plane and outstanding overall performance.

Reliability + Performance.

Reliability + Performance.

Enjoying your time on the water is more easily achieved with an engine that performs day in and day out. Mercury Diesel’s 3.0L engine is assembled in a state-of-the-art manufacturing facility that employs the latest in quality practices and control, ensuring ultimate confidence in reliability.

Quiet Performer.

Quiet Performer.

The Mercury Diesel 3.0L delivers exhilarating performance while minimizing noise and vibration, while the air filter doubles as a silencer that removes the turbo whine historically associated with diesel engines. The motor mounts are designed to minimize vibration. Having a conversation while cruising has never been easier.

Joystick Piloting for Inboards.

Joystick Piloting for Inboards.

The only joystick piloting system that’s compatible with gasoline or diesel inboard and tow sport engines.

The only joystick piloting system for single-inboard boats.

Many features available to make your tow sport adventures even more amazing - click here to find out more!

Corrosion-Resistance.

Corrosion-Resistance.

Mercury diesels feature state-of-the-art anti-corrosion, including a thermostatically controlled closed water-cooled system. Water-cooled engine oil, gear oil and steering fluid decrease engine-room temperatures, extending engine life. The SeaCore® system is available for the ultimate in saltwater protection.
