Tier 2 - Diesel Workhorses

Quiet Ride

The high-pressure common-rail fuel-injection system not only ensures fuel economy, it also minimizes Noise Vibration Harshness (NVH), along with smoke and odor – the undesirable factors many boaters associate with yesterday’s diesels.

Repower Reasons

The lightweight, compact design of these diesel engines makes them ideal drop-in replacement power packages for many older, fuel-guzzling petrol engines. Mercury’s full range of drives offers outstanding versatility to owners of sterndrive-powered boats.

Peak Performance

Impressive acceleration and quick throttle response are delivered by the proven common-rail fuel system, which incorporates a turbocharger and seawater after-cooler. These engines combine smooth performance with key diesel advantages, such as high torque and optimum fuel economy.

Intuitive Design

A sophisticated Control Module and Mercury SmartCraft compatibility provide complete control over key engine functions. SmartCraft Digital Throttle and Shift (DTS) offers smooth shifting, immediate throttle response and high-tech digital controls.


Tier 3 - Fuel Misers with Turbo Direct Injection (TDI)

Clean, Quiet, Efficient

TDI technology uses injectors to spray diesel fuel atomized at 26,000 psi directly into the main combustion chamber of each cylinder. This process optimizes fuel efficiency and minimizes emissions, along with engine Noise, Vibration and Harshness (NVH) for an enjoyable boating experience.


The TDI engine block is fabricated from Vermicular Graphite Casting (VGC), which has twice the strength of grey iron and most of its attributes, but is 5% to 10% lighter. The end result is low weight, high strength and maximum heat transfer for optimum cooling.

Power & Performance

The low weight of these diesels results in best-in-class power-to-weight ratio. Combined with great low-end torque, the end result is crow-pleasing hole shot, great acceleration, low planning times and ultra-smooth performance.

Intuitive Design

Mercury SmartCraft compatibility is built into these engines, delivering key information about vital engine functions on an easy-to-read LED display. SmartCraft Throttle & Shift (DTS) offers smooth shifting, immediate throttle response and high-tech digital controls.
