V8 hero Russell Ingall enjoying Mercury Diesel power and Joystick control.
With the motor racing season slowing down for the holiday period, Aussie racing legend Russell Ingall is looking forward to spending some quality time in his newly renovated Riviera M400.
Powered by a pair of Mercury Diesel TDI 370hp engines with Bravo 3 drives, and controlled via Mercury’s Joystick Piloting system, the boat has been a special project for Russell who’s particularly proud of the outcome.
Clean, Quiet, Efficient.
Direct Injection (DI) technology uses injectors to spray diesel fuel atomized at 26,000 psi directly into the main combustion chamber of each cylinder. This process optimises fuel efficiency and minimises 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.
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.

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 crowd-pleasing hole shot, great acceleration, low planing times and ultra-smooth performance.
Mercury® SmartCraft® compatibility is built into these engines, delivering key information about vital engine functions on an easy-to-read LED display. SmartCraft Digital Throttle & Shift (DTS) offers smooth shifting, immediate throttle response and high-tech digital controls.
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.
