Mercury launches 250hp, 270hp V6 diesel engines
Focus on cost of ownership, better performance and more brisk acceleration as Mercury switches V6 sourcingMercury has launched a range of new 3.0-litre V6 turbo-diesel marine engines that it claims will outgun others in its class – yet lower the cost of ownership.
Key to the change is a swap from the previous-generation 230hp/260hp Volkswagen-sourced V6 TDI powerplant to a Fiat Chrysler Automobiles-sourced 250hp/270hp VM Motori unit that includes variable vane turbocharger technology for improved performance.
The sterndrive, inboard and water-jet capable engine will initially be offered in Australia in 250hp (paired with a ZF45 transmission) and 270hp (paired with a more cost-effective ZF63 transmission) configurations. A 150hp version developed specifically for Venice’s water taxi fleet is potentially in line for future global applications.
Turbocharged technology
Mercury’s more advanced 60-degree engine (the Volkswagen-sourced TDI was built into a 90-degree vee) uses a water-cooled variable vane turbocharger to deliver what the company claims is more early boost, reducing low-rev lag. Mercury claims the acceleration of the FCA-sourced V6 is best-in-class.
The new V6 also meets much stricter emissions standards.
Mercury claims the new powerplant has more suppression of noise, vibration and harshness than the unit it replaces, and is compatible with its joystick piloting system for both sterndrive and inboard systems.
“There is certainly customer demand for diesel power in this key horsepower range,” Mercury global inboard and sterndrive categories senior director, Reinhard Burk, said at the engine’s release at last week’s Sydney International Boat Show.
“Mercury already has a class-leading diesel portfolio and these engines add to that with their impressive low-end torque and exceptional durability,” he said.
Smart connectivity
Mercury says the engines are fully compatible with its SmartCraft system that gives owners access to engine-related data, as well as maintenance alerts and troubleshooting help.
They are covered by a three-year limited warranty, with an extra two years of limited warranty on major components.
