Mercury today unveiled at the Sydney Boat Show a line of 3.0-liter diesels for sterndrive, traditional inboard and waterjet applications. The engine is available in 150-, 230- and 270-hp ratings. It was developed and tested over the past three years with a focus on acceleration, reliability, ease of installation and maintenance, and mitigation of noise and vibration.

“There is an active segment of the boating market that requires the impressive low-end torque and exceptional durability of our diesel engines, and these new engines enhance our already class-leading portfolio of diesel propulsion systems,” Kris Neff, Mercury Marine vice president of global category management and strategic planning, said in a statement.

The diesels comply with Tier 3 emissions standards and are compatible with Mercury’s SmartCraft technology, which provides engine information, maintenance alerts and troubleshooting guidance. The engines also integrate with Mercury’s Joystick Piloting.
