Mercury® Engine:

Smooth and Powerful

This Mercury Diesel engine sets a new benchmark for low noise and vibration.

Powering More Than the Boat

To make every moment on the water count you need more than an engine behind you. You need a company. One that makes owning an engine so rewarding and trouble-free there’s nothing to worry about. Except planning your next adventure.

Diesel Drives

For every high-performing Mercury® Diesel engine, there's an equally high-performing drive. Working together to give you better performance. Whatever your boating style. Each drive is designed, built, and tested to deliver best-in-class reliability. So you can enjoy easy maintenance, low cost of ownership, and true peace of mind.

Mercury® Diesel

Mercury® Diesel engines start clean and pack a real punch. You gain quick acceleration and impressive throttle responses for fast planing times. And lose the problems traditionally associated with diesel engines. Ours are lightweight and 80 percent quieter than traditional diesels, with no smoke or odors. Get up and get going. Faster. Smoother. Better.
