Makers of the world famous Atomic-4 and pioneers in premium marine diesel propulsion, Universal has struck again with its latest release, the Universal B-Series. The B-Series is powered by the latest advancements in diesel engine design. Some of the benefits from these advancements include cleaner emissions, reduced noise levels, and increased horsepower at lower RPMs. All B-Series engines are naturally aspirated and deliver high low-end torque. This produces some of the most quiet and durable marine engines currently available.
If you’re looking to replace that aging Atomic-4, the Universal B-Series is still the boaters choice for Atomic-4 replacements**. The M3-20B offers many similar dimensional characteristics to the Atomic-4, making for a much easier installation.
**Universal Atomic-4 replacements are not direct drop-ins in all cases. Some engine compartment reconfiguration may be required.
