Introducing the Universal B-Series - The Legend Continues
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 youíre looking to replace that aging Atomic-4, the Universal B-Seriesis still the boaters choice for Atomic-4 replacements**. The M-25XPB and M3-20B offer many similar dimensional characteristics to the Atomic-4, making for a much easier installation.
Universal holds a large inventory of spare parts for your engine including easy-to-buy spare parts kits and gasket sets tailored to your particular engine. Itís easy to see why Universal is as popular today as it was 100 years ago. Stop by your local Universal Distributor or Dealer today to learn more about the latest in Universal Marine Power.

**Universal Atomic-4 replacements are not direct drop-ins in all cases.
Some engine compartment reconfiguration may be required.
