FIVE MINUTES WITH CHARLES GOOD, CHAIRMAN, COX POWERTRAIN “Getting the weight out and the package size down meant looking at every single component from a blank sheet of paper and seeing how we could maintain its strength, but do it with a minimum weight.”

I know that we can easily explore the technical speci? ca- tions of the CXO 300 online, but can you take a moment and discuss what you see as the key technical attributes and parameters of the engine?

This is a big and powerful engine, and

I think the key number is 300 horsepow- er delivered at 4,000 RPM. It’s a con- servatively rated engine. And we offer 479 ft. pounds of torque, which is a lot of torque for an engine of this size and delivered over a very broad rev range.

So the engines give a lot of grunt at low revs. Obviously the 25 to 30% fuel sav- ings versus gasoline. We offer two gear ratios, which is useful for different use cases. We also offer a wide range of leg www.marinelink.com 47
