Do you anticipate any move towards offering more than one standard size for the engine? If so, why and for what new target market?
The CXO300 is the ? rst in a series of high-powered per- formance diesel outboards to be developed by Cox Pow- ertrain. We have plans to expand our product portfolio to offer more powerful outboards, primarily to accommodate the growing demand for higher hp and bigger vessels.
Crucially for commercial operators, the CXO300 of- fers at least a 25% better range compared to a gaso- line outboard and is designed to last up to three times longer. The fuel savings are of course attractive, but what aspect of the design allows the engine to last three times longer?
