Cimco Marine AB is working on a new-generation 3.0-liter diesel outboard with six cylinders, and two turbochargers. The foundation for the motor is being supplied by BMW. Internally, Cimco is calling it the Bison project. Production is scheduled to begin in Spring 2020.
“The Bison project is proceeding with unchanged intensity,” Per Wigren, project manager at Cimco Marine AB, said in a statement. “Identified improvement potential from the first sea-going concept prototype is now being fully implemented in the next generation prototype. The Bison P1A will be delivering 300 hp on the propeller shaft.”
Development of the OXE Diesel 300 has reached the second prototype phase. In the first set of prototypes, the motor was tested in cells and on the water. The next generation is expected to go through ocean testing in July.
Cimco Marine says the OXE Diesel 300 should consume about 40 percent less than a comparable 300-hp gas outboard. The company also claims that carbon dioxide will be reduced by more than 35 percent and carbon monoxide will be cut by 99 percent while nitrous oxide will be decreased by 70 percent.
Two of the factors for the reduced emissions are that the powerhead for the new motor is derived from a BMW automotive engine and that the motor runs on diesel fuel.
The engines are already designed to comply with Euro 6 emissions regulations in cars.
