BMW’s twin-turbocharged three-liter diesel engine is being used as part of a test program to convert the motor for marine use. Semcon, a Swedish product development company, and Cimco Marine, also from Sweden, are working together to develop a diesel outboard engine that produces more than 200 hp. The partners say the prototype will be produced after summer and plans are in place for the engine to go into production in 2020.

“This engine offers major potential for the marine environment,” said Henrik Einarsson, technical project manager at Semcon, in a statement. “High output and outstanding quality are important features for many people operating professionally, such as people running working boats and fast recreational boats. The enormous forces involved advance engineering — and are really good fun.”

The BMW engine is being modified and adapted for professional marine us. Semcon is handling the design work, calculation and simulation as part of the project. The next phase will involve devising a prototype that will be water-tested.

“The outcome of the pilot study is extremely positive,” said Cecilia Anderberg, CEO of Cimco Marine. “We have worked together with Semcon to identify what measures are needed for us to embark upon the next phase. This gives us every chance of taking the project to the next level.”

Cimco Marine developed the world’s first diesel outboard and has many patents on its initial model.
