Yanmar re-enters 50hp Diesel outboard market with Neander!!!!

The force of a Neander diesel engine is shown in its excellent torque, which is available even at very low speeds. The power advantage in comparison with gasoline-driven outboard motors can be felt from the very first seconds of operation.Because of its high torque, the 55 hp Neander diesel can directly compete with a 70 hp petrol-driven outboard.

Have a look at the engineering: wtf!!!

Technology : Neander Shark

The key enabler for a dual crankshaft engine with a constrained piston movement by two con-rods with theoretically no piston side forces is provision for forgiveness towards tolerances, which can lead to off-design positions of the piston in its cylinder bore and unfavorable mechanical effects like scuffing, sticking or simply higher friction as the least bad of effethis

PS: I had to look at the photos to understand this....lol.
