Diemmax D6LR
6 Cylinders in line. A powerful smooth running engine with focus on power and low weight.
Overview
After 5 years we have decided it was time to set a new standard to our 6 cylinder range. We have developed a twin turbo engine on a entirely new platform. With this engine we set a new standard to performance and weight in its class.


lightweight, powerful
& safe
Lightweight
The lightweight motor ensures that
the boat can be (easily) lifted.
Compact
Compactness provides considerably
more space in the cockpit or more space for other equipment.
Money saving
250-350 HP, but still the lower fuel consumption rate of a modern diesel engine.

Specifications
The Diemmax inline six cylinder is specially developed for installation in sport boats and sport cruisers. With the use of lightweight materials like aluminum, titanium and carbon fiber the engine fits in all kind of pleasure crafts. By using diesel, the engines are better suited for tenders or yachts and fast professional boats. The twin turbocharged inline six cylinder has a maximum speed of 4000 rpm making this engine really suitable for fast lightweight boats. The inline six cylinder is only 770 mm wide and 900 mm long.
