Diemmax V12
This top-class engine is purpose-built for marine applications. This very powerfull light weight engine is an extreme advantage in this class. Due to its low weight and compact shape, the motor is suitable for almost any application.
Overview
2005 Diemmax has started building 6 cilinder marine engines and converting V12 engines for marine use. Customers in the 520-600 HP segment were designated 2 maintenance-sensitive V8 petrol engines or heavy converted diesels. Diving into this niche turned out to be a hit. Demand for the V12 was enormous.
The interest in the segment was so great that we in 2015 decided to develop an entirely new engine. A compact and aluminum V12 diesel 100% developed for the maritime sector.
For example: Hundreds of tenders are built every year in the targeted class. For this segment the Diemmax V12 engine has significant customer benefits.
After more than 4 years of building and development, the first test runs will be made in December 2020 and a prototype has now been run on the test bench for hundreds of hours.
