Diemmax V12-Series

520-600 HP

DIEMMAX V12

This top-class engine is purpose-built for marine applications. This very powerful light weight engine is an extreme advantage in this class.

Due to its unique performance/weight and performance/space ratios (powerful in combination with low weight/compact shape), the motor is suitable for almost any application.

Thanks to the double turbo, the Diemmax V12 already delivers its maximum torque at low revs, so that the boat immediately gets up to speed. There is no turbo gap.

Overview

After 10 years of converting V12 engines for marine use we in 2015 decided to develop an entirely new engine. A compact and aluminium V12 diesel 100% developed for the maritime sector.

After more than 4 years of building and development, a prototype has now been run on the test bench for hundreds of hours. We will soon start with testruns in our ribs.

POWER

The Diemmax engines has, thanks to the twin turbo, an amazing low-end torque and no noticeable turbolag. This means that the peak torque is available almost immediately after accelerating.
