This engine was running on used engine oil, and used a large filter (near the tank on the back wall), a heating jacket (on the fuel filter), and a high presure pump on the end of the engine.
Apperently it runs fine, so far no problems. They have noticed that the exhuast smell is slightly different, and the sound is a little softer.
this is a classic piece of british engineering and for how long they ran cheap at half the price.

We live near the works and have a DM2, a new one is about £20,000 and a DM3 £27000. People do exagerate!

These could possibly be the single most expensive production twin-cylinder engines in the world.

I think it's more like £30,000-40,000- the equivalent of US$50-60,000. They have to be commissioned and each one is built by hand, with every single part (including the injection pump) made in house by RN.

@andywatson39 I think they are dearer than that now.

If you ran this engine this way in a boat and entered US waters you would be fined so heavily that your head would explode.

I would be very careful using ULO as fuel.

re buying
If you are buying consider a DM3 the price is a bit more but the peace this lovely engine gives you is well worth the extra, but have a direct drive off the engine to vehicle ( Lorry ) typeshaft direct to your prop.
