Yes, the Deutz was an extremely powerful, fuel efficient engine. Best in the world. I have a customer who had a Deutz eng. in his R50 and when he bought a 62 w_cummins, he was not a happy camper with fuel consumption. 12 gallons an hour is what his burns now. We had to send his pump off after he first bought it to get it "set up" because govenors weren't working right and low power. It has plenty of power now, but it "drinks" the fuel. He made the comment that he had heard when he bought the first 50 that the engine parts were expensive, but he said the diff in cost of fuel would make up the diff if anything went wrong.
