    Frankie – glade to hear of your project. What you are doing is quite commonly done to improve fuel economy and lower total fuel costs.

    I am repowering a 1990 35 foot main ship mediterrane convertible replacing 2 454 gas engines, with a pair of BEAST 400T PENINSULAR 270 HP MARINE TURBO DIESEL

    The engine is rated at 270 Horsepower. You may get a little more than that depending on how it’s tuned. Fuel burn depends on weight, speed, prop slip, and prop selection. Our guess would be in the neighborhood of 10 gallons per hour per engine.

    We think we know the boat you’re looking at. Please give us a call if you have any questions (616) 530-1298.

    Hi, I have not heard of Peninsular diesels befor today. I had a marina in St augustine i the 70s and worked on cats,jimmies, cummins,but never saw a Peninsular until today when I was looking at a 28 1987 Bertram and it has a par of 270’s in it. What kind of power can I get from them and fuel useage

    Thanks Peter Murray
