Twin 200's. 200 gallons on a heavy 27'. Total expected trip 150 miles. Use the 1/3 rule. 1/3 out, 1/3 back, 1/3 reserve for safety. Assume you get 1.0 mpg (overly cautious estimate - I assume you are going to be running + 4000RPMS for the 120 miles there and ******. Total range is 200 miles on a full tank. I wouldn't do it. Then again I don't like to take any chances that far out. If I had the DFI's or Four Strokes - yes. Almost double your range. Good luck. |
