    I don't know what model you are asking about, but my 53EDMY (58000lbs), gets about 1nm/gal at 10knots and .5nm/gal at 15knots. My 6v92s are 465hp. Hope that helps.

    Jim, I thought the same thing then wondered why someone looking for a 90' boat would be worried about fuel burn.

    36-40gph at 1900-1950 rpm for 500HP TAC2 (twin dry turbo) 6V92s is about right. Thats what my floscans said I was burning, and they were nuts on.

    What speed that produces is up to the boat, of course...... and this assumes you're propped correctly and not overloaded.
