It's expressed in lbs. of fuel per HP per hour (I think). I had it once, but this darn computer has forgotten where I...er, "it" stored it. Thanks in advance. It is called "specific fuel consumption." Common units are grams of fuel per kW per hour, or pounds of fuel per hp per hour. I normally invert the number and convert it into hp per hour per gallon of fuel. In the trucking and industrial heavy equipment world, I'm used to using 20 hp per one gallon per hour as sort of a good rule of thumb, even though some of the new engines are boasting values as high as about 24. In the world of recreational boats, however; things are not nearly so efficient. Values of perhaps 15-17 are much more reasonable for the typical recreational trawler. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ :: Paul and Cindy Kruse :: KJV Joh 14:27 Peace I leave with you, 165 South Kenneth Court :: my peace I give unto you: Merritt Island, FL 32952 :: not as the world giveth, give I unto you.
