. <<<He still would not be as efficient as a trawler atthese displacement speeds, but he will be much more efficient than he is at higher speeds. To put an actual number on it, however; he would have to go do some testing. If he did that, it would not surprise me at all to see him getting perhaps four to six mpg at six knots.>>> Paul, Good estimate, if he can go that slowly. Maybe he can on one engine. Some of these highly powered sport fishing boats can't even get down to no wake speed at dead slow idle, they must shift in and out of gear. If a range improvement is necessary to make the delivery, removing one prop will help substantially. Mark Richter _________________________________________________________ DO YOU YAHOO!?
