We have recently purchased a 35' CT Sundeck Trawler with twin 85 hp (not turbocharged) diesel Perkins (Detroit Diesel) engines. Does anyone have an idea regarding how much fuel consumption I should expect. We haven't really used to boat enough to determine how much fuel we are using, but we are conservative and don't push the engines, probably cruising around 7-8 knots. Any communications are welcomed...Thanks..
