Problem finally solved , the mechanic that serviced the engines prior to my last trip, turned off the starboard fuel return valve on top of the tank for some unknown reason. It was discovered after the fuel flow magically returned to normal for the last 10 minutes of a trip to Point Judith, making me temporarily happy until after topping off the fuel only to find 10 gallons (at least) under my engine from the ruptured fuel return line. Replaced line, opened valve, fired mechanic ,fuel flows normalI have a 2006 44, on the last trip of the season , and continuing this season, I've noticed a fuel flow split starting at 2150 rpm. Port engine 14.8, Stb 12.1. No smoke from the port engine. The load was also split , at 79%, Port 62%, Stb 47%. the boat tracks straight, and after a 4 hour run and topping the tanks, both were within 2 gallons of each other. I believe I have an indication problem( I hope) and was told that the engine load uses a calculation of fuel flow. Does anyone know where the fuel flow transducers are and if they can be swapped?
