Yanmar 1GM Diesel Fuel Consumption
In response to your questions, I'm not moving the boat in the sense of from one harbor to another and, while I'm always interested in saving fuel, the question is not related to fuel inventory on a trip.
Being new to diesel engines, I'm just trying to get some idea how much fuel I will burn during this season of boating while motoring out to sail and return, maybe motoring 3 to 4 hours each time. While I know the tank is full, I'm not sure the fuel gauge is accurate. And, depending on how fuel is burned, It may be necessary to pump fuel out the tank at the end of the season to avoid fuel problems.
Thanks for your interest.
