Saving boat gas.

With due respect to NoBozo, I don't find GPH useful for determining the efficiency of my boating. It's way too dependent on speed. If I take an extra pass through the Weirs channel or Sally's gut my GPH will improve but I really havn't done anything to improve my boat operation.

You really need an fuel flow meter to monitor in real time. Say I want to boat over to Wolfeboro, what is best speed to go there. The very best speed will be around 5 MPH but that's four hours round trip. What's the best on-plane speed? I don't have the equipment, but I can guess it's better at 25 MPH than at 12 MPH. But my GPH will be better at 12 MPH.
