Re: Trying to Max. fuel mileage
There is a point where the engine sounds kinda gravelly, then as you advance the throttle, it suddenly sounds smooth. It is this point that you will realize the best economy. On my setup, this is achieved around 3800 rpms, depending on load. It is also true that minimum planing speed will give decent results, but you want the engine working within its powerband, and minimum planing speed may be too slow on your setup. I know on my setup minimum planing speed is too slow, and I have yeilded less than optimal economy at that speed. You could try some experimenting as well. It is hard to give a set number, because it can vary from trip to trip, even day to day. Good luck...
