weekend fuel bill

[phatdaddy]

if your 200 is getting 5gph and you average 30 mph, you getting 6mpg. i believe the 10% rule is WOT. if you troll for 5 hours, you will get better gas mileage that if you cruise. thats why i use mpg, more usuful to my needs than gph. i don't have a fuel guage and don't really think they are very accurate on a boat. i set my gps when i fill up and figure 2mpg useage, that gives me a range of 120 miles with 20% reserve( actual mileage is 2.4) not saying this is the best method, but its the way my math challenged mind can handle it.
