This is just a question -- if you don't (didn't) know what the WOT rpm is, how do you know you need to change prop pitch?

some people told me I should change as I'm useing so much fuel, I went from Hamilton to port delhousie and back and used about $180.00 in gas
I was useing a 15 x 151/2 prop.

Re: recomended WOT RPM for OMC

About how many miles is it?What rpm and speed did you run?What is the present max rpm and speed.$180 doesn't tell us much. How about gallons or at least price per gallon?What size boat?MY educated guess that motor would use about 25 to 30 GPH(gallons per hour)at wide open throttle.Get us the details and we can figure where you are at.
