Low RPM = More Fuel?

[bcurling]

I agree with you on propping correctly. I was not so much concerned about the cost of the fuel consumption as I was about the comment the fellow made to me regarding the two different sized motors on the same boat targeting the same speed. It just simply did not seem correct to my thinking. Just because one would be using a little larger motor and lugging it (according to him), about half throttle to achieve the same speed as the smaller motor means you would burn more fuel. That is the reason I reached out the forum in order to get some solid impute and confirm I have not been asleep for the past 68 years.
Still looking for my V20!
Thanks guys.
