Does anyone know if there are any technical websites out there that show boat and motor performance in reference to gas mileage? I contacted Yamaha and he quoted the specs to me over the phone but I'd like to look at it and compare them a little closer on my computer. I know the tests exist because he quoted me RPM's, gallons per hour, miles per hour, type of boat tested on and miles per gallon on a 90, 115, and 150 horse engine. The result was that a bigger engine is better as long as you back it off to around 2500 to 3500 rpm's. Run it wide open and it cuts your gas mileage in half!
