If you think about it, boat engines can't shift, their performance depends on the efficiency of the prop, that prop, co trolls the angle of attack and amount of throttle required to make that engine work, both props were tested under different conditions on different days, but the feel of the boat and amount of used fuel tells me alot, I have the capability of running on a remote 6 gallon tank, which I often do between trips to the fuel dock that is closed more than its open, 6 gallons with 4 blade prop, takes me out to my lobster pots and back to the mouth of the river before I need to run on the main tank, the SWW 3 blade allows me to make it 3 more miles to the marina with fuel to spare in the 6...pretty overwhelming evidence in my book.
