    That’s what I thought too! Thanks for the input. I’m headed for some xd100 and give ole Johnny a good swig. Let’s see how he pushes the 14ft alumacraft now! I’d be satisfied with just a little better 1st start out of the dock and see how that goes. I’ll test a small amount about 40:1 and a 24:1 separate mix in my tank at home today with my test prop and see how it goes.
