First test run of my 1963 AeroCraft with a 1963 Johnson 40 HP. Plus a shot of my 1956 Gator tilt trailer.
My wife and I did get 30.9 mph per hand held gps with a 12 pitch prop. I have three props two 12 and one 10 pitch. Hope to get a hold of a 14 pitch to see what that will do. Seems to be about 3.5 mph difference between the 10 and the 12. I did try a run by myself but spun the hub at 30.5 mph.
