So I ran my boat for the first time last night with the props spinning inward. The boat felt lighter and ran very level as if the stern was being carried higher. I could actually feel the boat on the pad above 65 mph. There was also no mid speed porpoising...at 6000/6200 rpm turning DAH chopper 26's I GPS'd at 70.44 mph with 3/4 tank of gas @ sea level with 80+ degree weather in flat calm water...It was getting too dark to continue making high speed passes...the best I saw spinning outward was 71.11mph so I'm very close in speed either way..the big difference is in the handling..it feels more fun to drive the boat spinning in. You have to drive it like a small V-pad hull and fly it on the pad with nimble corrections..
