Test Run #2.
I raised the plate to 7 dots and speed was 76.8 at 6550 RPMs, but was way easier to control this time. She only started walking when I over trimmed it at the end. All and all Im very happy with the flash and looks like the prop I have will be good enough for me. I am still gonna have it sent off to Mark for work and see if its any better. As for fuel burn, she will drink it if I run her hard. But at cruising speeds Im any where from 500-800 RPM less than normal so it should balance out. Again its amazing how quickly the boat will race to 70 mph now.
Sounds like you got it moving
