It will flip over by 45mph with this engine. I'd need to go back to a 2-stroke on a smaller prop to lower the CG and get more rpm. But really - this is not a speed machine. It's fun the way it is. I wanted to tune up the 4-stroke so I can clean it up and oil it. I have some other engines I want to try on it. I might even go crazy and stick my Jett .56LX on it for an experiment. We've already swapped the Jett onto another boat previously... May as well keep moving the $495 slug around.
