Thanks a bunch for all of the help. First of all, running wide open I can spin any 3 of the props past 5500. The trophies are giving me the best of luck with the 24p spinning up to 5800 running WOT. When I gun it from a stand still the prop is not cavitating at all. If anything, I probably need to pull another plug. It just takes the motor a while to start pulling 3500 + rpms. It takes about 10 seconds to get spinning in the 4000 range. It almost feels like it is bogging down until it gets in the higher range of rpms. Again, this might be how this boat performs. Just trying to figure it out as it is my first boat. Also, should I be able to run over 64 mph. I know that the boat has the minimum HP on it. The guy that I bought it from said he was able to get 67 with him and his tackle and a quarter of a tank. I just think that might be stretched a little. Not to mention he did not have a GPS unit on the boat when he had it. I put a humminbird 997 on it!
