Took the boat out today, left the ramp and couldn't make power to plane, couldn't get rpms over 3K at full throttle, I eased around and alternated between easing and trying to open her up and it did nothing but stall then all of a sudden after about 10 minutes of that it just took off, I ran it wide open at 4800 for a good 5 minutes then back to idle, when I tried to take off the second time it stalled again breifly then took off again running like a champ 4800 rpm 50mph, this happened several more times before I loaded her up, any suggestions?
